What should the gauge on the electric compressor read for the standard Dunlop tires when properly inflated? How accurate is that gauge?

I'm having a bit of an odd problem with my Tire pressure sensor in as much as it will light up.. and stay lit for about 3 minutes and then go out so I'm assuming that one of my tires is a little low on pressure but when the tire heats up the pressure rises and so the light goes out. Is this a valid assumption to make or does this indicate something more serious?

Anyhow.. any/all answers would be most welcome!

Cheers..

Dont rely on that gauge it is an emergency use only last resort. Go to auto parts store or Wal-mart and buy a gauge for under five bucks. I always have two on hand and check them together once in awhile to see if they are the same. They can get droped or damaged and go out of wack. Check them in the morning when they have cooled down and make it 32psi your lite will not come on again.

 

Yep. What Old Rotor said. Do not trust that Mazda guage on the air pump.

 

Folks,

I recently had a low tire, turns out it had a nail in it. I didn't get any warning from the TPMS at all.

Turns out that was for good reason, seems mine is not equiped with the system according to my Canadian Mazda dealer.

I was under the impression that the only option on a 2004 GT was the NAV package. Can anyone shed some light on this issue?

 

tpms is a US FEderal requirement not a canadian one. you dont have them.

 

ditto the suggestions on getting your own seperate gauge.
I also agree that your tires are heating up and coming up to the correct pressure as you drive a bit.

 

CAUSES OF A TPMS MIL & WARNING BUZZER

Aftermarket wheels or factory replacement wheels installed without wheel sensors

Tire pressures were adjusted with tires hot, light comes on when vehicle is cold. (Tire pressures must always be adjusted cold)

Low air pressure in any or all wheels {below 179.26 kpa (26 PSI)}

High air pressure in any or all wheels {above 337.84 kpa (49 PSI)}

Spare tire installed on vehicle

Instant Mobility System repair agent or fix-a-flat was used and is clogging a wheel unit
NOTE: The TPMS system will turn the warning lamp off after the vehicle is driven over 25 KM/h (16 MPH).

Example: If you correct tire pressure after repairing a flat tire, or reset tire pressure to the proper range, (such as at PDI to correct high shipping tire pressures), the TPMS warning light will stay illuminated until the vehicle is driven over 25 KM/h (16 MPH).

TIRE PRESSURE ADJUSTMENT

Using a "stick" or other mechanical air pressure measuring gauges may not provide accurate results. Mazda recommends using a digital type gauge for best results. Example: Accutire model #) MS-4000.

Funny thing. I spent 25 to 35 dollars on a good gage for my motorcycle and the tire pump gauge that comes with the car is always accurate.
