Wells SU7825 Engine Crankshaft Position Sensor;

Wells Vehicle Electronics Crankshaft Sensors are designed and manufactured to meet or exceed Original Equipment Manufacturer's specifications. The crankshaft position sensor identifies the position of the crankshaft to the ignition control module (ICM), engine control module (ECM) or powertrain control module (PCM). The sensor creates an electrical signal from the rotation of the engine. That signal is sent from the crankshaft sensor to the vehicle's computer. The computer then uses the information to control ignition timing, fuel injector timing and Variable Valve timing adjustments. When the crankshaft position sensor is not replaced, vehicles could experience no or hard start, long crank time, misfire, lack of power, excessive hydrocarbons in oil, spark plug fouling, catalytic converter failure, poor fuel economy, CEL/MIL illumination or intermittent shutdown.
