The low coolant buzzer keeps going off in the car but coolant level is fine. THe wire is fine too, so is there some OTHER warning that will cause that buzzer to go off?

It starts when the key is in the ON position (motor off) and it only stops after the motor warms up???

 

If you did a proper search, you would've found that the buzzer is only triggered by three things.

LOW COOLANT
LOW OIL
REDLINE

Oops forgot to put in the wierd part

It only goes off (being the buzzer stops making noise) after the car has warmed up. Oil level is full.. coolant is full.. and it happens even when motor is off.

 

Just because everything is topped off doesn't mean the buzzer won't trigger?
How about a bad or disconnected sensor?

Everything was working before the TB mod, so im betting disconnected sensor. I just didnt know the extent of sensors that would trigger that buzzer (which i could have found by searching)

SO where is this low oil sensor located?

 

I also have this problem after pulling my UIM off this week. Now it bugs the **** out of me and all of my fluid levels are correct and i didnt touch anything as far as I know, that would effect this

 

if it changes state when warm, you have bubbles in the coolant system.

Pretty cut and dry. Bleed the system.

 

The buzzer only goes OFF (stops making noise) when it becomes warm

 

yep... pretty damm straight forward.

Not getting why you don't bleed out the coolant system.

Have you properlly bled the coolant system???

Or did you just look at the overflow resivoir and figure that because it is between the H and L that the radiator and coolant lines must be fine?

 

A mazda DEALERSHIP (yes, this is going to sound silly) disabled my low coolant sensor because i need a new one and they decided not to fix it. I am going to buy one myself, but untill then i believe they grounded the low coolant wire so it would make the buzzer stop going off.

 

It's a $20 sensor...why would anyone not just fix it???

 

Ask mazda. As for me? Lazyness. Up untill today, i installed a new one and its still buzzing

 

Did you bleed the system??? You never answered that before.
When the engine is cold, and you squeeze the upper rad hose... do you hear air bubbles???

and you posted:
what are you thinking even taking it too the dealer (You didn't take it took Mazda, you took it too a Mazda dealer- whcih couldn't fix these cars when new).

 

My upper rad hose has a metal "spring" lining so you cant squeeze it. How do i bleed the system?

Haha good point.. all i got out of taking it there was a new friend

 

Dang My Buzzer's Been Going Off Lately As Well,ive Bled The System 3 Times With No Luck..then Reted Comes In Here And Say's It Could Be Your Oil Level,well I Just Changed That And It Might Be Low. Thanks!

 

I've posted the following before... *sigh*

The buzzer is for the following

1. Redline
2. Low Oil
3. Low Coolant

It will go off during the following situations according to the previous numbered list.

1. Roughly at/above redline

2. Immediately when the car senses that it has low oil. When your oil is near the absolute low point, it will go off during a turn when the oil shifts and the sensor sees the the oil is low. If the oil is properly filled, the shift won't matter and it won't go off.

3. After ~15 seconds of the car constantly sensing low coolant via the coolant level sensor. It WON'T go off due to a turn unless you're in a sharp turn that lasts quite a while (long on/offramp maybe). Definately not what you're describing.


The loan shark?

 

When I fist put my motor back in my car I had a buzzer going off. I found out that I forgot to connect a ground wire thing by the cluch slave cylinder. Once I hooked it up the buzzer quit going off.
