What happens when the crankshaft position sensor goes?
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.
Where is the crank crankshaft position sensor located?
The location of the crankshaft position sensor can vary from one vehicle to another. Obviously it must be close to the crankshaft, so it is most often located on the front underside of the engine. It can usually be found mounted to the timing cover. Sometimes it may be mounted at the rear or the side of the engine.

How do you reset a crank sensor without a scanner?
- Turn off all of the accessories.
- Accelerate the vehicle to 55 mph at part throttle.
- Cruise at 55 mph for another 5-6 minutes.
- Decelerate to 45 mph without using the brakes, and maintain 45 mph for 1 minute.
- Perform 4 deceleration cycles, without using the brakes, of 25 seconds each where no specific speed is necessary.
How long does it take to replace a crankshaft sensor?
