Moderatesensor
Overview
The P0369 diagnostic trouble code means the PCM has identified a camshaft position sensor "b" circuit intermittent (bank 1) problem. This code indicates that a sensor or its circuit is not providing expected readings to the engine management system. Faulty sensor data can cause the PCM to make incorrect adjustments, affecting engine performance.
Symptoms
- Poor fuel economy
- Hard starting in certain conditions
- Erratic engine behavior
- Check Engine Light (MIL) illuminated
Common Causes
- Faulty sensor (out of range or failed)
- Corroded or damaged sensor connector
- Wiring issues (open, short, or high resistance)
- Physical damage to sensor
Diagnosis Steps
- 1Connect an OBD-II scanner and read all stored trouble codes and freeze frame data
- 2Locate the specific sensor referenced by the code
- 3Inspect the sensor connector for corrosion, damage, or loose pins
- 4Test the sensor output using a multimeter or scan tool live data
- 5Check the wiring between the sensor and the PCM for opens or shorts
