Error code P0369 indicates that the engine control module (ECM) has detected an intermittent signal from the camshaft position sensor B on bank 1. This sensor monitors the position of the camshaft to synchronize fuel injection and ignition timing. An intermittent fault can cause rough idling, poor acceleration, or even stalling. This guide will help you diagnose and fix the issue.

Frequently Asked Questions

Can I drive with code P0369?
It is not recommended to drive with P0369. The intermittent sensor signal can cause stalling, rough running, and potential engine damage. Have it diagnosed as soon as possible.
What causes an intermittent camshaft sensor signal?
Common causes include a faulty camshaft position sensor, damaged wiring or connectors, a loose timing chain/belt, or metal debris on the sensor. Electrical interference can also play a role.
How much does it cost to fix error P0369?
If DIY, a replacement sensor costs $30-$100. If a mechanic replaces it, expect $150-$250 including labor. Timing chain repairs can cost $500-$1500.
Will a bad camshaft sensor cause a no-start?
Yes, if the sensor completely fails, the ECM may not know camshaft position, preventing the engine from starting. Intermittent faults may cause hard starting or stalling.
Is P0369 the same as P0365?
No. P0365 indicates a circuit malfunction (open or short), while P0369 specifies an intermittent signal. Both involve camshaft position sensor B on bank 1.
