Toyota Yaris Corolla 2008,2009,2010,2011 1NZ (FE) fault code P0010 camshaft position ''A'' Actuator circuit (bank 1)
Hint
This DTC relates to the oil control valve (OCV)
this DTC is designed to detect opens or shorts in the camshaft oil control valve (OCV) circuit.If the OCV's duty-cycle is excessively heigh or low while the engine running, the ECM will illuminate the MIL and set the DTC.
The VVT (variable valve timing) system adjusts the intake valve timing to improve the driveability. The engine oil pressure tums the camshaft actuator to adjust the valve timing. The OCV is a solenoid valve and switches the engine oil line. The valve moves when the ECM applies the 12 volts to the solenoid. The ECM changes the energizing time to the solenoid (duty-cycle) in accordance with the camshaft position, crankshaft position, throttle position etc.
Inspection Procedure
Hint :
Read freeze frame data using a Techstream Freeze fram data record the engine condition when malfunctions are detected. 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 learn or rich, and other data, from the time the malfunction occurred.
Procedure
1. Check DTC (opreate OCV)
(a) Connect a Teachstream to the DLC3.
(b) Turn the ignition switch ON and turn the tester aon.
(c) Clear DTC,s after recording the freeze frame data and DTC,s.
(d) Start the engine.
(e) Allow the engine to idle and check for DTCs.
(f) Check that p0010 is present.
ok:
P0010 is present.
NG - CHECK FOR INTERMITTENT PROBLEMS
ok - continue to next step.
2. Inspect camshaft timing oil control valve assembly
(a) Disconnect the C24 OCV connector.
(b) Disconnect the C20 ECM connector.
(c) Check the resistance.
