Common Symptoms
- Check Engine Light illuminated
- Rough idle or engine misfire
- Hard starting or extended cranking
- Poor fuel economy
- Reduced engine power or performance
- Engine may stall at idle
Most Likely Root Causes
- Stretched or worn timing chain or belt
- Failed or failing camshaft position sensor
- Failed or failing crankshaft position sensor
- Low engine oil level or incorrect oil viscosity
- Faulty variable valve timing solenoid or actuator

Component Location
Crankshaft position sensor is typically mounted near the crankshaft pulley; camshaft position sensor is located on the cylinder head or timing cover.
Manufacturer Notes
Some manufacturers are particularly sensitive to oil viscosity and condition affecting variable valve timing system correlation errors.
