Review on Dorman Knock Sensor and Harness Kit (926-084) for Compatible Models by David Estevez

This product can be very profitable. While I had previously successfully completed this installation, this time one of these sensors kept failing, even after the wonderful support staff issued a replacement. I spent 3 hours removing the 5.3 intake manifold and cleaning everything thoroughly, thoroughly cleaning the threads in the valley cap indentations where the sensors are located. After about an hour of driving, I invariably get a horrible check engine light that indicates common low voltage codes P0332 and P0327. The time spent is the real price and it's annoying that the problem persists. I hate to assume that the Delco sensor is the answer just because it's "delco". Considering I have the same sensors in another car, no problem. Either way, great value if it fixes your error codes.
