I was recently driving my 05 silverado and hit a fair size pot hole..After I hit the pot hole I noticed my check engine light came on. I went to auto zone and got the code no. PO332 and PO 315. From what info I gathered this is some type of sensor. Is this something that can be fixed by un-pluging the sensor and pluging back. I was really trying to avoid a visit to the dealership. Thanks for any help with this issue.

 

So, did they try to sell you a knock sensor? As for P0315, I don't see how the PCM can suddenly lose the crankshaft position variation learn factors. I think you'd be well advised to take it in for service, a reputable repair shop would do.

I agree with EinST, I also would suggest you take the vehicle in for service. A certified technician should be able to offer a more accurate resolution with a physical inspection.

Please keep us posted.
