Causes

  • Damaged or disconnected sensor wiring or connector (open, short to ground, short to battery)
  • Corroded or contaminated connector pins
  • Failed camshaft position sensor (Hall-effect or variable reluctance type)
  • Poor sensor reference voltage or ground from PCM
  • Damage from oil/heat/engine vibration
  • Faulty PCM or internal driver circuit (less common)

Symptoms

  • Malfunction Indicator Lamp (MIL) illuminated with P0365 stored
  • Engine may run rough, misfire, or idle poorly
  • Hard start or no-start conditions if signal absent
  • Reduced engine performance and fuel economy
  • Possible failed emissions or readiness monitors

What to check

  • Read and record freeze frame and live data, note engine rpm and other stored codes
  • Scan for related codes (cam/crank, bank 2 cam sensor, crankshaft position)
  • Visually inspect sensor, wiring and connector for damage, corrosion, oil ingress, or loose pins
  • Check battery voltage and PCM power/grounds before testing sensor
  • Backprobe sensor connector while cranking/running to observe signal
  • Compare live cam sensor B signal to cam sensor A and to expected behavior

Signal parameters

  • Hall-effect (common): square-wave digital pulse referenced to PCM supply (typically 0–5V logic). Expected switching between near 0V and near 5V synchronized to cam rotation.
  • Variable reluctance (VR) type: AC sine pulses with amplitude rising with engine speed (may be a few hundred millivolts at idle to several volts at higher rpm).
  • Fault states: open circuit → no pulses; short to ground → ~0V; short to battery → stuck high (constant voltage).
  • Signal frequency and pulse timing depend on engine design (cam turns at half crank speed); use factory waveform/specs for exact timing and amplitude).

Diagnostic algorithm

  1. Verify code and gather context: record freeze frame and check for additional codes (P0340, P0341, P0335, P0016, P0366).
  2. Identify sensor B and Bank 1 per vehicle service manual to avoid testing the wrong sensor.
  3. Perform a visual inspection of the sensor, harness, and connector for damage, oil, or corrosion; repair any obvious issues.
  4. With connector disconnected, measure reference voltage and ground at the PCM side or backprobe at the sensor connector: expect a stable reference (usually 5V) and a good ground. If missing, suspect PCM or harness upstream.
  5. Backprobe the signal wire while cranking/running: use a multimeter (frequency/voltage) or preferably an oscilloscope to observe waveform. Compare to known-good waveform or factory sample.
  6. For VR sensors measure AC output resistance and check with scope; for Hall sensors check supply, ground, and digital switching. Wiggle the harness during testing to reproduce intermittent faults.

Likely causes

  • Open or short in harness to camshaft position sensor B
  • Faulty camshaft position sensor B
  • Bad connector contacts or corrosion at sensor
  • Loss of reference 5V or ground from PCM

Fault status

⚠️ Status
Camshaft Position Sensor B (Bank 1) circuit fault detected — signal missing, out of range, or shorted/open.

⏱️ Diagnostic time: 1.0–3.0 hours
