Intake variable valve timing solenoid replacement is one possible repair for a 2007–2010 Hyundai Elantra with the 2.0L four-cylinder engine that has rough idle, poor acceleration or cam-timing faults such as P0011 (intake cam timing over-advanced/system performance) and P0016 (crankshaft-to-camshaft correlation, Bank 1 Sensor A). These symptoms and codes do not prove the oil-control valve has failed. Oil supply, wiring, the timing mechanism and the camshaft actuator also need consideration.
Hyundai calls this component the CVVT oil control valve, or OCV. This guide focuses on the 2.0L Beta-engine Elantra sedan and identifies the factory specifications used for that application. A matching connector or a broad Elantra catalog heading is not enough to establish fitment for later engines.
Moderate: basic electrical checks, careful valve handling and accurate low-range torque.
About 45–90 minutes for an accessible valve replacement after diagnosis; testing or a stuck valve can take longer.
$40–$100 estimated for one aftermarket valve, the correct seal and minor supplies; tools and extra diagnosis are separate.
Featured oil-control valve
The supplied listing is A-Premium APTCV009, ASIN B091J1Z82R: one engine variable valve timing solenoid. Amazon identifies a two-pin electromagnetic valve with a steel housing; the manufacturer specifies 12 volts. Listed interchange references include 24355-23763, 24355-23770 and 24355-23800, also shown without hyphens in the catalog.
This valve meters engine oil for the intake-cam timing system. It is different from the camshaft position sensor, the camshaft timing actuator itself and the separate OCV filter. The advertised package quantity is one solenoid. Confirm the correct sealing O-ring is supplied or obtain it separately before opening the engine; do not assume a filter, filter gasket, wiring connector, oil or tools are included.

Compatibility: separate the engine from the model name
The manufacturer and supplied listing identify the following selected 2.0L gasoline applications. The repair discussion focuses on the 2007–2010 Elantra sedan; the other rows describe catalog coverage and need their own access and service information.
| Make and model | Listed years | Engine and selection restrictions |
|---|---|---|
| Hyundai Elantra sedan — guide scope | 2007–2010 | 2.0L Beta four-cylinder with CVVT; confirm VIN, original valve and emissions configuration. |
| Hyundai Elantra — broader catalog family | 2003–2012 | Selected 2.0L CVVT applications only. Earlier emissions variants and later body styles require separate checking; the range does not include every Elantra engine. |
| Hyundai Tiburon | 2003–2008 | 2.0L four-cylinder listing; not the V6. Confirm CVVT and production details. |
| Hyundai Tucson | 2005–2009 | 2.0L gasoline four-cylinder; not the V6 or diesel. |
| Kia Soul | 2010–2011 | 2.0L gasoline four-cylinder only. |
| Kia Spectra / Spectra5 | 2004–2009 / 2005–2009 | 2.0L gasoline four-cylinder; verify body and production details. |
| Kia Sportage | 2005–2010 | 2.0L gasoline four-cylinder; not the V6 or diesel. |
Hyundai introduced a different 1.8L engine in the U.S. 2011 Elantra sedan, replacing the earlier 2.0L Beta. Do not buy this valve for a 2011–2012 sedan merely because the seller’s broader family range ends in 2012. Elantra Touring is a separate body/application that must be selected correctly. On older Elantras, confirm CVVT equipment rather than assuming every 2.0L version is identical.
Before ordering, compare the original interchange number, connector keying, terminal count, mounting ear and valve body with the replacement. Verify the vehicle’s actual engine, especially if it has been replaced. Neither a photograph nor the listing’s model-year range substitutes for the exact configuration check.
Diagnosis before replacement
1. Save codes and describe when the fault occurs
Record stored and pending codes, freeze-frame data and any recent repairs before erasing information. Note whether the roughness appears after a cold start, at hot idle or during acceleration. A recent timing-belt or cylinder-head repair is relevant to a correlation fault. P0011 concerns the timing system’s performance; P0016 compares crankshaft and camshaft position. Neither identifies a failed valve by itself.
Misfires, ignition problems and air leaks can also cause rough running. Keep other codes in the diagnostic record instead of treating every symptom as an OCV issue. If the engine stalls repeatedly or runs severely rough, arrange diagnosis without continuing normal road use.
2. Check oil condition and the electrical connection
Check oil level using the owner’s manual method and review the service history. The system relies on a clean, correctly supplied oil circuit. An oil-pressure warning, obvious contamination or abnormal mechanical noise changes the job from a routine valve swap to investigation of the underlying cause. Use the oil grade and quality required for the actual vehicle; additives and heavier oil are not a substitute for diagnosis.
