asked by on

My car has 95000 miles.
My car has a manual transmission.

A crankshaft position sensor is an electronic device used to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control the fuel injection or the ignition system timing and other engine parameters. When this is faulty or not working properly, this will cause problems with the ignition system and generating spark transmission to the spark plugs resulting in starting problems and other performance issues. I would recommend having an expert from YourMechanic come to your location to diagnose and replace your crankshaft position sensor.
