P0369: Camshaft Position Sensor B Circuit Intermittent (Bank 1)

Quick answer: The ECU sees the Bank 1 camshaft position sensor B signal dropping in and out intermittently.

Drivers also search this fault as intermittent bank 1 cam sensor B code, bank 1 exhaust cam sensor intermittent, random bank 1 cam signal dropout.

Severity: high Family: powertrain Related paths: 15
Meaning

What P0369 usually means

P0369 means the Bank 1 sensor B signal is not gone all the time, but it becomes unstable often enough to trigger an intermittent fault. That pattern strongly fits heat-soak sensor failure, loose connectors, wiring movement, oil contamination, or exhaust-cam timing variation that only shows up under certain conditions.

Fast triage

Start here before chasing parts

  • Scan first: save freeze-frame and pending codes before clearing anything.
  • Confirm the complaint: compare the stored code with current drivability symptoms.
  • Use context: trims, live data, and related codes usually narrow the fault faster than guesswork.
  • Work simplest to hardest: leaks, connectors, maintenance items, and known patterns before expensive components.
Initial checks

What to check first

  • Ask whether the failure happens hot, on bumps, or only after restart because the timing matters.
  • Inspect the Bank 1 sensor B connector carefully because many intermittent faults are connection problems first.
  • If reduced power or correlation codes appear too, keep timing context in the diagnosis instead of blaming the sensor alone.
Driving risk

Can you keep driving?

P0369 can leave the vehicle with random long-crank, stalling, or no-start behavior, so it deserves prompt diagnosis.

High urgency: If symptoms are active, reduce driving and diagnose quickly before secondary damage builds.
Likely causes

Common causes behind this code

  • Bank 1 cam sensor B failing intermittently with heat or vibration
  • Loose, corroded, or oil-soaked connector
  • Harness damage that opens only under movement
  • Intermittent timing variation making the exhaust-cam signal unreliable
  • Poor voltage or ground integrity that comes and goes

Cause phrases often tied to this code: heat-related cam sensor, loose connector, oil in connector, intermittent wiring fault, timing fluctuation.

Diagnostic order

Suggested workflow

  1. Match the code to the complaint pattern and temperature timing.
  2. Inspect the connector and harness while looking for oil intrusion or movement-related faults.
  3. Check scan data for exhaust-cam sync dropout during the actual bad event if possible.
  4. Test the sensor hot if the problem mainly appears after heat soak.
  5. Recheck for companion timing or VVT codes after the electrical issue is addressed.
Avoid guesswork

Common mistakes

  • Clearing the code after one good restart and assuming the problem is gone.
  • Ignoring oil contamination inside the connector on an intermittent cam code.
  • Stopping at sensor replacement when the engine still has correlation clues.
Repair path

Practical fix guidance

  • Fix the intermittent path directly and confirm the signal stays stable through repeated hot and cold cycles.
  • If the code returns with correlation faults, continue into timing inspection rather than declaring victory early.

FAQ

Quick questions about P0369

Can P0369 be heat-related?

Yes. Many intermittent Bank 1 cam-sensor failures show up most clearly after the engine is hot.

How is P0369 different from P0365?

P0369 specifically points to signal dropout that comes and goes, while P0365 is the broader Bank 1 sensor B circuit umbrella.

Can P0369 be caused by wiring instead of the sensor?

Absolutely. Loose pins, oil-soaked connectors, and movement-sensitive harness faults are common causes.
