P0010 on Toyota by model: symptoms, diagnosis and fix
The VVT-i camshaft timing oil control valve (OCV/spool valve, PN 15330-22030 on 1ZZ-FE) sticks or clogs with oil varnish on high-mileage Corollas, so the intake cam phaser can no longer be controlled. This sets P0011 'A Camshaft Position Timing Over-Advanced (Bank 1)' (or P0010/P0016) and can cause rough idle, hesitation and a rattle at start. Low or dirty engine oil, and the small OCV filter screen clogging, are the usual root causes.
Common Symptoms
- Check engine light with P0011
- Rough or unstable idle
- Hesitation or reduced power
- Start-up rattle from cam phaser
How to Fix
Check engine oil level/condition first (VVT faults often stem from low or degraded oil). Remove the camshaft timing oil control valve, clean the OCV and its filter screen; if the plunger is sticky or the solenoid fails a resistance/actuation test, replace it. OEM PN 15330-22030 (fits 2000-2008 Corolla 1ZZ-FE; also Celica/Matrix/MR2), roughly $50-90; Denso/Standard aftermarket cross-references available. Clear codes and verify cam timing response after replacement.

Frequently asked questions
What does P0010 mean on a Toyota?
P0010 stands for "Intake Camshaft Position Actuator Circuit (Bank 1)." This code points to an electrical problem in the intake camshaft position actuator (variable valve timing) circuit on Bank 1. The computer controls an oil-fed solenoid to advance or retard the intake camshaft for better performance and efficiency, and it has detected the solenoid circuit is open, shorted, or out of range. This is usually an electrical or solenoid fault rather than a mechanical timing problem, though oil-related issues can play a role. You may notice rough running, reduced power, or lower fuel economy. On Toyota it is documented across 1 model: Corolla.
What are the most common causes of P0010?
The most common causes of P0010 are: Faulty intake camshaft (VVT) oil control solenoid, Damaged, corroded, or loose wiring/connector at the solenoid, Open or short in the actuator circuit, Low or dirty engine oil restricting the solenoid, Clogged solenoid screen or oil passage, Poor electrical ground, Failed PCM/ECM (less common). The specific cause varies by vehicle.
How much does it cost to fix P0010 on a Toyota?
Published repair estimates on Toyota range from $90 to $300 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
