2010 Acadia, tire sensor showes low air (not low) drivers seat does not go back or forward. Tire signal goes away and seat works, then goes bad again .

The sensor in the tires takes a battery and the battery might be bad or the tires were filled with air that has too much water vapor in it and the sensor is affected by the water.

It is possible that the sensor just needs to be reset. Any place that installs tires should be able to do this for you. If that doesn't work then I would have to say the sensor has been damamged or just gone bad. Hope just getting things reset helps.

Best to have the vehicle checked out by a mechanic if it comes back on. Also if you where driving in wet weather that's a possible reason for the light to display. Al s of double che c k air pressure in tire all the way around the vehicle

That signal is from your tire monitoring sensors, telling you that there is air pressure difference between tires. The tire pressure should be same in all tires.

There is a Technical Service Bulletin (TSB) for your vehicle stating that if the light is blinking and if there are dashes (- -) on only one or two tire pressure readings, then the tire presure monitoring system should be put through a "Relearn" or "matching" process. Then if any of the tire pressure sensors do not respond while relearning, the sensor in that tire should be replaced.

The TPMS matching process is outlined below:

1. Set the parking brake.
2. Turn the ignition switch to ON/RUN with the engine off.
3. Go to the TPM vehicle information screen on the DIC. Press set to relearn the sensors. The horn sounds twice to signal the receiver is in relearn mode and Tire Learning Active message displays on the Driver Information Center screen.
4. Start with the driver side front tire.
5. Remove the valve cap from the valve stem. Activate the TPMS sensor by increasing or decreasing the tire's air pressure for 10 seconds, or until a horn chirp sounds. The horn chirp, which can take up to 30 seconds to sound, confirms that the TPMS sensor identification code has been matched to this tire position.
6. Proceed to the passenger side front tire, and repeat the procedure in Step 5.
7. Proceed to the passenger side rear tire, and repeat the procedure in Step 5.
8. Proceed to the driver side rear tire, and repeat the procedure in Step 5.
9. After hearing the confirming horn chirp, for the driver side rear tire, the horn sounds two more times to signal the tire learning mode is no longer active. Turn the ignition switch to LOCK/OFF.
10. Set all four tires to the recommended air pressure level as indicated on the tire and loading information label.
11. Put the valve caps back on the valve stems.
The tires air pressure will not appear on the screen until you start driving the vehicle.

Make sure you refill the tires with the specific amount of air and if it doesnt make the light go away you got a bad tire pressure sensor.
Please dont forget to rate me..

The yellow exclamation mark appears when your TPMS, AKA tire pressure monitoring system picks up on a low-pressure tire. It means that your tires aren't inflated to the recommended pressure. A simple fix is to inflate to the required PSI, and if the problem does not go away, drive down to the nearest garage, as you may have punctured tire at your hands.

If its reading low and the tire pressure is correct there is a problem with that sensor. Typically they need to be replaced in order to correct the problem. A TPMS tool capable of displaying TPMS sensor data would confirm the bad reading.

They display the tire pressure as a convenience. They don't have to display the pressures and many makes/models do not.

The level of sophistication with these systems is slowly improving. Many newer models will automatically know where the tire is and display it correctly. Unfortunately yours need to be relearned manually after every tire rotation which is very common with earlier systems. It is assumed that this is done after every tire rotation which would then make the displayed tire locations correct.

If you are confident that the correct tire location is being displayed than I wouldn't see any issue with replacing that sensor. If you are not confident the correct tire location is being displayed than it wouldn't be a bad idea to do a relearn procedure.

The TPMS matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to ON/RUN with the
engine off.
3. Press and hold the Remote Keyless Entry (RKE)
transmitter's LOCK and UNLOCK buttons, at the
same time, for about five seconds to start the TPMS
learn mode. The horn sounds twice indicating the
TPMS receiver is ready and in learn mode.
4. Start with the driver side front tire. The driver side
front turn signal also comes on to indicate that
corner's sensor is ready to be learned.
5. Remove the valve cap from the tire's valve
stem. Activate the TPMS sensor by increasing
or decreasing the tire's air pressure for about
eight seconds. The horn chirp, can take up to
30 seconds to sound. It chirps one time and then
all the turn signals flash one time to confirm the
sensor identification code has been matched to
the tire/wheel position.
6. The passenger side front turn signal comes on to
indicate that corner sensor is ready to be learned.
Proceed to the passenger side front tire and
repeat the procedure in Step 5.
7. The passenger side rear turn signal comes on to
indicate that corner sensor is ready to be learned.
Proceed to the passenger side rear tire and
repeat the procedure in Step 5.
8. The driver side rear turn signal comes on to
indicate that corner sensor is ready to be learned.
Proceed to the driver side rear tire, and repeat
the procedure in Step 5.
9. After hearing the single horn chirp for the driver
side rear tire, two additional horn chirps sound
to indicate the tire learning process is done.
Turn the ignition switch to LOCK/OFF.
If no tires are learned after entering the TPMS learn
mode, or if communication with the receiver stops, or
if the time limit has expired, turn the ignition switch to
LOCK/OFF and start over beginning with Step 2.
10. Set all four tires to the recommended air pressure
level as indicated on the Tire and Loading
Information label.
11. Put the valve caps back on the valve stems.

When you "fill" the tires they must be within 3 lbs of each other or the tire pressure warning light will come on. If the tires are "filled" correctly and the tire pressure light still comes on, you may have a tire pressure sensor that has gone bad. You would then have to take your car in to the dealer or tire shop to determine which tire sensor is bad.
Good luck.

could be low tire pressure or anti slip traction control was working. turn of your traction control and the light will stay on... or read your owners manual
