Hello, It sounds like you have a bad sensor. If you put air in tire and have not driven the car the drive it first (about three miles) The sensors are part of the valve steam. To activate them you have to drive the car.

HOW TO RESET THE LOW TIRE LIGHT


sounds like a sensor problem. if all tires are correct on pressure, the light should have gone out. heres how to trouble shoot this problem,
1) Inflate all the tires to the recommended pressure
2) Turn IGN to RUN, but do not start engine.
3) Starting at the left front wheel, deflate the tire to 20-psi. Wait 2-mins. A fault should set once the tire reaches 20-psi or within 2-mins. If the fault sets, re-inflate the sensor and repeat the test sequence at each wheel until you find the wheel that does not properly set a fault warning.

I changed 1 of my valve sensor so i need to no how to reset the tpms light


By operating the tire pressure warning reset switch, the tire pressure warning ECU can be set to issue a warning at an inflation pressure that corresponds to the standard pressure of tires .Therefore, you must set the warning threshold to the proper value in order to comply with the local regulations .Operate the tire pressure warning reset switch only after the inflation pressures of all tires have been adjusted on the vehicle.To initialize the system, press and hold the tire pres- sure warning reset switch for 3 seconds or longer with the ignition switch in the ON position. When the system receives the
initialization signal, the warning light blinks 3 times (1 second on, 1 second off). During initialization, the tire pressure warning valve and transmitter measures the inflation pres sure of the tire, and registers the signals that are transmitted into the tire pressure warning ECU at a frequency of once per minute. The initialization process is completed when signals from all the tires have been received. It takes a few minutes .

I switched tires on my 07 GMC sierra the orgional tires have a max of 44 psi and the new ones have a max of 80 psi i aired them up to 65 psi and now its telling me to check tire pressure


Hello: Do not go by the pressure printed on the tires. On the drivers door frame or door sill there is a white tag that gives the recommended tire pressure for the truck. If tire(s) are over inflated or under inflated the light will come on........ Once you get the proper pressure in the tires and drive it the light should go out. If when the new tires were installed they didn't put the wheels back in the same position the the location of each wheel will have to be reprogrammed into the system.

All four tires are wearing out on sides of tires


If the tires are wearing on both sides and not the centers, instead of just one side per tire then the tires are under-inflated. Inflate to the proper psi.
If the tires are wearing only on one side, ie, left side tires wear on the left side, right side tires wear on the right side or vice versa, then the alignment is off, adjusting the camber may fix the problem.

Left front Tire Pressure Low Warning , Tire Pressure Good Scroll Though Menu and Indication on Dash reads 1 psi is it the wheel sensor or does the sysytem have a nother fault or require recalibrated


Have you rotated tire positions? Anyway, if all tires seem to be physically stable, give it a few more runs and another mileage. The 1 psi reading should increase and improve significantly. If not, it is best to have your tires recalibrated, from there you can easily determine if that sensor is at fault or not.

Service tire monitor on what is the problem? how do you reset the system?


TIRE PRESSURE MONITOR SYSTEM
The Tire Pressure Monitor System (TPMS) uses radio and sensor technology to check tire pressure levels. If your vehicle has this feature, sensors are mounted on each tire and wheel assembly, except the spare tire. The TPMS sensors monitor the air pressure in your vehicle's tires and transmit tire pressure readings to a receiver located in the vehicle.

The TPMS is designed to alert the driver, if a low tire pressure condition exists. This system also allows the driver to check tire pressure levels using the Driver Information Center (DIC).

When a low tire pressure condition is detected, the TPMS displays the "CHECK TIRE PRESSURE" warning message on the DIC, and at the same time illuminates the low tire pressure warning symbol.

You may notice, during cooler weather conditions, that the tire pressure monitor light, located on the instrument panel cluster, and the "CHECK TIRE PRESSURE" message will appear when the vehicle is first started and then turn off as you start to drive the vehicle. This could be an early indicator that the tire pressures are getting low and need to be inflated to the proper pressure.

Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper inflation pressure for those tires.)

As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated.

Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability.

Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale.

The "CHECK TIRE PRESSURE" warning message and low tire pressure light (telltale) will appear at each ignition cycle until the tires are inflated to the correct inflation pressure.

The Tire and Loading Information label (tire information placard) shows the size of your vehicle's original tires and the correct inflation pressure for your vehicle's tires when they are cold.

Your vehicle's TPMS can alert you about a low tire pressure condition but it does not replace normal tire maintenance.

NOTICE: Do not use a tire sealant if your vehicle has Tire Pressure Monitors. The liquid sealant can damage the tire pressure monitor sensors.

RESETTING THE TPMS IDENTIFICATION CODES
Each TPMS sensor has a unique identification code. Any time you rotate your vehicle's tires or replace one or more of the TPMS sensors, the identification codes will need to be matched to the new tire/wheel position. Each tire/wheel position is matched to a sensor, by increasing or decreasing the tire's air pressure. The sensors are matched to the tire/wheel positions in the following order: LF TIRE (left front tire on the driver's side of the vehicle), RF TIRE (right front tire on the passengers side of the vehicle), RR TIRE (right rear tire on the passengers side of the vehicle), and LR TIRE (left rear tire on the driver's side of the vehicle).

You will have one minute to match the first tire/wheel position, and five minutes overall to match all four tire/wheel positions. If it takes longer than one minute, to match the first tire and wheel, or more than five minutes to match all four tire and wheel positions the matching process stops and you will need to start over.

The TPMS sensor matching process is outlined below:
  1. Set the parking brake.
  2. Turn the ignition switch to "RUN" with the engine off.
  3. Turn the headlamp switch from "OFF" to the parking lamps setting four times within three seconds. A double horn chirp will sound and the TPMS low tire warning light will begin to flash. The double horn chirp and flashing TPMS warning light indicate that the TPMS matching process has started. The TPMS warning light should continue flashing throughout the matching procedure. The "SERVICE TIRE MONITOR" message will be displayed on the Driver Information Center (DIC).
  4. Start with the driver's side front tire.
  5. Remove the valve cap from the valve cap stem. Activate the TPMS sensor by increasing or decreasing the tire's air pressure for 10 seconds, then stop and listen for a single horn chirp. The single horn chirp should sound within 15 seconds, confirming that the sensor identification code has been matched to this tire and wheel position. If you do not hear the confirming single horn chirp, you will need to start over with Step 1. To let air-pressure out of a tire you can use the pointed end of the valve cap, a pencil-style air pressure gage or a key.
  6. Proceed to the passenger's side front tire, and repeat the procedure in Step 5.
  7. Proceed to the passenger's side rear tire, and repeat the procedure in Step 5.
  8. Proceed to the driver's side rear tire, and repeat the procedure in Step 5.
  9. After hearing the confirming horn chirp for the left rear tire, check to see if the TPMS warning light is still flashing. If it is, turn the ignition switch to LOCK to exit the sensor matching process. If the TPMS warning light is not flashing, the five minute time limit has passed and you will need to start the process over beginning with Step 1.
  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 spare tire does not have a TPMS sensor. If you replace one of the road tires with the spare, the "CHECK TIRE PRESSURE" message will be displayed on the DIC screen. This message should go off once you re-install the road tire containing the TPMS sensor. The "SERVICE TIRE MONITOR" message is displayed when the TPMS is malfunctioning. One or more missing or inoperable TPMS sensors will cause the service tire monitor message to be displayed.

Warning light under the D on the dashboard


This symbol is the tire pressure indicator. If you are running the factory stock tires on the car then inflate your tires to between 36 and 44 lbs. 44 lbs is max pressure so you would be safe running around 38 or 40 lbs. Once you do this then turn your vehical off and restart it. It should reset the sensor and show enough tire pressure to turn the sensor off.
