Detail: How to reset the tire pressure on a 08' chevy tahoe?
Solution: TPMS Sensor Matching Procedure 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. The sensors are matched to the tire/wheel positions in the following order: driver side front tire, passenger side front tire, passenger side rear tire, and driver side rear tire using a TPMS diagnostic tool. See your dealer/retailer for service. The TPMS sensors can also be matched to each tire/wheel position by increasing or decreasing the tire's air pressure. If increasing the tire's air pressure, do not exceed the maximum inflation pressure indicated on the tire's sidewall. To decrease 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. You have two minutes to match the first tire/wheel position, and five minutes overall to match all four tire/wheel positions. If it takes longer than two minutes, 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 need to start over. The TPMS sensor matching process is outlined below: Set the parking brake. Turn the ignition switch to ON/RUN with the engine off. Press the Remote Keyless Entry (RKE) transmitter's LOCK and UNLOCK buttons at the same time for approximately five seconds. The horn sounds twice to signal the receiver is in relearn mode and TIRE LEARNING ACTIVE message displays on the DIC screen. Start with the driver side front tire. Remove the valve cap from the valve cap stem. Activate the TPMS sensor by increasing or decreasing the tire's air pressure for five seconds, or until a horn chirp sounds. The horn chirp, which may take up to 30 seconds to sound, confirms that the sensor identification code has been matched to this tire and wheel position. Proceed to the passenger side front tire, and repeat the procedure in Step 5. Proceed to the passenger side rear tire, and repeat the procedure in Step 5. Proceed to the driver side rear tire, and repeat the procedure in Step 5. The horn sounds two times to indicate the sensor identification code has been matched to the driver side rear tire, and the TPMS sensor matching process is no longer active. The TIRE LEARNING ACTIVE message on the DIC display screen goes off. Turn the ignition switch to LOCK/OFF. Set all four tires to the recommended air pressure level as indicated on the Tire and Loading Information label. Put the valve caps back on the valve stems. , The Key to sucsess is to let out about 5 seconds of air then stop and wait for horn cherp. Don't keep letting air out until cherp. Do this for all tires in the correct order, LF,RF,RR,LR. , Hi, a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

Order an owners manuel for the car as there is a lot of info you might be interested in , you cannot do it yourself,either contact a gm dealer or possibly a tire store-there is a little hand held remote that you have to set up against each individual tire to recalibrate the sensors , look in one of the fuse box there should be a red reset button pres on it for about 10 sec. with the car running that should corect your probm. , tahoe 2007 tire press problem
