    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.

    Thanks,
    Chris

    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?

    Welcome to the site and glad to hear you originally fixed the issue. Now as for the light I would listen to seffieldvillage on that one. That's where i would start anyway. Elctronics is where I am least knowledgeable though lol. Good luck with the fix though.

    Thanks for the tips, I think I am going to pull the intake again this weekend. I'm fairly certain that the seller on ebay sold me the wrong sensors because he had a wide range of vehicles listed for the sensors and after checking, I know that some of the vehicles he has listed take different sensors than others. Buyers beware, his ebay name is "global-automotive" and the link to the senors I bought is http://cgi.ebay.com/ebaymotors/ws/e...0141008140&viewitem=&sspagename=STRK:MEWNX:IT

    I am going to go to the local auto parts store to buy new sensors. I will check the resistance in the new sensors and compare with sensors I bought on ebay. I also will check the resistance in the wiring connector and may end up replacing the connector as well. I'll let you all know what I find out.
