Estimated Time

4-8 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

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

Symptoms

•Check engine light illuminated
•Rough idle or engine stalling
•Loss of power during acceleration
•Poor fuel economy
•Engine noise at startup
•Increased emissions

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to confirm P0016 and check for additional codes.
2
Inspect the timing belt/chain for proper tension and any visible wear or damage.
3
Check the camshaft and crankshaft position sensors for proper operation and wiring integrity.
4
Verify the alignment of the camshaft and crankshaft timing marks according to the manufacturer's specifications.
5
Measure engine oil pressure to ensure that it meets the manufacturer's requirements.
6
Inspect the Variable Valve Timing (VVT) solenoid for proper function and oil flow.

Solution
