Coolent sensor buzz does not turn off. Coolent is full. So I took some pictures of the wiring on the drivers ide of the engine. maybe I have something wrong but i dont think so. One plug is comming from under the engine with white plug on it. This goes to a plug on the wire bundle also with white plug? I have a wire with not mate It is brown w/white stripe. Think it had a black plug. This wire comes off the bundle and is short. lastly I have a brown wire coming over top the engine to a sensor above the rear top spark plug? Hope I have something wrong here to explain whats happening. Thanks guys.

You are barking up the wrong tree there so to speak... That is the knock sensor!

Download the Factory Service Manual (FSM) from the sticky in this forum and look for the location of the coolant level sensor.

There is also a really good detailed thread about the Cooling System and troubleshooting in the FAQ thread also stickied in this forum.

the coolent sensor is fine as far as the one in the front of the engine. The sensor has two wires. One near the power steering pump. Thats what I am trying to figure out.

I changes both sensors for the coolent. The one at the filler car and the otherrear of motor Like stated earlier. The one in the rear has a brown wire with white stripe. I belive it is called the coolent level disconnect. Still get the beep. I noticed that I did not lose anycoolent while changing the coolent level disconnect. Is that typical? Everything seems hooked up properly. Except for the brown wire coming off the starter harness pictured above.

Dude. You really need to look at the FSM and read the FAQ thread. It has full diagrams of where everything related to cooling is so you can properly troubleshoot. That one on the side is the knock sensor.

He's trying to find the wire c00lduke refers to in this thread:

trust me my friend I do not speak pf knock sensor. I have looked at the fsm and wiring diagrams. I am confused because everything seems hooked up properly. I just have one wire (brown w/white stripe) that dosent seem to go anywhere. I am not someone who haesnt search and also is not an idiot. 1fastt2 is helping me with this you can search and find that he is no idiot either. mahjik you sent me a link to a picture of a labeled wire harness. Do you have the same thing but for the starter power harness?

Sorry, I have not seen anyone remove that harness and then map out the connectors like the engine/emissions harness. It might exist, but I haven't seen it.
