Knock Sensor Issue
 

OK....

I thought I'd start a new thread for this.

I'm getting error code 5 for the knock sensor. I have replaced the knock sensor with a new one, and I even went as far as to run a completely new wire to the ECU pin for the knock sensor and I'm still throwing a knock sensor code. I have OHM tested the connection all the way from the sensor to the PIN and it does have a connection, so at this point I'm not sure what more I can do to make this stupid thing turn off.

It is a brand new sensor, and a brand new wire. Connection is good, and I reset the ECU and it instantly turned back on. What could possibly be wrong to make it act this way with a new wire / sensor?

I get a knock sensor code also, I bought a new knock sensor, and when I went to replace the old one, the wire is not attached to anything. . . old one could be fine. Problem is. . . I have no idea where to attach this empty lead. Could you take a picture of where it goes???

From the factory I believe the wire goes behind the alternator into the rest of the harness.... if you can't locate the wire, you can always run a new one right to the ECU pin connector wire. I believe the knock sensor is white, download the FSM and look @ the wiring diagram. You can easily figure out which one it is.

I'm just having issues at this point with my connected sensor not working :( Not sure what else to try, but I just got some new advice via a PM so I'll try it out and let everyone know.

So you got rid of all the other codes?

Yep all codes are gone, and the knock sensor problem is now solved as well. NO CHECK ENGINE LIGHT!!!!!!!!!


I just have to get the car to idle better, as it is very spiradic right now, but other than that, runs great.

Very good.

For others that search and find your threads in the future, you might want to post up what you did to fix the problems.
