1G Knock Sensor Wiring

[Stangmurdera]

I pulled the engine out of my car because the piston rings were fried and when I got the motor out, the knock sensor was not even hooked up. There is a wire coming from the sensor that broke off from the harness. I cannot figure out where it came from on the harness so that I can solder it back together or replace the whole sensor with wire. Can anybody help me know where to hook it back up to? Should I just replace the sensor, wire and all? Please help as my new engine is going back in tonight or tomorrow.

If you're pulling the motor for rebuild, it's a good idea to simply replace the sensor assembly and have peace of mind. Consider it safe insurance.

Besides, they're not all that expensive.

Yeah just replace the sensor. That will save you in the long run.

I don't even see in the harness where it plugs up. Can somebody help with that? Where can I get the sensor?

You can order the sensor from the dealer. As far as the harness, I don't have an NT so I can't advise you there. If you don't already have a Chilton's or Haynes manual, pick one up and this will point you in the right direction.

I'm sorry I didn't specify. This is for the a 90 Eclipse GST. The harness wire going to the knock sensor is broken off and I do not see where in the main harness it is supposed to hook to. I should have specified..any other help now will help. I am going to order a new knock sensor but I still need to know where it hooks to in the main engine harness.

i woul say invest in a service manual, so anytime time you have a question of what something looks like or where its at, you can look there. But it should be located on the bracket fot the intake manifold. there should be 2 harnesses there, one for the Knock sensor and one for something else
