What is P0010?
The generic code P0010 is defined as “‘A’ Camshaft Position Actuator Circuit (Bank 1).”
This error code tells you that the powertrain control module (PCM) or engine control module (ECM) has detected a problem with your engine’s Variable Valve Timing (VVT) solenoid.
The Variable Valve Timing (VVT) system helps improves engine performance and fuel economy by regulating the opening and closing of the intake and exhaust valves, which are controlled by the camshaft. The PCM adjusts camshafts through the use of Variable Valve Timing solenoid valves.
A P0010 code means there’s an issue with the variation in the mechanical timing between the Bank 1 camshaft and crankshaft.
Cam timing issues typically occur during higher revolutions per minute (RPM) of the engine. This is when the powertrain control module tries to adjust valve lift during higher speeds.
Note: The Variable Valve Timing solenoid valve is also known as the camshaft actuator solenoid valve or oil control valve (OCV.)
How Does The Camshaft Actuator Solenoid Operate?
Your vehicle’s ECM or PCM is designed to send a pulse width signal to the solenoid, allowing it to turn the solenoid rapidly on and off. The longer the solenoid is on during each pulse, the more oil pressure is supplied to the actuator.
The cam sensor (CMP) regulated on the Bank shuts the feedback loop. This way, the ECM or PCM can detect the camshaft advancement needed (depending on engine load, speed, etc.) It’ll also determine how well the solenoid is regulating the camshaft.
