OBD2 P0017

OBD2P0017
Diagnostic Trouble Code· Standard OBD-II fault code read from the vehicle's onboard diagnostics.

What it means

Crankshaft Position - Camshaft Position Correlation.

Severity

moderateCan drive, but performance issues may occur and the vehicle should be inspected soon.

Summary

Code P0017 indicates a correlation issue between the crankshaft position and camshaft position sensor in bank 1, specifically sensor B. This code suggests that there is a problem with how these sensors are communicating timing information to the PCM.

Symptoms

  • Engine runs poorly
  • Engine cranks but does not start
  • Check engine light illuminated

Common Causes

  • Faulty cam or crankshaft position sensor
  • Open or shorted circuit in the cam or crankshaft sensor wiring
  • Timing belt/chain out of sync
  • Slipped or broken tone ring on cam or crankshaft
  • Problem with variable valve timing (VVT) system
  • PCM malfunction

Diagnosis

  1. Visually inspect sensors and connections for damage or loose wires.
  2. Test sensor output using an ohmmeter or multimeter to check resistance and voltage readings.
  3. Check sensor circuits for continuity between the PCM and the sensors.
  4. Use an oscilloscope to test synchronization of camshaft and crankshaft sensors.

Fixes

  • Replace faulty cam or crankshaft position sensor
  • Repair or replace timing belt/chain if out of sync
