Review on 🚗 High-Quality Dual Knock Sensors with Wiring Harness Kit for GM Vehicles - Replace # 12601822 12589867 917-033 by Amrozi Goodall

Worst product I have ever bought from Revain for my cars. I bought them in August but didn't use them until last month due to health issues. After installation, my MIL never went off. So I went out and bought a new ECM for my truck, thinking it was a computer. After a long time of diagnosing and checking the entire wiring harness, I found that the knock sensors were faulty. I've been turning wrenches for almost 45 years (almost my entire adult life) and I've never had so many problems with the same problem. After replacing it with genuine AC Delco parts, my MIL went out and had no more problems. Do yourself a favor and buy genuine OEM parts, not cheap imitations. You lose more in the long run. I had to do this job twice which cost me twice as much if I decided to buy an OEM. Knock sensors are fragile, so careful handling is extremely important. Over-tightening will actually result in an incorrect sensor code, so I was very careful when tightening. I don't usually leave reviews for the products I buy, but this time I did it so other people wouldn't do the same thing I did. Do yourself a favor and shell out the extra money and buy the right part. In this company's defense, I can't say if they were bad outright or if they were mishandled during shipping. Anyway, they were bad from the start.
