i was driving my car today when a buzzer went off it sounds like either the lights on buzzer or the door openm one, its a constant high pith buzz and it wont stop. there arnt any lights or warnings going on. i just pressure washed the engine bay about a week ago i dont know if that may have some thing to do with it any ideas please help i can hardly standto drive it!

 

Is it constant, or only past ~6500 rpms?

 

its constant. its not the redline buzzer its a different sound. its not overheating, there is oil presure, so im confused.

 

Easy fix, have your radio going full blast all the time.

 

It's probably the low oil level warning buzzer. It goes off when you're a quart low and it's the most annoying sound you've ever heard. Top it off and the noise should go away. Another nasty warning alarm is for low coolant level. It sounds like a loud, tinkling bell. There is a warning light for that, but that does not mean the light is not burnt out or shorted. If nothing is actually low, then it could be the wiring to those sensors.

 

There is an electrical connection down by the driver's side of the radiator. If it gets wet then she'll scream at you for days. I'm not sure what it is exactly, but this is what I've found after a few frustrating instances. Last time it happened, I got a can of ignition wire dryer and hosed that whole area down. Kind of a shotgun approach, but what the hell, it worked!

I tell you though, I'd rather have an 18 inch phillips screwdriver slowly pushed through my skull than have to drive with that noise again! Come to think of it, there probably wouldn't be too much difference between the two. Good luck.

 

where would those sensor wires be?

 

also, it has never backfired at all before, and now that this buzzer is on, it backfires once in a while after givving it gas.....

PLEASE HELP!!!

 

The sensor is in the side of the oil pan, so check the connection there.

 

i was wiggling the wires that come out of the coolant sensor and got it to stop, i think one of the wires may be breaking but thank god it stopped

 

ok blake, so the tinkling bell is low coolant, i think thats what mine is doing...i wasn't really worried about it cause it only does it about 50% of the time, and i was planning on tracking it down and cutting the wires to the buzzer pretty soon...but, if i can just get rid of the low coolant wires right at the sensor (the one on the top of the radiator i assume) then that should take care of my problem. I think its shorted out, or more likely the sensor is bad, but is it common for them to change the dinging pace, its starts kind of slow, then gets fast, then slows down again, there is really no pattern for this but its annoying. So far i've just been using sixstars solution

that'll give me something to do tomorrow i guess
