⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Allow the engine to cool before opening any components.

Symptoms

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

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to confirm P0011 and check for 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 and electrical connection.
4
Inspect the timing chain/belt for wear and proper alignment.
5
Measure the camshaft and crankshaft position sensors' output with a multimeter.
6
Look for oil leaks around the VVT system components that could affect operation.

Solution
