Throttle body replacement on a 2010 Chevrolet Camaro SS with the naturally aspirated 6.2L V8 may be appropriate after diagnosis of reduced engine power, erratic idle or poor accelerator response. Relevant codes include P1516, concerning throttle actuator performance, and P2135, concerning agreement between the two throttle-position signals. A warning or code does not prove that the assembly is defective. Low voltage, damaged wiring, poor connections and air leaks need attention before a new part is installed.
This guide follows GM’s 2010 6.2L procedure for the L99/LS3 engine family. It includes the replacement seal, duct clamps and scan-tool idle-learning method. The featured product has additional catalog applications, but this article does not extend the Camaro instructions to every Corvette, Caprice or Pontiac in the listing.
Moderate; enhanced scanner needed
1–2 hours after diagnosis
$95–$170, body and gasket
Allow extra time for diagnosis and learning if the old throttle was heavily contaminated. These estimates assume an original intake arrangement and undamaged hardware. An aftermarket intake, modified calibration or supercharger conversion requires its own compatibility assessment.
Featured throttle-body assembly
A-Premium APTHB067, ASIN B098JXNTVC, is one aluminum electronic throttle body with its throttle-position sensor and a six-terminal connection. The exact listing says no gasket and no separate idle-air-control valve are included. References include GM 12605109 and 19420707; cross-check the original assembly and current application catalog.
Buy a matching new gasket separately and compare the delivered part before disassembly. Check the mounting pattern, connector keying, inlet shape and seal location. The same terminal count does not prove electrical compatibility. Do not adapt a wrong plug or change the factory stop to compensate for a mismatched unit.

Diagnosis before disassembly
Read stored and pending faults and save the freeze-frame information. Note whether the concern appeared after intake work, a weak battery, cleaning or another repair. Inspect the air duct for loose clamps, cracks and poor seating, and check the crankcase-vent connection. An air-path problem can remain after a perfectly good new throttle body is installed.
With the ignition off, inspect the electrical latch, harness strain and terminal condition. Corrosion, a backed-out terminal or resistance in a circuit can interrupt the signal. GM’s P2135 diagnosis compares two position signals; it is not a command to replace one sensor. The factory assembly’s position sensors are not serviced separately in the cited diagnostic information.
Resolve battery or charging problems and relevant reference-voltage faults before proceeding. With suitable equipment, compare commanded operation with actual response and follow the circuit tests for the reported code. Do not apply battery voltage to the connector, pierce insulation at random or force the plate to test the motor. If the evidence is incomplete, a diagnostic appointment is usually cheaper than several speculative parts.

| Enhanced scanner — conditional selection | FOXWELL NT510 Elite, GM software version | View product | Listing identifies GM coverage and throttle relearn. Confirm 2010 Camaro 6.2L Idle Learn Reset and TB Idle Airflow Compensation support before purchase. A general TPS-reset label alone is insufficient. |
| Wheel chocks | Fasmov solid-rubber wheel chocks, two-pack with handles | View product | Secure the parked car on level ground. Match tire size and follow the chock instructions; this underhood repair does not require lifting. |
Arrange compatible scan-tool access before taking the car apart. The FOXWELL link identifies a GM-specific product, but final function coverage must be confirmed for this engine and software version. The required functions are named below. If your tool cannot perform them, have an equipped shop complete setup; the basic AD310 gathers evidence but does not substitute for enhanced functions.
Estimated DIY and professional cost
| Expense | DIY allowance | Professional allowance |
|---|---|---|
| Throttle body and seal | $95–$170 | $130–$300 |
| Small consumables | $5–$15 | $10–$30 |
| Tools already owned | $0 additional | Included in labor |
| Tools / enhanced scanner if needed | $100–$350+ | No personal tool purchase |
| Replacement and setup labor | Your time | $120–$300 |
| Subtotal with existing equipment | $100–$185 | $260–$630 |
These are US planning estimates, not live retail prices or guaranteed quotes. Diagnosis, tax, towing and connector repairs are additional. Ask whether a shop includes the seal and learning procedure. If you must buy an enhanced scanner for this one job, compare the complete DIY cost with a written quote.
