Any ideas why a crankshaft position sensor would need to be relearned on close to a monthly basis. Car runs great until I get the 0300,0302, 0303, and 0339 codes. Then the car goes into limp home mode and will only get to about 25 mph before it starts shaking. This last time I replaced the sensor and then had it relearned. Waiting to see if the problem comes back. Thanks in advance.

 

Maybe wiring.

 

Question: Does your car fall into Limp Mode when you try to start it like long cranking, start and a engine light coming on?
