OBD2P0365
Diagnostic Trouble Code· Standard OBD-II fault code read from the vehicle's onboard diagnostics.

What it means

Camshaft Position Sensor 'B' Circuit.

Severity

moderateCan drive, but performance will be poor and fuel efficiency may decrease.

Summary

P0365 indicates a malfunction in the camshaft position sensor B circuit for bank 1 of your 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 resistance values.
  4. Use an oscilloscope to observe waveform patterns near the sensor and PCM connector.

Fixes

  • Replace defective camshaft or crankshaft sensor if necessary.
  • Repair or replace open or shorted wiring as needed.