With ignition off, inspect the two-pin connector for corrosion, bent terminals, oil contamination or a broken latch. Look for stretched, chafed or repaired wiring nearby. Pull on the connector housing when disconnecting it, never on the wires. Correct a damaged circuit before condemning a mechanically sound valve.
3. Measure resistance under the right conditions
The Elantra HD factory specification is 6.9–7.9 ohms at 20°C (68°F). With ignition off and the connector disconnected, measure across the valve’s two terminals. Make clean contact without spreading the terminals, and account for meter-lead resistance. A hot engine is not the specified test temperature, so let the component cool before comparing the reading.
An open circuit or clearly shorted coil supports an electrical failure diagnosis. A reading in range only shows that the coil passes that check; it does not prove the valve moves freely or that the engine’s oil passages and camshaft actuator work correctly. Use the matching circuit chart for harness tests rather than guessing pin functions or a universal voltage reading.
4. Check operation before replacing a working valve
Hyundai bulletin 09-EM-002 describes inspecting the OCV when diagnosing rough idle, poor acceleration and timing-related faults. It calls for resistance and movement checks and says a normally operating valve should not be replaced merely because the symptoms exist. Contamination can interfere with movement.
The bulletin’s powered bench test needs suitable isolated connections because the terminals are close together and can short. Leave that test to someone equipped to perform the complete procedure safely; do not improvise loose battery wires or energize the connected vehicle harness. A Hyundai-capable scan tool and the applicable diagnostic routine can help a technician distinguish a command problem from an oil-flow or mechanical problem.
Tools, parts and supplies
The linked products below are individual tool choices, not a claim that one kit fits every fastener on every listed vehicle. Match the actual socket size and drive before beginning. No jack is required for the top-of-engine valve work described here, and an oil change is a separate service if diagnosis calls for it.
| Tool or Supply | Exact Product | Product Link | Purpose and Selection Check |
|---|---|---|---|
| Metric sockets, extensions and ratchets | DEWALT DWMT73803, 168-piece mechanic’s set | View metric sockets, extensions and ratchets | Use a securely fitting metric socket and suitable extension for the actual retaining fastener. Do not infer socket size from bolt thread size. |
| Low-range torque wrench | EPAuto 1/4-inch, 20–200 in-lb (2.26–22.6 N·m) | View low-range torque wrench | Covers the identified 9.8–11.8 N·m valve-bolt range. Use a matching-drive socket and keep inch-pounds distinct from foot-pounds. |

| Conditional OCV filter and gasket | Engine-specific separate filter and new filter gasket | Select by vehicle specification | Only if diagnosis calls for filter service. This is not an assumed part of the featured package or the valve-only replacement. |
| Optional advanced diagnostic equipment | Hyundai-compatible bidirectional scan equipment and service test connections | Select by vehicle specification | Verify the exact functions for the vehicle. The basic reader above does not replace these capabilities. |
DIY versus professional cost
These are estimates for planning, not live Amazon prices or guaranteed repair quotes. A budget aftermarket valve may fall around $30–$70, with about $10–$30 for the correct seal and small supplies. If you already own the tools, a straightforward DIY parts-and-supplies budget is approximately $40–$100. Buying suitable sockets, a low-range torque wrench, meter and code reader can add roughly $100–$300.
For professional work, allow approximately $50–$150 for parts and supplies plus 0.5–1.5 hours at an illustrative labor rate of $120–$200 per hour: roughly $110–$450 before tax. Diagnostic time, a broken connector, a stuck valve, oil service or mechanical timing repairs are additional. Ask the shop to distinguish diagnosis from the labor charge for replacing the part.
DIY makes sense when the fault has been identified, the valve is accessible, the connector and fastener are intact, and you can tighten the bolt accurately. A shop is the better choice when the circuit requires advanced testing, the valve breaks or binds, or timing codes remain after oil and electrical checks.
Replacement overview for the Elantra 2.0L
The factory illustrations identify the externally mounted OCV and its retaining bolt. The torque below comes from the 2007 Elantra 2.0L specification and is also shown in the 2008 installation information. This is a valve-only overview; cylinder-head, timing-belt and separate filter work are different procedures.
1. Prepare the work area and identify the correct component
Save the diagnostic record, switch off the ignition, remove the key and let the engine cool. Locate the OCV using the engine diagram and compare its connector and mounting flange with the replacement. Distinguish it from the nearby oil-temperature and coolant-temperature sensors. Arrange lighting and tool access before opening the oil passage.
