| Trouble Code (DTC) | P0016 |
|---|---|
| Official SAE Definition | Crankshaft Position – Camshaft Position Correlation (Bank 1 Sensor A) |
| Vehicle Subsystem | powertrain |
| Driving Severity | HIGH |
Observable Symptoms
- Long cranking time or no-start
- Metallic timing chain rattle on cold start
- Reduced power
Most Probable Root Causes
- Stretched timing chain or worn chain tensioner/guides
- Jumped timing belt tooth
- Slipped camshaft phaser
Step-by-Step Diagnostic Procedure
- Compare actual vs desired cam angle at idle
- Inspect timing chain stretch via tensioner protrusion or dual-channel oscilloscope
