Buddy has a 93 leg 2wd nonturbo. Runs great, up until normal operating temp, then bogs down and dies? Throws a knock sensor code. Checked the connection to the sensor, fine, connected/no corrosion. I was gonna grab a multimeter and test the signal to/from the sensor.

Any ideas?

MAF? When my car's was broken, it ran all right when cold - at first. As it got worse, it starting driving and bogging all to hell no matter what the temperature.

Usually if it throws a knock sensor code, its the knock sensor. Not all sensors can be tested with a multimeter. Ony thing you can check is to make sure its not shorted, but even that doesnt say anything really. Knock sesnor makes a very small ac signal for the ecu. Just replace it and it should fix it.

 

nipper

Well he's had a weapon r intake for like 2 years, throwing the MAF code the whole time. So i told him to clean it or get a new one, got a new one and to no avail, but he's been driving it all over with the MAF code this whole time. Also, the parts guy told me the cam position switch and the knock sensor are the same thing? I was baffeled..

lol so neway, is the knock sensor straight on the top to the passengers side of the Crank position switch? Thats what i thought it was just lookin in there, but wasn't sure

No the knock sensor is not the same thing. Smack that guy please. The knock sensor located at the back and on the drivers side of the motor. Look down between the intake manifold and throttle body. You should see something that looks like this beside the coolant passage.

 

The thing you are looking at is the oil pressure switch that turns on the oil light on the dash.

Sweet thanks buddy, well obviously i was checking the wrong connection so hopefully the damn things unplugged (wishfull thinking)

I hope that its unplugged as well. But it probably won't be the case. These things are kinda pricey for a new one. But you could try posting a wanted thread in the classifieds to see if a member has a good extra one.

rockauto.com has one for like 40 bucks. reasonable?

checker was like 299! AH! good god lol

Yeah, thats a good price for one. My mom's is bad on her 98, and she has been putting it off because the parts stores tell her its dealer only.

Dealer only and by the way its the same thing as the cam position switch... SMACK!!!!!!!!!!!!

They've got her's for 46 and some change shipped to my door. Looks like she's not going to have to stare at the ces for much longer, lol.

Well. There's actually the knock sensor, the cam sensor, and the crank position sensor. They're three different sensors.
