Camshaft Position Sensor Circuit Open
The P2614 code indicates an open circuit in the camshaft position sensor signal output circuit. This means the engine control module (ECM) detects no voltage or a broken connection in the wiring between the sensor and the ECM. The camshaft position sensor is critical for engine timing, fuel injection, and ignition timing. An open circuit prevents the ECM from receiving the camshaft position signal, often causing the engine to run poorly or not start.
01. Most Common Causes
- Open or broken wire in the camshaft position sensor circuit
- Corroded or damaged connector at the sensor or ECM
- Failed camshaft position sensor
- Blown fuse or faulty relay in the sensor power circuit
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Engine cranks but does not start
- Rough idle or engine misfire
- Reduced engine power or stalling
03. Step-by-Step Diagnosis
Step 1: Use a scan tool to confirm P2614 and check for other codes.
Step 2: Visually inspect the camshaft position sensor wiring and connector for damage, corrosion, or loose connections.
Step 3: Test the sensor's power and ground circuits with a multimeter (should have 5V reference and ground).
Step 4: Check the signal wire for continuity between the sensor and ECM; repair if open.
Step 5: If wiring is intact, replace the camshaft position sensor.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
No, it is not safe. The engine may stall or fail to start, and driving could cause further damage to the catalytic converter or other components.
How much does it cost to fix?▼
Typically $50-$150 for parts and labor, depending on the vehicle and shop rates. The sensor itself is often $20-$60.
