P2614Camshaft Position Signal Output Circuit/Open

Q: What does code P2614 mean?

Camshaft Position Signal Output Circuit/Open. P2614 indicates that the powertrain control module (PCM) has detected an open circuit or abnormal voltage on the camshaft position signal output circuit, which is used to report camshaft position to other modules or systems. The PCM monitors this output circuit and sets the code when the signal line is open, shorted, or not responding as expected.

Symptoms you may notice

Illumination of the check engine light, often with no other noticeable symptoms
Rough idle or engine misfire due to inaccurate camshaft position reporting
Reduced engine performance or power, especially during acceleration
Intermittent stalling or difficulty starting
Poor fuel economy or increased emissions
Other driver-assist or powertrain systems may be disabled if the camshaft signal is shared

Common causes, most likely first

Open or damaged wire in the camshaft position signal output circuit
Corroded or loose electrical connector at the camshaft sensor or PCM
Failed camshaft position sensor
Faulty powertrain control module (PCM) output driver
Short to ground or short to voltage on the signal output wire
Aftermarket accessories or poor previous repairs tapping into the circuit

How to diagnose and fix it

Inspect the camshaft position sensor connector and wiring for obvious damage, corrosion, or looseness
Check for continuity and resistance on the signal output circuit between the sensor and PCM, looking for opens or shorts
Verify the sensor receives proper power and ground, and test the sensor output signal with a multimeter or oscilloscope
Check for technical service bulletins (TSBs) or known issues for the specific vehicle make and model
Replace the camshaft position sensor if testing indicates it is faulty
Repair or replace damaged wiring or connectors in the signal output circuit
If all else checks out, diagnose or replace the PCM as a last resort

Camshaft Signal Output Circuit Pitfalls

P2614 is often misdiagnosed as a simple camshaft sensor failure, but the code specifically refers to the output circuit, which may be a separate wire from the sensor to other modules, so testing the entire path is essential.
Some vehicles use the camshaft position output signal for variable valve timing or cylinder deactivation, so an open circuit can cause drivability issues beyond a simple check engine light.
A faulty PCM driver is rare but possible; technicians sometimes overlook it after replacing the sensor and wiring, leading to repeat repairs.
Aftermarket electrical accessories or remote starters improperly tapped into the camshaft signal wire can introduce opens or interference that set this code.
The code can be intermittent, so wiggle-testing the harness while monitoring live data or a scope is crucial to catch a marginal connection.

Can I keep driving with P2614?

You can usually drive with P2614, but if the engine runs rough, stalls, or loses power, avoid sustained high-speed driving or heavy loads and have it diagnosed promptly to prevent further damage or safety risk.
