Ok so I'm sure its not low, and its a short. I've grounded the wire and nothing. I'm still getting the buzz. but it does go on and off and usually if I make a right hand turn. I'm going to replace the whole engine side, and possably the whole wire if I don't have to tear apart the dash.

So thats my question after it leaves the engine bay where does the wire go?

Please help. this sound is killing my ears!!!

I understand thats where the wire is in the engine bay. what I cant find is F42 on the inside. where does it go to once its inside the car. I just don't think the short is inside the engine bay. so id like to replace the whole wire.

 

Check the page below where it itemizes all the different plugs in that particular diagram. It looks like it connects into me-2 #12 which is the combination meter

 

The low coolant buzzer and the low oil buzzer are the same exact thing. So make sure your oil is topped off. I know when my oil gets a little low the buzzer goes off during turns.

 

As posted by Hailers,


The coolant sensor will cause the buzzer to come on, if it does not see water in the radiator for 10-13 seconds.

The buzzer and light will go off, if the wire is put to ground, within a second. No more. No less.

There's no trick to this. If the key is ON or better the buzzer will come on in 10-13 seconds if the sensor does not see water and the buzzer will go off if it sees water within one second or will go off if you gnd the wire.

If you grounded the brown wire and the buzzer/light didn't come on, then there is probably an open in the circuit. You can prove that one way or the other. Put the key to ON. Measure the voltage at the brown wires terminal that connects to the sensor. It should read approx a half volt dc.

If it does not, the find the connector b/t the sensor and the gauges called FME-01, and find out where the wire is open. It's either b/t the combination meter and FME-01 or b/t FME-01 and the sensors terminal.

 

I replaced the wire it went away. I think it was shorting where the radiator meets the body as it was sanwiched between that part. I pulled it cut it and replaced it. my ears are recovering from this problem as we speak.
