Variable valve timing solenoid replacement may be considered for rough idle, weak acceleration or camshaft-timing faults such as P0011 (intake timing over-advanced/system performance) and P0012 (intake timing over-retarded) on the 2010–2011 Hyundai Accent 1.6L. The featured valve is also cataloged for the 2010 Kia Rio and Rio5 1.6L. Symptoms and codes alone do not prove the oil-control valve has failed: oil supply, wiring and mechanical timing can produce similar complaints.
This guide focuses on buying the correct single solenoid, diagnosing the cause and planning a clean installation on the Accent application. A replacement valve cannot correct inadequate oil pressure or damaged timing components.
Intermediate diagnosis; careful basic mechanical work once the fault is isolated.
Planning estimate: 1–2 hours for an accessible valve, plus diagnosis. Corrosion, damaged wiring or additional access work can add time.
Planning allowance: $30–$90 for one aftermarket solenoid, excluding tools, oil service, tax and shipping.
Park on level ground, apply the parking brake and allow the engine to cool. Keep keys away from the ignition during removal, and keep hands clear of belts and electric fans. Stop running the engine if the oil-pressure warning stays on, severe knocking develops or oil leaks onto hot parts. Never probe the control circuit with an unfused jumper or apply battery power to the vehicle harness. Protect the open valve bore from dirt, cloth fibers and dropped hardware.
Application overview
The relevant Accent is the older MC/Alpha 1.6L application. Market naming and registration dates can overlap with a newer-generation Accent, so a badge or registration year alone is insufficient. Compare the VIN-based parts catalog, the installed valve reference, connector keying and mounting arrangement before ordering. The two-pin electrical connection is a useful comparison point, but does not establish compatibility by itself.
The table below preserves the featured item’s catalog coverage. Kia entries describe product fitment; they do not make Accent access instructions or fastener settings universal. Do not extend this listing to an earlier Accent or a 2011 Kia just because another supplier sells a similarly named solenoid.
| Make / model | Model years | Engine | Body / selection checks |
|---|---|---|---|
| Hyundai Accent | 2010–2011 | 1.6L inline-four | Seller specifies hatchback and sedan. Match the MC/Alpha application and 24355-26800 cross-reference; confirm the exact market/VIN. |
| Kia Rio | 2010 | 1.6L inline-four | Seller specifies sedan. Verify installed valve and VIN; use Kia service information for removal and tightening. |
| Kia Rio5 | 2010 | 1.6L inline-four | Seller specifies hatchback. Do not assume later Rio5 coverage. |
The listing does not provide a separate transmission or drivetrain restriction. That omission is not proof of universal fit across markets, engine swaps or every production configuration.
Featured replacement solenoid
A-Premium engine variable valve timing solenoid, part APTCV066; ASIN B09Q8V2X59. The selected listing supplies one valve, not a pair. Listed cross-references include 24355-26800 / 2435526800, VTS1055 and 918-038. It is an electromagnetic, two-pin oil-control valve; the manufacturer lists a 12V application.
The package description does not separately promise a new mounting bolt, an external OCV filter, a filter gasket or an oil-change kit. Inspect the actual valve seal and included contents before dismantling the car. Keep the old part available until connector shape, mounting flange, overall insertion geometry and seal arrangement have been compared. Never force a mismatch into the head.

Warranty terms can differ by sales channel. Read the terms attached to the selected seller rather than assuming the manufacturer’s direct-store offer applies to this purchase.
Diagnose the cause before buying
Record the complaint
Note whether the fault appears cold, hot, at idle or under load, and whether it began after oil service or timing work. Save stored and pending codes and their freeze-frame information before disconnecting the battery. P0011 and P0012 describe timing behavior; they do not identify a failed replacement part. A flashing malfunction lamp or pronounced misfire warrants stopping the drive and investigating promptly.
Start with lubrication and the connector
Check the oil level by the owner’s-manual method and inspect its condition and service history. Correct a low level with the specified oil and investigate why it became low. Heavy sludge, metallic debris or an oil-pressure warning requires further diagnosis. Do not use an aggressive flush as a substitute for finding an oil-supply fault.
With the ignition off, inspect the connector latch, terminal condition and harness routing. Look for oil intrusion, pulled wires and rubbing near brackets. Repairing a connector can solve a circuit problem that a new valve would leave unchanged. Keep test probes from spreading female terminals.
