2010 Jeep Compass Limited 4 Cyl 2.40L
Misfiring after crankshaft sensor replacement
I have a 2010 jeep compass and got a po300 code indicating a bad crankshaft sensor. Put a new sensor in. Drove it around about 20 minutes and it seemed like the sensor relearned and the car was driving fine. The past 2 days it started out missing and sputtering and I had to drive it around 20 minutes till it was fine again. What are possible reasons for this?
A P0300 is a general misfire code when two or more cylinders are misfiring not something that is normally caused by a bad crank sensor. Most likely your old crank sensor was just fine.
