The crankshaft position sensor is an engine management component found on virtually all modern vehicles with internal combustion engines. 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 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.
Problems with the crankshaft position sensor can be linked to several issues. Overheating Engine. The excessive build-up of heat in the engine can lead to crankshaft sensor damage by melting the plastic covering. Circuitry Problems. 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. Driving with a failing crankshaft position sensor can be difficult and potentially dangerous.
It could lead to long-term vehicle damage and expensive repairs, or even stop the car from working at all. 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.
The most common symptom associated with a bad or failing crankshaft position sensor is difficulty starting the vehicle. The crankshaft position sensor monitors the position and speed of the crankshaft and other parameters that play an important role when starting the engine. If the crankshaft position sensor is having a problem, the vehicle may have intermittent starting issues or not start at all.
Another symptom commonly associated with a problematic crankshaft position sensor is intermittent stalling. 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. This is usually a sign of a wiring problem. However, a bad crankshaft position sensor can also produce this symptom.
Another issue of a potential problem with the crankshaft position sensor is an illuminated Check Engine Light.
A Check Engine Light can also be set off by a wide variety of other issues. Having the computer scanned for trouble codes is highly recommended. Slow or uneven acceleration can result from a lack of accuracy and make it difficult to maintain a constant speed. 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. A failing crankshaft position sensor cannot provide the right information about piston positioning in the engine, causing a cylinder to misfire.
This could also occur from faulty spark plug timing, but if the spark plug checks out, then the crankshaft sensor is likely the source.Engine Crankshaft Position Sensor.

Many newer cars have computerized engine management systems that rely on sensors to report data to the computer. The crankshaft position sensor is used in conjunction with the camshaft position sensor to control ignition timing and to let the computer know when to inject fuel and provide spark sequence.
Due to the mounting locations of this sensor, it is common for heat and oil leaks to cause this sensor to fail. The crankshaft position sensor will usually let you know when it needs replacing. The Check Engine warning light will illuminate and you may notice that your vehicle has a hard time starting or running smoothly. When you notice any of these signs, schedule an inspection.
The sensor provides the management system with the information it needs to control ignition timing, and it lets the computer know when it needs to provide sparks and fuel. Get an upfront price.
