The engine is running perfectly, I hate to tear into it right away but I can if need be. my problem was isolated to the bank 1 sensor. 08 gears, and 295/55 MT tire, running 91 octane. This worked for about two weeks and then I had code P0332 and for the 1 wire sensors The following is a recommended starting point for two common GM Resonant 1-wire sensors: AC Delco PN 213-3521, GM PN 12589867 – Commonly used on 1998-2006 GM LSx engines. We constantly run into tuning issues with 97-98 The knock sensor sends a signal to the ECU after detecting the high-frequency engine vibrations that are indicative of knocking. i thought the same thing. 5mm/3. LSx, LS1, LS2 LS7 GM Performance & Technical Information The only solution I seem to be left with is to buy LS1 just to turn off this stupid sensor. Now get codes P0327 and P0322 knock sensors low frequency/voltage When I measure the resistance of the sensors to earth I get 100. So this basically proves that my KR is false correct? Heres a thought about using the ls-2 knock sensors in the valley, just drill out the sleeve of the sensor a bit and use a different bolt. the knock sensor just "listens" to a frequency range. Knock Sensor Logging. The LS1 KS's are a single wire broadband sensor that the PCM sends a certain amount of voltage to, as the sensor detects knock, it changes the voltage reading and the PCM then knows how much knock is present by Does anyone know a good procedure to temporarily bypass both knock sensors on a 2000 LS1? I searched around and got some LT1 specific info, then found something for the LS1 which involved cutting the two knock sensor leads from the PCM (#11 & #51), then wiring in a pair of 100K ohm resistors, one lead to PCM and one lead to ground. 0L 8.
