P0010 | Camshaft Position "A" Actuator Circuit (Bank 1) |
DESCRIPTION
Tech Tips
This DTC relates to the oil control valve.
The Variable Valve Timing (VVT) system includes the ECM, intake camshaft timing oil control valve assembly and VVT controller. The ECM sends a target duty-cycle control signal to the intake camshaft timing oil control valve assembly. This control signal regulates the oil pressure applied to the VVT controller. Camshaft timing control is performed according to engine operating conditions such as the intake air volume, throttle valve position and engine coolant temperature. The ECM controls the intake camshaft timing oil control valve assembly, based on the signals transmitted by several sensors. The VVT controller regulates the intake camshaft angle using oil pressure through the intake camshaft timing oil control valve assembly. As a result, the relative positions of the camshaft and crankshaft are optimized, the engine torque and fuel economy improve, and the exhaust emissions decrease under overall driving conditions. The ECM detects the actual intake valve timing using signals from the camshaft and crankshaft position sensors, and performs feedback control. This is how the target intake valve timing is verified by the ECM.

CAUTION / NOTICE / HINT
Tech Tips
Read freeze frame data using the GTS. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
PROCEDURE
PERFORM ACTIVE TEST USING GTS (OPERATE CAMSHAFT TIMING OIL CONTROL VALVE)
Connect the GTS to the DLC3.
Start the engine and turn the GTS on.
Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the VVT System (Bank 1).
Check the engine speed when the oil control valve is operated using the GTS when the engine coolant temperature is 50°C (122°F) or less.
Tech Tips
When performing the Active Test, the air conditioning should be on.
Make sure the engine coolant temperature when the engine is started should be 30°C (86°F) or less.
