The CMP sensor is crucial for the engine's timing. An incorrect installation could lead to:
* Misfires: The engine may run poorly, misfire severely, or even stall. This reduces power and control, making the vehicle unsafe to operate, especially at highway speeds.
* Engine damage: Incorrect timing can cause catastrophic engine damage, such as bent valves or a broken piston. This can result in a complete engine failure, leaving you stranded and potentially causing an accident.
* Check Engine Light (CEL): The CEL will almost certainly illuminate, indicating a problem. Ignoring this light is dangerous.
In short: If the CMP sensor is improperly installed, do not drive the vehicle. Have a qualified mechanic diagnose and correct the problem before driving it again. Driving with a faulty CMP sensor is risky and could lead to expensive repairs or a dangerous situation.