Separate electrical failure from hydraulic response
Hyundai’s 09-EM-002 bulletin identifies the Accent MC Alpha 1.6L among its applications and directs technicians to test OCV operation before replacement. Its Denso coil reference is 6.9–7.9 ohms at 20°C / 68°F. Apply that reference only to the matching original supplier and test conditions; it is not an independently supplied resistance specification for APTCV066. A normal resistance reading does not prove that the valve moves freely or receives adequate oil.
A basic code reader cannot command the valve or prove camshaft response. If circuit checks are normal and timing faults return, a technician may need manufacturer-capable scan data, an actuator test and an oil-pressure/mechanical-timing assessment. Do not improvise a powered bench test without the correct isolated-terminal procedure.
Tools, parts and supplies
Buy only what you need. The specifications below describe the linked tools, not a universal fastener size or torque setting. Confirm access, load rating and actual fasteners on your vehicle before starting.
| Tool or supply | Exact product | Product link | Purpose and selection check |
|---|---|---|---|
| Metric sockets and hand tools | DEWALT DWMT73803, 168-piece mechanics tool set | View DEWALT DWMT73803, 168-piece mechanics tool set | Use a snug-fitting metric socket and short extension for the actual retaining bolt. Includes 1/4-inch sockets compatible with the torque wrench below; confirm the bolt head before selecting a socket. |
| Low-range torque wrench | TEKTON TRQ21101, 1/4-inch drive, 10–150 in-lb | View TEKTON TRQ21101, 1/4-inch drive, 10–150 in-lb | The verified 2010 Accent OCV mounting specification, approximately 87–104 in-lb, falls within this range. Use inch-pounds, not foot-pounds. This model is discontinued; check seller availability. |
| OBD-II code reader | Autel AutoLink AL319 | View Autel AutoLink AL319 | Reads generic engine codes, freeze-frame data and readiness. Record information before clearing. This is not a bidirectional Hyundai actuator-control tool. |
| Electrical diagnosis — optional | INNOVA 3320 auto-ranging digital multimeter | View INNOVA 3320 auto-ranging digital multimeter | For de-energized component resistance and appropriate circuit checks. Disconnect the valve for resistance testing; do not measure resistance on a powered circuit or force oversized probes into terminals. |
| Eye protection | DEWALT DPG82-11C Concealer clear safety goggles, one pair | View DEWALT DPG82-11C Concealer clear safety goggles, one pair | Wear when cleaning around the valve and handling oily parts. Keep solvents away from eyes and use ventilation required by any cleaning product. |
Application-specific materials: obtain the correct valve seal if it is not supplied or is damaged. Select oil and any filter by the exact vehicle’s specification. If separately servicing the OCV filter on the 2010 Accent, Hyundai calls for a new filter gasket; that filter operation has different access and torque requirements. These parts are not interchangeable with a universal O-ring assortment. Have clean, low-lint wiping material available and keep it outside the oil passage.
DIY versus professional cost
These are planning estimates in US dollars, not current retail prices or a shop quotation. They assume a confirmed solenoid fault and an otherwise serviceable engine.
| Cost item | DIY allowance | Professional repair allowance |
|---|---|---|
| Replacement valve | $30–$90 | $50–$160 depending on brand and shop sourcing |
| Small consumables / seal | $5–$25 | $10–$35 |
| Tools not already owned | $0–$250 for the selection actually needed | Normally included in labor rate |
| Replacement labor | Your time; approximately 1–2 hours | 0.5–1.5 hours at an assumed $100–$180/hour: $50–$270 |
| Diagnosis | Basic checks may use existing tools | Allow $100–$200 when separately billed |
| Estimated total | $35–$115 with tools owned; up to $365 buying tools | $210–$665 with the diagnostic allowance included |
Oil and filter service, wiring repair, restricted oil passages or internal timing work add cost. Ask a shop whether diagnosis is credited toward the repair and whether the quote includes a new seal and a post-repair leak/code check. A cheap valve is poor value if the real fault remains unresolved.
Replacement overview
1. Prepare and establish access
Save diagnostic information, switch the ignition off and let the engine cool. Identify the valve by its connector and installation location using the exact vehicle service information. On the Accent, the OCV mounts to the cylinder head. Do not confuse it with a camshaft-position sensor or start loosening timing hardware. Photograph the harness route before moving anything.
