Camshaft Position Sensor B Circuit Intermittent Bank 1
What it means
P0369 means the camshaft position sensor "B" signal on bank 1 is intermittent. The ECM relies on cam position to sequence fuel and spark, so a dropping signal can cause stalling, hard starting, or an occasional no-start, along with rough running. The fault comes and goes, but it should be treated as a genuine starting and driveability risk.
Can I keep driving? Risky — an intermittent cam signal can cause stalling, hard starting, or an occasional no-start, so treat it as unreliable and repair it before relying on the car.

How to diagnose & fix
Work through it in order
- Read freeze-frame data and note when the signal drops.
- Wiggle-test the sensor B connector and harness.
- Inspect the sensor, its air gap, and the reluctor ring.
- Replace cam sensor B if the signal is erratic.
- Verify timing components if the signal correlates poorly with the crank. Clear and re-test.
