Genuine GM
GM genuine. Best sensors for the job

Looks good any way . Hopefully works
Should work , hopefully for a long time . Not put on had to wait on other parts. Parts I already should’ve ordered so I’d be ready for this special occasion to start taking truck apart . But …… getting it done eventually

Happy I paid for genuine GM
An expensive item for what it appears to be, but for the great deal of time and tediousness in replacing knock sensors I would not do it any other way. I considered relying on the old knock sensor wiring harness, but was so glad I got the new harness in addition to the sensors, as one of the old sensor nipples broke off in the old harness upon removal and I would have kicked myself thinking to try to save the money for what turned out to me to be a full-weekend job in replacing sensors. Wiring harness is a quality product and vehicle runs so much better on hills and under load with the new sensors and wires. ... show more

Good Knockers
Wanted to wait to comment till I had put the sensors to work for a while. Now, have put about 10K miles on the truck since replacement and have had no issues, no codes. They fit as well as the originals. Mine weren't malfunctioning; however, I was replacing the intake manifold gasket and didn't want to come back later and replace these. Torqued the sensors to 15 ft. lbs. For sensors and other electronic parts, I always use AC Delco. Never any issues. I was a little nervous about shipping these sensors put they did an adequate job keeping them safe while shipping. ... show more

Its been a couple weeks and so far so good. Factory sensor went bad at 110 k miles
Its been a couple weeks and so far so good. Factory sensor went bad at 110 k miles. Obviously if the check engine light were to come back on, my review would be much different. Time will tell

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

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
