I bought the full kit not knowing what I'd find when I got the intake manifold off. I only replaced one bad sensor. The fault was 'typical' and caused by corrosion due to standing water around the rear sensor. Installed a new sensor from this kit and it is good to go.4 Month Update: This sensor provided less than 1% of the original's service life. Resistance test is still good, so wiring and ground are fine. But the sensor now has no voltage output on the oscilloscope in response to engine running or simulated knocks. That confirms the sensor has an internal fault. I contacted seller with no response so far. Given the time and cost for installation, I wish I had gone with OEM.

These worked perfect for my problem. I had a check engine light because of bank 2. After careful installation, and sealing everything, my check engine light went away and has yet to come back and it's been 3 months. For the money, these are top notch sensors.

Per the GM bulletin, you will need to use RTV sealant to seal up these sensors. The rubber seals harden over time allowing moisture to gather in the sensor area and corroding the sensors. As suggested by some of the reviews, you may need to adjust the wiring a little bit so that the wires reach both sensors appropriately, honestly not a big deal.When removing the EGR pipe from the intake, it's a good idea to remove the pipe assembly. Even though it's a "flexible" pipe, the pipe may break due to age. This will cause a major vacuum leak if the pipe breaks between the EGR and the intake manifold.In my case, I ended up having to replace the EGR pipe assembly which also lead to replacing the exhaust manifold due to old age of the parts. Just be aware, my truck has 270k miles on the odometer and I ended up replacing both parts. It also lead to extracting some broken exhaust manifold bolts as well. I wish I knew these things before I tackled this project and had ordered the parts before hand.So far, no more knock sensor codes!

No issues on my 2006 Cadillac Escalade running these as of thus far. Been installed since October 2023. It's now June 24. So the last it almost a year. Good price point. And as long as they last another couple years, I'll be happy as can be.

As many have said, just doesn't seem to work. I had low voltage on one original OEM sensor in a 2004 Chevrolet Silverado 2500HD 6.0L with 88k miles. I put these in and now get codes for low voltage on both sensors after about 40 miles. Could be the wrong voltage spec, could be cheap junk, could be they were damaged in shipping. I did all the ohming, cleaning, grounding, torquing, and siliconing you are supposed to do on these engines. I found a pair of acdelcos for $50 on ebay and got a dorman wiring harness from AMZ. These are going back to AMZ once I get back under the intake manifold. Too bad.

Had one knock sensor go bad -Rather than pull intake I screwed one of these into block at rear of right side above exhaust manifold and wired to connector.Simple tests with voltmeter ( ac) and knocking with screwdriver handle give about same readings.
