Camshaft Position Sensor Signal Circuit Low
The P2615 code indicates that the Engine Control Module (ECM) has detected a low voltage condition in the camshaft position sensor signal circuit. This sensor monitors the position and speed of the camshaft to optimize fuel injection and ignition timing. A low signal can result from a faulty sensor, damaged wiring, poor electrical connections, or a short to ground. This condition can cause drivability issues and may prevent the engine from starting.
01. Most Common Causes
- Faulty camshaft position sensor
- Short to ground in signal circuit
- Damaged wiring or connector
- Corroded or loose electrical connections
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Engine hard to start or no start
- Rough idle or misfire
- Reduced engine power
03. Step-by-Step Diagnosis
Step 1: Use an OBD2 scanner to confirm code P2615 and check for additional codes.
Step 2: Visually inspect the camshaft position sensor wiring and connector for damage, corrosion, or loose pins.
Step 3: Test the sensor's voltage and ground supply with a multimeter; compare to manufacturer specifications.
Step 4: If supply is good, test the sensor's signal output while cranking the engine; replace sensor if signal is missing or weak.
