Tire pressure indicator light issue

[Rupp]

Guys,
My drivers side rear tire pressure light lights up at 34 PSI event though the other 3 at the same pressure do not. It will eventually reset but is this a sign that this sensor is going out?

Could be or it could be that the tires are low then increase pressure after heating up from driving. Check with an actual tire pressure gauge.

I added air as it did need it but what is odd is they all had identical pressures yet only the drivers rear showed red.

If you allow your tire pressure to get the red warning, it must be pumped back up to the recommended pressure rating before the red light warning goes away, even if you have other tires below that pressure without the warning.

If you see red, pump it up to the recommended pressure (as per your door jam sticker), once the red light goes away you can allow it to go down again without the warning.

Happens to me every so often. On trucks besides Rebels if the psi drops to 29 the warning comes on, needs to see 36 again for it to go off
