P2614 indicates the Powertrain Control Module (PCM) detects an open circuit in the camshaft position sensor signal output circuit for Bank 1 (the engine bank containing cylinder #1). The PCM cannot receive the camshaft position signal it expects, which affects engine timing and fuel injection synchronization.
The internal circuitry of the CMP sensor has failed, creating an open circuit that prevents signal transmission to the PCM.
The signal wire between the CMP sensor and PCM is broken, cut, or has high resistance due to corrosion or damage.
The CMP sensor connector pins are corroded, bent, broken, or have poor terminal contact, preventing signal continuity.
The signal circuit has an open condition, often due to wiring insulation damage or connector issues.
The PCM's internal circuit responsible for processing the CMP sensor signal has failed - this is rare and typically diagnosed after other causes are ruled out.
Inadequate ground connection at the sensor or PCM can cause signal circuit issues, though this typically causes multiple codes.
It is not recommended to drive with this code. The engine may run poorly, misfire, or fail to start entirely. Continuing to drive may cause further damage or leave you stranded.
Almost never. The PCM is rarely the cause of P2614. This code is almost always caused by the camshaft position sensor itself or wiring/connector issues. Many technicians and shops incorrectly recommend PCM replacement as a first step, but this is usually unnecessary and expensive.
This is a common misdiagnosis. Some technicians may not thoroughly check the sensor and wiring before recommending the most expensive fix. Always verify the CMP sensor and its circuits are functioning correctly before considering PCM replacement.
In almost all cases, you can replace only the camshaft position sensor itself. The sensor is a standalone component that can be removed and replaced without replacing any engine components or the timing cover assembly.