If an engine cover obstructs access, release its actual fasteners without forcing the cover or leaning on wiring. Confirm that the valve can withdraw along its axis with nearby hoses and connectors clear. Stop if access would require opening coolant or fuel connections; obtain the procedure for that exact configuration before expanding the repair.
2. Clean, disconnect and remove the retaining bolt
Remove loose dirt from around the mounting area while the old valve still seals the opening. Place a wipe below it to catch residual oil. Release the electrical latch and disconnect the plug carefully. Support the valve as you remove its retaining bolt, keeping the fastener where it cannot drop into the engine bay.
3. Withdraw the valve without damaging it
Withdraw it carefully, controlling the main body rather than pulling on the connector or clamping the thin sleeve. Hyundai cautions against holding the OCV sleeve during service and against reusing a dropped valve. Do not use the valve as a handle for moving engine components. If it binds, stop rather than pry against the aluminum housing or break the valve apart.
Inspect the removed component and its seal, and make sure no broken seal material remains at the opening. Keep the bore protected from dirt without stuffing material into it. Sludge, metal or damaged internal parts call for further diagnosis. Preserve the old valve for comparison and for the technician if additional investigation is needed.
4. Prepare the replacement and seat it correctly
Compare the old and new valve’s flange, connector and sealing arrangement. Use the correct undamaged new O-ring, with a light film of clean specified engine oil where required for seal installation. Keep the valve clean and do not apply gasket-maker to its oil openings. Insert it squarely and confirm the flange seats correctly; the retaining bolt should not be used to drag a misaligned valve into the bore.
5. Tighten and reconnect
Start the retaining bolt by hand to avoid cross-threading. Tighten it to 9.8–11.8 N·m (7.2–8.7 lb-ft) for the identified Elantra 2.0L installation. A low-range wrench is appropriate; a large wheel-fastener wrench may not measure this torque accurately. Reconnect the plug until its lock engages and route the harness clear of hot or moving components.
Reinstall any cover or access item removed, using its proper mounting arrangement. Check that no wipe, loose fastener or tool remains in the engine bay. Recheck engine oil level if oil was lost; do not overfill.
6. Verify the result
Start the engine while keeping clear of rotating components. Look for an oil leak around the valve and listen for unusual mechanical noise. Shut down immediately for leakage, an oil-pressure warning or severe roughness. After a stable idle and inspection, clear the recorded codes and check whether they return.
Road-test only if the vehicle operates safely, then scan again and inspect the valve area after the engine cools. An intermittent fault may need the original temperature and load conditions to recur. If P0011 or P0016 returns, continue the diagnosis instead of repeatedly replacing the same part. Oil supply, wiring, the actuator and mechanical timing remain possible causes.
Common mistakes
- Buying by the Elantra name while overlooking the engine, body style or emissions configuration.
- Treating P0011 or P0016 as a guaranteed solenoid failure.
- Testing coil resistance while connected to a powered circuit or comparing a hot reading with the 20°C specification.
- Clamping the sleeve, pulling on the electrical connector or installing a valve that was dropped.
- Reusing a damaged seal or forcing a valve into place with its mounting bolt.
- Applying the separate OCV-filter torque to the much smaller valve-retaining bolt.
- Adding sealant or fibers to the engine’s oil passage.
- Clearing codes before saving evidence, or considering one smooth idle a complete diagnosis.
Frequently asked questions
Are OCV, VVT solenoid and CVVT valve the same part here?
They describe this oil-control function in this application. They do not refer to the separate camshaft sensor or the mechanical camshaft timing actuator. Check the actual part and connector before ordering.
Can a valve pass resistance testing and still cause trouble?
Yes. Coil resistance does not establish free movement or correct oil flow. A complete diagnosis considers the command, valve response, oil circuit and timing mechanism.
Should I replace the valve if cleaning makes it work?
Hyundai’s inspection bulletin advises against replacing an undamaged valve that operates normally after the appropriate inspection and contamination correction. Find the source of contamination and verify the fault is resolved. Do not treat cleaning as a repair for a failed coil or damaged component.
Must I change the separate filter at the same time?
Not automatically. The separate OCV filter is a diagnostic consideration and has its own sealing and tightening requirements. If it is serviced, the factory instruction calls for a new filter gasket. It is not included in this valve-only procedure.
Will this fix a timing-belt or camshaft actuator problem?
No. A working replacement valve cannot correct incorrect mechanical timing or a damaged actuator. Recent timing work, persistent correlation faults and abnormal noise should change the diagnostic direction.
Can I use it in a later 1.8L Elantra?
This page does not establish that fitment. The later 1.8L engine uses a different system and requires its own application-specific valve selection.
