DESCRIPTION
The Variable Valve Timing (VVT) system adjusts the intake valve timing to improve driveability. The engine oil pressure turns the VVT controller to adjust the valve timing.
The camshaft timing oil control valve assembly is a solenoid valve and switches the engine oil line. The valve moves when the ECM applies 12 V 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.

P0010 |
Open or short in camshaft timing oil control valve (for intake camshaft) circuit (1 trip detection logic) |
|
MONITOR DESCRIPTION
This DTC is designed to detect open or short in the camshaft timing oil control valve assembly (for intake camshaft) circuit. If the camshaft timing oil control valve's duty-cycle is excessively high or low while the ignition switch is ON or the engine is running, the ECM will illuminate the MIL and set the DTC.

PROCEDURE
1. |
PERFORM ACTIVE TEST USING TECHSTREAM (OPERATE CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY) |
(a) Connect the Techstream to the DLC3.
(b) Start the engine.
(c) Turn the Techstream on.
(d) Turn the A/C switch on.
(e) Enter the following menus: Powertrain / Engine / Active Test / Control the VVT Linear (Bank 1).
(f) Check the engine speed while operating the camshaft timing oil control valve assembly (for intake camshaft) using the Techstream.
OK:
