Hello I will help,

Do you have the numeric code?

Ask Your Own Pontiac Question
Customer reply replied 7 months ago
No they didn't give me the numeric code just said crank sensor A
Pontiac Mechanic: George H., ASE Certified Technician replied 7 months ago

Different scantools describe a code in different ways and the exact code is necessary to get to the correct sensor. If the code is a P1336 then the computer must be taught the sensor value, you don't replace a sensor. There are actually three sensors. I suspect if a sensor needed to be replaced then it would be the 24x sensor but after replacement the computer still has to be taught the sensor value using a scantool with bi-directional controls. If you get the code number I can help you further with what to do.

Did they try to sell you a part? if they did what is the part number?

He wrote it down it's either c5523 or cs523 or css23
Pontiac Mechanic: George H., ASE Certified Technician replied 7 months ago

The sensor they listed CSS23 is the 24x sensor so to replace it the computer will need to be relearned.
