P0016 Crankshaft/Camshaft Position Correlation (Bank 1 Sensor A)
What it means
The crankshaft and camshaft sensor signals don't line up as expected, so cam timing appears off relative to the crank.
Severity: High
Can I drive it? Drive as little as possible. A stretched or jumped timing chain/belt can cause serious engine damage.
Common causes (most likely first)
- Stretched timing chain or worn guides/tensioner
- Faulty VVT solenoid or phaser
- Low/dirty oil
- Faulty cam or crank sensor
Likely fixes
- Check oil
- Check sensors and VVT solenoid
- Inspect/replace timing chain components
