    • Genuine Replacement Part That Works
This is a genuine GM part. I had a knock sensor fail (known issue) on my 2002 Chevrolet Suburban. While everything was apart, I replaced the wiring harness as well. The wiring harnesses sit in an area of high heat and by this time are almost 20 years old. As expected, the clips on the old harness broke when I removed them from the knock sensor. I was very glad to have a ready replacement. The wiring harness sits below the intake manifold which means you have to remove the intake manifold to get to it. This is not something that you want to do more than once, so replacing everything that you need to while it's apart makes sense. I much prefer the genuine GM part to the Dorman alternative. I figure the GM part lasted 20 years the first time, it'll last the remainder of the vehicle's life. While everything was accessible I also replace the oil pressure sending unit and the valley pan gasket (which was leaking). There are a lot of videos and chats out there about making this repair. It is of medium difficulty for a DIYer. It took me 8 hours to do the repair (including replacing the valve cover gaskets and all the engine and intake clean up - the top end of the engine looks new). You will need a new intake gasket as well to ensure a good seal as well as the torque specifications for the intake manifold. ... show more

    • It seemed genuine
It is just a wiring harness but too seemed to not be knock off like most stuff on here. Worked good. Good quality as OE goes.

    • This is the wire you need to fix your Knock Sensor Error codes
I've had success with the doorman version of this wire once, but then it didn't work. I bought another doorman, and more sensors, no dice. After getting the genuine wiring harness, I think I have fixed the issue. The primary thing I've noticed is that the contact wire that goes into the sensor is thicker and also doesn't seem to move. This is the main reason I think you can get the knock sensor codes to hit. If its not making good contact to the sensors from the harness, you will throw the code even if the sensors are good. I've used delphi and ac delco sensors and the doorman harness still gives you the error codes, but this harness will not. Its also more insulated. This is the redesigned version of the harness so you might not even need the RTV sealant around it (but it certainly won't hurt). As long as your sensors measure in the correct range, and you use THIS harness, I think that should solve your problems. My application was a 2003 Corvette with the LS1 base engine. ... show more
