⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Allow the engine to cool before opening the oil drain plug or removing any components.

Symptoms

•Check engine light illuminated
•Rough idle or fluctuating RPM
•Loss of power during acceleration
•Increased fuel consumption
•Engine stalling or hesitation

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to confirm P0011 and check for any related codes.
2
Inspect the engine oil level and condition; low or dirty oil can affect VVT operation.
3
Check the VVT solenoid for proper operation by testing its electrical connections and functionality.
4
Inspect the timing chain/belt for wear or misalignment.
5
Verify that the oil control valve (OCV) is functioning correctly and is not clogged.
6
Examine the camshaft timing alignment with the manufacturer’s specifications.

Solution
