check out this video, looks like the intake is coming off. you could get one at autozone, napa,or oriliys. if you have the money it wouldn’t be a bad idea to get it at the dealership. just had it do a job on my car twice because the part I received was defective. good luck.

Often times you can get the part cheaper online. If I don’t need the part right away and have time to wait for it to be shipped I order on rockauto.com. Great place for parts!

Are you absolutely certain the knock sensor is bad or is this an educated guess?

[stephen]

yes they are bad so the scan tool told me

There is a service bulletin on your problem. I forget what it was but I will try and find it for you.

[college man]

you may want to do the knock harness also.

what is the stuff to get around the knock sensors cuff to keep water off of the sensors

[Shaun_300]

Knock sensors are fairly common on these. I recommend changing the two knock sensors and the harness to be safe, as stated above the intake manifold has to come off. Not a real hard job by any means. One tool you may not have is the fuel line disconnect tool. Yours being a 2000 you’ll need both the 5/16″ and 3/8″ since it has the return style fuel system.

This is partially what the TSB says about your problem.

After you replace the sensors, the TSB relates to those who have been washing their engines a lot. According to the TSB you have to pull the intake manifold and put a ring of RTV silicone around the knock sensor and replace the sensor.

I think this keeps the water from sitting around the sensors and rusting them out.
