OBD2 P0016
OBD2P0016
Diagnostic Trouble Code· Standard OBD-II fault code read from the vehicle's onboard diagnostics.
What it means
Crankshaft Position - Camshaft Position Correlation.
Severity
highNot recommended to drive as the engine can stall at any time.
Summary
P0016 indicates a correlation issue between the crankshaft position sensor (CKP) and camshaft position sensor (CMP) on bank 1 sensor A. This code suggests that the PCM is not receiving proper signals from these sensors to synchronize engine timing.
Symptoms
- Engine runs poorly
- Engine cranks but does not start
- Check Engine Light illuminated
Common Causes
- Faulty cam or crank sensor
- Open or shorted circuit in CKP/CMP
- Timing belt/chain out of time
- Slipped/broken tone ring on camshaft/crankshaft
- Problem with VVT system
- PCM malfunction
Diagnosis
- Visually inspect sensors and connections for damage or corrosion
- Test sensor output using an ohmmeter or multimeter
- Check sensor circuits for continuity and proper voltage
Fixes
- Replace faulty CKP/CMP sensor(s)
