Well, ive had a few other threads that have helped diagnose the problem. A lot of people have been saying it's almost never the KS itself, so check the wiring, I checked the sub harness wiring, checked out good, but, I checked the wires from the ECU that plug into the sub harness, and there was some bear wire.

Do you think this is the problem?

In case you couldn't see.

Perhapzzz...

How do I know that the wire in the shielded wiring isn't melted also?

And is it shielded all the way down to the ECU?

nismolism · 07-22-2009, 04:49 PM

you need to test the continuity..lol i dont think i spelled that right...hahaha
no wire that goes to any thing should be bare wire..

I checked the OHM reading on the signal wire, and it was 200ohms, but on the other hand, it get's no volts.

Which stumpts me.

If it's not getting any volt readings does that mean that there is a short somewhere before the plug?

Im also stumped on this part (kinda)

When I reset my ECU, and basically replace the resistor with the Knock Sensor, it only gives my code 34

But, if I have it just plugged into the Knock Sensor, I get codes 12 (MAF) and 34 (Knock Sensor)

Im confused.

I really think it may be shorted out somewhere, and I have no clue on how to fix it.

make new lines or get a new one

nrmskate · 07-22-2009, 06:11 PM

How do I know it's the line though?

and how would I go about re-wiring it?

Where can I find a diagram of a KA24DE ECU Pinout?
