Where is the IAT sensor located
I have a 2007 Silverado; I have been plagued with OBDII code P0332 Knock Sensor (Bank 2 Sensor 2) for a couple of years. I got the parts from Rock Auto.com and replaced both sensors and the senor wiring harness. After six months of driving the P0332 came back; I have taken it to a dealer shop twice and they can’t isolate the problem. So I took it to an independent repair shop, they replaced the bank 2 sensor and the P0332 code went away, after about 40 miles of driving, the ENG light came back on and now I’m getting a code P0327 (Bank 1, Sensor 1). I took it back to the shop and they replaced the bank 1 sensor. The next day the ENG light came back on and I’m still getting code P0327 (Bank 1, Sensor 1). Each time I take it back to the shop they want to charge me for repairs. I have invested over 1200 bucks trying to fix this issue, does anyone have any ideals, this dam truck is breaking my bank.
Also, This whole thing started when I steamed cleaned my engine; when I initially did the repairs I put a bead of High Temp RTV round the top edge of the rubber boot on the wiring leads to keep water out, could this have effected the function of the Knock Sensors?
