Q: Is it expensive to change my crank sensor?

asked by on

My car fails to start after running it for a while. Always have to wait for about 20mins before restarting.

My car has 120000 miles.
My car has an automatic transmission.

Hello. Most of the time when this occurs on this vehicle it is caused by a failing crankshaft position sensor. These will fail intermittently on this engine and cause these same symptoms. It can also be an issue with the fuel system or possibly another sensor, but this is the most common. I usually monitor the signal from this sensor when the issue is occurring to see if it is functional.
