Bad Crankshaft Position Sensor Symptoms
If you suspect that your crankshaft position sensor is failing, there are a few symptoms that you can look out for. Here are some of the most common signs of a bad crankshaft position sensor:
1. Issues Starting The Vehicle
The most common symptom associated with a damaged or malfunctioning 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 in starting the engine. If there is a problem with the crankshaft position sensor, the vehicle may have intermittent starting problems or not start at all.
2. Intermittent Stalling
Another symptom of a bad crankshaft position sensor is intermittent stalling. If the sensor is not functioning properly, it can cause the engine to stall without warning. This can be extremely dangerous and should be addressed as soon as possible.
3. Check Engine Light Comes On
Another possible problem with the crankshaft position sensor is the check engine light coming on. When the computer detects a problem with the crankshaft position sensor signal, it activates Check Engine Light to alert the driver to the problem. The check engine light can also be triggered by various other problems. An error code scan of your computer is strongly recommended.
4. Uneven Acceleration
If the crankshaft position sensor is not functioning properly, it can cause uneven acceleration. The engine may feel like it is hesitating or stuttering when you try to accelerate. This can be extremely dangerous and should be addressed as soon as possible.
5. Engine Misfires Or Vibrates Roughly At Idle
Another common symptom of a bad crankshaft position sensor is engine misfires or a rough idle. If the sensor is not functioning properly, it can cause the spark plugs to fire erratically or not at all. This can lead to a loss of power and decreased fuel efficiency. It can also cause the engine to vibrate or shake.
6. Rough Idle And/Or Vibrating Engine
If the crankshaft position sensor is not functioning properly, it can cause the engine to vibrate or shake. This can be extremely dangerous and should be addressed as soon as possible.
7. Reduced Gas Mileage
Without accurate timing information from the crankshaft position sensor, the fuel injectors cannot effectively pump gas into the engine. The engine uses more fuel than needed for short and long trips, reducing overall fuel consumption. Have a mechanic check the sensors – as poor fuel economy can also be caused by other issues.
Crankshaft Position Sensor Replacement Cost
If your crankshaft position sensor needs to be replaced, the average cost for a mechanic is between $120 and $200. The parts cost for the sensor itself will be between $30 and $60. The labor cost will be between $90 and $140.
