Discuss the causes and fixes for P1372 Oldsmobile OBDII Code
-
I got a DCT code on my olds intrigue and I replaced the crankshaft position sensor behind the starter and now I'm getting the same code and a p1372 and the car cranks but doesn't start
-
Unfortunately, other than the Crankshaft Position Sensor, I have not seen any there is no other components setting the P1372 code. I also checked a national database of repairs for your model and year, and there is no more information either.
Do you have a 3.5L or 3.8L engine? The Crankshaft Position Sensor on the 3.8 is behind the crank pulley. -
It's a 3.5 I have to remove the starter to get to the sensor.
Is there 2 sensors? For there to be A and B correlation would that mean 2 sensors?What should I check next?
-
It means correlation with the Camshaft Position Sensor, which in theory should be your next step.
-
Is there a specific way I should install the sensor or not I just put it in and plugged it in am I missing something?
-
No, just remove the old sensor and installed the new one. I check around with some friends and they said that to make sure you use and AC Delco sensor, and if you us the AC Delco, then the Camshaft Position Sensor is more than likely the problem.
