    i have a 2005 670 volvo tractor.i have recently started having a problem with a stop light on my dash with a buzzer that goes off everytime i start driving my tractor.i have made sure that the park brakes are pushed in and my trailer brakes are pushed in.my tractor is a automatic one.i have changed my brake service valve thinking it was a air leak.but it still is giving me the alarm everytime i drive but when i stop it goes off.every mechanic i asked about the problem dont know the answer for the problem.this is my last resort i hope someone has had this problem and fixed it.thanks

    Are you sure it's not the engine shutdown light coming on? Coolant and oil level would cause buzzer to come on as a pre-warning.

    It a sensor on your air panel behind your clutch pedal.

    any body else figure this out yet? my 05 volvo is doing the same thing... checked oil checked coolant everything seems to be in order... mark69 you mentioned a sensor on a air panel behind the clutch... i dont see nothing there? is it up under the dash? or is it the air distribution manifold on the firewall?

    any help would be appreciated on this please!!!

    Mark's right. on firewall connects with a push pull type connector, it's about 2-3" long and about as big around as a quarter in the center.

    so that is the sensor that tells computer that air pressure is up or is that sensor specific to the parking brake air? thank you guys for all the help on this matter!

    It is the brake sensor on the panel behind the clutch petal. Easy fix.
