Replaced the Crankshaft Position sensor - Answered by a verified Dodge Mechanic. I bought a 2001 BMW 525i with 94k miles on it. The crankshaft position sensor is installed on the transmission housing where the transmission attaches to the engine block. If the crankshaft position sensor or its wiring have any issues, it can cause the crankshaft signal to be cut off while the engine is running, which can cause the engine to stall. Keep in mind that this code may also come up because of a bad timing belt or chain. Second, CKP functions as a position sensor, which the ECU uses to calculate the position of cylinder #1 at top-dead-center (TDC). To synchronize the fuel injector and coil firing sequence, the camshaft position sensor is employed to detect which cylinder is firing. All these symptoms may appear individually or together. 1) Irregular Stalling. What are the symptoms related to a bad crankshaft position sensor? When something occurs to interrupt the transference of signals, you will likely end up receiving an error code. Symptoms of a Bad Crankshaft Position Sensor. A CKP sensor, as its name implies, monitors the crankshaft's exact position during the combustion cycle and makes sure that the engine is rotating at a constant speed. Depending on the vehicle, the PCM uses this crankshaft position information to time the spark properly or on some systems it is only for misfire detection and does not control . The computer receives a malfunction code when the sensor is completely gone. This stands for 'Crankshaft Position "A" Circuit Malfunction." The PCM throws the error when it can't detect a signal from the crankshaft position sensor. Your engine's cylinder head houses one or two camshaftsa shaft equipped with offset lobesto operate the intake and exhaust valves.
