New Member Looking For Advice

    Hello, I recently bought a 2001 Sierra Z71 with some problems and I'm looking for some advice. When I bought the truck, the “SERVICE ENGINE SOON” light was on. When I hooked it up to the diagnostics machine, the error was “P0332 – Rear Bank Knock Sensor” so I decided to purchase 2 new knock sensors from a seller on ebay. When I pulled the intake, I discovered that the old rear bank knock sensor was very corroded and wet. Anyway, I replaced both sensors, hooked the original wiring harness back up to them and put everything back together. After reconnecting the battery, I started the truck and the light was gone. However, after driving the truck for about 10 miles, it came back on so I again hooked the diagnostics machine back up. This time, I got errors for both sensors (P0327 & P0332). I’m wondering if I have a defective wiring connector or if it’s just a problem with the cheap sensors I purchased from ebay. Anyway, I’m really hoping to avoid taking everything apart and would appreciate any advice or suggestions you all may have.

    Welcome to the site! Sounds like it might be in the wireing harness to the sensors. Can you see a reason why the original one was wet?
