Error code

OBD2 P0369

OBD2P0369
Diagnostic Trouble Code· Standard OBD-II fault code read from the vehicle's onboard diagnostics.

What it means

Camshaft Position Sensor 'B' Circuit Intermittent.

Severity

moderateCan drive, but performance will be affected.

Summary

P0369 indicates an intermittent issue with the camshaft position sensor B circuit on bank 1 of your vehicle's engine.

Symptoms

  • Hesitation upon acceleration
  • General lack of engine performance
  • Diminished fuel efficiency
  • Overheated catalytic converter due to timing issues
  • Spark detonation (backfire) when decelerating
  • Spark knock (pinging) when accelerating

Common Causes

  • Defective camshaft sensor or crankshaft sensor
  • Open or shorted wiring to the camshaft sensor
  • Corroded or fluid-soaked connector/camshaft sensor
  • Faulty PCM or PCM programming error

Diagnosis

  1. Perform a visual inspection of all system-related wiring harnesses and connectors.
  2. Test voltage and ground signals at the camshaft sensor using a digital volt/ohmmeter (DVOM).
  3. Disconnect and test the camshaft sensor for internal resistance values.
  4. Use an oscilloscope to observe waveform patterns from the camshaft sensor and PCM connector.

Fixes

  • Replace defective camshaft or crankshaft sensor if necessary.
  • Repair or replace open/shorted wiring or connectors.
