P1705, P0325,P0120. Any ideas where to start?

Question

I have k&n cold air intake, deep water caused it to stall. It immediately started it up and has been running low on power. Made it home a few codes came up. P1705, P0325,P0120. No never replaced the knock sensor yet either. Any ideas where to start?

Answer 1

I would start with the TPS. The code P1705 and P0120 are both TPS codes. The 325 code won't even cause the light to come on. It is quite possible the water got on the TPS or the connector for the TPS and shorted it out. I would start with that.
