Camshaft Position Sensor Circuit Intermittent (Bank 1)
Code P0369 indicates an intermittent signal from the camshaft position sensor on bank 1. This sensor monitors camshaft speed and position relative to the crankshaft, crucial for engine timing and fuel injection. An intermittent circuit issue can cause erratic engine behavior, stalling, or no-start conditions. Common causes include a faulty sensor, damaged wiring, poor electrical connections, or issues with the sensor's reluctor ring.
1. Most Common Causes
- Faulty camshaft position sensor
- Damaged or corroded wiring/connectors
- Intermittent electrical connection
- Damaged reluctor ring or timing chain issues
2. Symptoms You Will Notice
- Check Engine Light on
- Engine misfire or rough idle
- Hard starting or stalling
- Reduced fuel economy and performance
3. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect sensor wiring and connector for damage or corrosion.
Step 3: Test sensor resistance and voltage with a multimeter per manufacturer specs.
Step 4: Check for intermittent signal by wiggling harness while monitoring scan tool data.
Step 5: Inspect reluctor ring and timing components if sensor and wiring are okay.