Replacement steps: 2010 Camaro SS 6.2L
1. Prepare and identify the parts. Save the diagnostic report, confirm the replacement and gasket, and photograph the duct routing. Secure the parked vehicle, cool the engine and switch the ignition off. Prevent anyone from operating the key while the intake is open. The cited procedure removes the throttle separately; removing the fuel rail or manifold is unnecessary.
2. Remove the resonator and outlet duct. Disconnect the crankcase-vent tube from the resonator using its intended release. Loosen the two duct clamps and withdraw the duct without loading the air-cleaner housing or wiring. Inspect its ends and underside. Protect exposed openings with a clean cover that cannot fall inside.
3. Remove the assembly. Release the electrical connector, remove the four mounting bolts and lift off the housing. Discard the old single-use gasket. Keep the replacement clean while inspecting the mating surfaces. Do not drop the assembly, insert a screwdriver into the bore or immerse its electronics in solvent.
4. Install the gasket and throttle body. Clean accessible mating surfaces without gouging them or pushing debris into the manifold. Align the new gasket’s locating tab with the manifold notch. Seat the housing squarely, start the bolts by hand and tighten to 12 N·m (106 in-lb). No additional angle stage is specified here.
5. Restore the intake. Reconnect and lock the electrical plug. Remove every temporary cover, seat both duct ends and tighten the two clamps to 4 N·m (35 in-lb). Restore the crankcase-vent connection and secure disturbed wiring. A folded duct edge can leak even with a tight clamp, so inspect the entire joint.
6. Complete scan-tool learning. Resolve active faults first. GM’s reset has a code-inhibit list covering airflow, temperature, fuel, misfire, reference-voltage and throttle faults. With the car stationary, ignition ON and engine OFF, select Idle Learn Reset in Module Setup. Start the engine and monitor TB Idle Airflow Compensation: the expected value is 0% with normal idle. Clear DTCs as directed and complete the diagnostic verification that led to replacement. Do not erase an unresolved fault simply to force the routine.
7. Verify the result. Confirm stable idle, normal pedal response and no new intake noise. Read current and pending codes again. Road-test only when the car is controllable, then recheck the original complaint and disturbed joints. An empty code list immediately after clearing is not enough to establish a successful repair.
GM also describes an adaptive route without commanding the reset, but it still calls for scan monitoring and can require multiple cycles. This guide uses the reset-and-parameter-check method above. If the function is unavailable or the compensation value and idle fail the check, return to diagnosis rather than improvising a pedal sequence.
Common mistakes
Reusing a seal, misaligning its locating tab or leaving the connector partly latched can create a new fault. Remove the discarded seal from the work area so it cannot be reused accidentally. Do not add RTV to the molded gasket; the cited procedure calls for a new correctly seated seal.
Use inch-pound settings accurately. The clamps require less torque than the body bolts, and both settings are far below wheel-fastener torque. A large wrench used below its rated range is unsuitable. Keep the socket aligned and stop if a bolt binds before the housing seats.
Do not declare the job finished because the engine starts. The ECM retains airflow learning from the previous assembly, and a clean replacement can flow differently. Learning and verification are part of the repair. Keep the old part and purchase information until the original fault has been checked under the conditions that previously produced it.
Frequently asked questions
Does this fit a V6 Camaro? This product selection and procedure concern the identified V8 applications. The 3.6L Camaro is outside this guide’s scope.
Can I replace only the position sensor? This guide installs the complete assembly. GM describes its sensors as non-serviceable separately; diagnose their circuits before deciding what needs replacement.
Does the package include the gasket? The exact listing says it does not. Obtain the matching new seal before starting and align its tab during installation.
Can a generic reader perform the reset? Reading or clearing codes is a different capability. Confirm GM Idle Learn Reset and the airflow-compensation parameter before relying on a scanner.
Can I use these instructions for a Corvette? Shared catalog fitment does not establish identical access, fasteners or setup. Use the exact model-year procedure.
For an older GM truck application, see our 2004 Silverado 5.3L VIN T guide. Its assembly, coolant connection and torque values differ.
