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. Intermittent StallingĪnother symptom commonly associated with a problematic crankshaft position sensor is intermittent stalling. If the crankshaft position sensor is having a problem, the vehicle may have intermittent starting issues or not start at all. The crankshaft position sensor monitors the position and speed of the crankshaft and other parameters that play an important role when starting the engine. The most common symptom associated with a bad or failing crankshaft position sensor is difficulty starting the vehicle. Usually, a problematic crankshaft position sensor will produce any of the following 7 symptoms that alert the driver of a potential problem that should be serviced. It could lead to long-term vehicle damage and expensive repairs, or even stop the car from working at all. Faulty voltage or loose, worn-out, or damaged wiring can disrupt the signals sent to and from the crankshaft sensor, causing it to have issues.ĭriving with a failing crankshaft position sensor can be difficult and potentially dangerous. The excessive build-up of heat in the engine can lead to crankshaft sensor damage by melting the plastic covering.Ĭircuitry Problems. Problems with the crankshaft position sensor can be linked to several issues. The crankshaft speed and position are some of the most important parameters used in engine management calculations, and many engines cannot run if the crankshaft position sensor is not providing an accurate signal. It monitors the position and rotational speed of the crankshaft and sends the information to the engine control unit so it can make appropriate adjustments based on operating conditions. For car applications, see LS Car Series Wire Kits, and for high-horsepower applications, see our new Black Widow wire sets.The crankshaft position sensor is an engine management component found on virtually all modern vehicles with internal combustion engines. This kit fits most LS-equipped trucks, SUVs, and Vans with coils in OEM mounting positions. This LS spark plug wire kit measures 10 in long tip-to-tip and is considered the "truck/van" set.
