Dash says "low Air pressure", Tire gauge doesn't?

[jtfx6552]

What do I do now? Is there away to find which sensor the car thinks is low?

I have 32 psi tire in each at the moment.

My suggestion.

Check another car to ensure the tire pressure gauge is working.

Check the front right tire again. (most common occurrence on my car)

Possibly let a few psi out and try again.

I believe the tires are supposed to be
33 in the front and 35 in the rear.

• For tire pressures, see the placard located on the B-pillar inside the driver’s door.
• Tire pressures are specified cold and should be checked after the vehicle has been parked for at least 3 hours. Do not reduce pressure of warm tires.

The monitor comes on if there is a 3psi difference I believe. It is possible one of them came down (to what you read) but is 3 psi down and trpped it?

NOTE: If the vehicle has been stationary for more than 30 minutes, the sensors will go into a "sleep mode" to conserve battery power. It will be necessary to wake them up so they will transmit the latest tire pressure information to the BCM .

Mine took a few starts before it figured out that the pressure was normal again. Recommended pressure in my door jam is 35psi all around.
