Seriously now, has anyone every replaced the knock (detonation) sensor before and actually knew that IT was the problem? What causes these things to fail in the first place?
I keep getting a code 43 on my engine (Knock sensor). Now, I think I know WHY I'm getting a message from mister knock sensor, but its just a theory.
Oh, btw, the car is a 1988 Olds Touring Sedan( 98 Regency). With the
3800 engine VIN 'C'.Now onto my theory of why I'm getting a trouble code:
Since I've owned the car its always had an overcooling problem which I just rectified by replacing the el-cheapo aftermarket t-stat with a GM one. Fine done, plety-o-heat this winter! Nice... Now, I've read in my service manual that the computer will not operate in 'Closed Loop' mode until certain engine operating conditions are met ie. proper operating temp!
Therefore, since the enigne has never (since I've had the car) been in closed loop mode then all the data from this sensor was just ignored!
But now that its getting into the loop its seeing either a legit problem OR the sensor is bad. I'm hedging my bets on a bad sensor, after all its an original part.
Sorry about the lengthy post, just wanted to include as much detail as possible. Any insight into this would be most appretiated. Opinons welcome.
Please post to group!
Thanks,
