#2001 dodge neon drive shaft sensor location professional#For this reason, if you suspect your crankshaft position sensor has an issue, have the vehicle inspected by a professional technician right away. Issues with the crankshaft sensor can quickly lead to problems that affect the drivability of the vehicle. The crankshaft position sensor is critical to proper engine functionality and performance due to the vital signal it provides for engine calculations. Have a mechanic inspect the sensor - as insufficient fuel economy can occur from other issues as well. The engine will use more gas than it needs on short and long drives, reducing overall fuel economy. Lacking accurate timing information from the crankshaft position sensor, fuel injectors won't pump gas into the engine efficiently. Any out-of-the-ordinary vibrations should be inspected by a mechanic as soon as possible. The shaking can also interfere with the engine’s tracking of mileage. When this happens, it means the sensor is not monitoring the crankshaft’s position, leading to vibrations that affect overall engine power. While idling at a red light or otherwise stopped, you may notice the engine grinding or vibrating. Rough Idle and/or Vibrating EngineĪnother sign of a crankshaft position sensor problem is rough idling. This could also occur from faulty spark plug timing, but if the spark plug checks out, then the crankshaft sensor is likely the source. A failing crankshaft position sensor cannot provide the right information about piston positioning in the engine, causing a cylinder to misfire. Should you feel or hear a brief stutter in the engine, it may be a sign of misfiring cylinders from a bad crankshaft position sensor. Slow or uneven acceleration can result from a lack of accuracy and make it difficult to maintain a constant speed. With inaccurate input coming from the crankshaft position sensor, the engine control unit can’t make the adjustments to spark timing and fuel injection as the engine speed increases. Having the computer scanned for trouble codes is highly recommended. A Check Engine Light can also be set off by a wide variety of other issues. #2001 dodge neon drive shaft sensor location driver#If the computer detects a problem with the crankshaft position sensor’s signal, it will activate the Check Engine Light to alert the driver of the problem. Check Engine Light Comes OnĪnother issue of a potential problem with the crankshaft position sensor is an illuminated Check Engine Light. However, a bad crankshaft position sensor can also produce this symptom. This is usually a sign of a wiring problem. 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. The crankshaft position sensor is an engine management component found on virtually all modern vehicles with internal combustion engines.
