Welcome to JA!
Here is what will trigger the light.
high coolant temp
high oil temp
low oil presser
id go threw check the fluid levels
if there is good oil presser and fluids are full
Most of the time its a faulty low coolant level switch
i would go threw and unplug then plug in the sensors and switches
Let me know if i can help more!
How can i help you.
Hi there is nothing on the fuel system to tiger a warning buzzer
is there a sensor on the oil pan?
The only thing other then my original posting on the trigger of the alarm would be the TPS throttle possion sensor, But there showing a hard code with the buzzer and light,
Could very well be a intermittent problom so it wont hold a code.
My wording was wrong on that sorry
yes on the buzzer and light but a check engine light would stay on even with the buzzer off, ,,,,,,,,,,,,,, but if its a intermittently problom like the brass contact on the TPS then i don't think it will hold a code, I would check that.
If it were a hard code for the tps it would have a check engine light on all the time.
and have a code showing 33-145,
A soft code is when it don't last long enough to store in the ecm example is a bad spot on the brass on the ecm so at a certain time during throttle presser it will flash a check engine light and buzz, when you move the peddle it changes the voltage on the tps so all you get is a quick flash of a code,
Let me know if your still having problems!
