Ok, I have to bother you guys (and gals) again. I have a 1997 Seville STS and I get a knock sensor low voltage error from the OBDII and I have sense then purchased a new knock sensor. I also bought a Chilton and a Haynes book to find out where the knock sensor goes, but I havent had any luck finding it. I can find just about anything else in the dang car but that. If someone could direct me in the right direction I would be enthralled. Thanks again.
Thanks, any information helps. I just gotta take a day and make myself find the sensor, its in there somewhere. I took the Haynes book back to where I got it, but Im stuck with this POS Chilton manual. They used to be so helpful 20 years ago, what the heck happened? Thank again.
loosen the 4 nuts to the plem. cover. Take the 4 studs out as well as the 6 bolts or so holding plem over the valley. Be carefull not to dropanything down into the exposed intake runner when you lift the plen. to get inside the intake valley. Lirt the plen. you will see the starter and a sensor. That roundish sensor with one wire going to it is the knock sensor.
Thanks again for all your help people. I got a wild hare up my butt and finally got that sensor installed. The computer hasnt given me the error yet. It looks to be fixed. I also cleaned out the runners a little, but they were pretty clean for having 176,000 miles on it. I didnt have to do much. Thanks again.
remove plastic engine cover, (13mm socket) remove fuel rail, (10mm) and remove PLASTIC intake manifold (10mm)...Take your time be careful. Knock sensor is the small white and blue harness on top of engine block(in the middle). Your starter is on your right for future references. You might as well replace intake manifold gaskets and clean all the gunk out of your PLASTIC intake manifold while your at it.