Remove only the covers or access pieces required for your configuration and retain their fasteners separately. Disconnect and isolate the negative battery cable before unplugging or removing the valve. If reaching the valve would require disturbing an engine mount, timing belt, fuel connection or other major assembly, stop and obtain the complete procedure for that work.
2. Clean before opening the oil passage
Wipe away loose contamination around the valve and its mounting area while it is still installed. Avoid pushing grit toward the bore. Release the connector by its latch and hold the connector body rather than pulling its wires. Brittle plastic needs patient handling; a broken latch can create an intermittent fault after the repair.
3. Remove and inspect the old valve
Support the valve while removing its retaining fastener, then withdraw it carefully along its bore. Do not bend the sleeve, lever against a sealing surface or use the plastic connector as a handle. Catch small oil drips and prevent any debris entering the opening. Account for the old seal before inserting the new part.
Inspect the removed valve and visible passage for contamination and damage. Metal particles, a damaged bore or a valve that cannot be removed without force calls for further assessment. Preserve evidence rather than washing everything away before the cause is understood.
4. Compare, seat and tighten
Compare the old and new valve’s flange, connector, seal and insertion length. Use the correct undamaged seal and the lubrication method specified for that seal. Do not add RTV or thread sealant to the oil-control passages. Seat the valve squarely without using the mounting bolt to drag it into an obstructed bore.
2010 Hyundai Accent 1.6L reference: Hyundai’s cylinder-head installation procedure specifies 9.8–11.8 N·m (7.2–8.7 ft-lb; approximately 87–104 in-lb) for the OCV mounting fastener. This is not the separate OCV filter’s tightening value. Use a calibrated low-range wrench and stop at the specified setting. For a 2011 Accent or a Kia application, obtain that vehicle’s applicable specification before tightening.
Keep the replacement clean and protect it from drops. Hyundai cautions against reusing a dropped OCV and against handling the valve by its sleeve. Cracked plastic or distorted mounting geometry is a reason to replace the damaged component, not compensate with extra bolt torque.
5. Reassemble and verify
Reconnect the electrical plug until its latch engages and restore every harness clip and removed access component. Reconnect the battery using the vehicle procedure. Remove tools and wiping material before starting. Run the engine outdoors or with proper exhaust extraction, keeping clear of moving belts and fans.
Check immediately for oil leakage at the valve and stop if a leak or oil-pressure warning appears. Recheck the oil level by the owner’s-manual method after shutdown. Once safe operation is established, clear recorded faults with the scan tool, road-test under appropriate conditions and check for returning pending or stored codes. A temporarily extinguished light alone does not prove the repair is complete.
Common mistakes
- Buying by a broad “Accent 1.6” description without checking the generation, year and valve cross-reference.
- Replacing the solenoid solely because P0011 or P0012 appears.
- Ignoring low oil, contamination or harness damage.
- Using a high-range wheel-lug torque wrench for the small OCV fastener.
- Confusing inch-pounds with foot-pounds, or applying the separate filter torque to the solenoid bolt.
- Leaving an old seal in the bore, pinching a new seal or contaminating an oil passage with towel fibers.
- Clearing codes before recording them, then skipping the leak check and follow-up scan.
Frequently asked questions
Is this the camshaft-position sensor?
No. The oil-control solenoid regulates oil flow for variable cam timing. A position sensor reports shaft position. Similar symptoms do not make the parts interchangeable.
Does one listing contain both intake and exhaust valves?
No. This selected ASIN describes one solenoid. Do not assume that photographs of other variations or a newer dual-CVVT engine apply.
Can cleaning replace diagnosis?
No. Cleaning can hide useful evidence and does not repair an open coil, damaged connector or worn timing mechanism. Follow the applicable inspection procedure and investigate contamination at its source.
Can I drive while the light is on?
The answer depends on the fault and symptoms. Stop for oil-pressure warnings, knocking, major leakage or a flashing malfunction lamp. A steady light still requires diagnosis; avoid treating the solenoid listing as permission to keep driving.
Do I need a jack for this guide?
No under-vehicle operation is included here. If your specific access procedure calls for lifting, use the vehicle’s approved lift and support points with suitable equipment; do not work under a vehicle held only by a jack.
