How to Reset the Tire Pressure Monitor on the 2007 Chevy Silveradoby Justin Cupler
Chevrolet got a head start in vehicle safety, as its 2007 Chevrolet Silverado came standard with a tire pressure monitoring system. In the following model year, the National Highway Traffic Safety Administration passed a law requiring manufacturers to fit TPMS on all of their passenger vehicles. There are two reset procedures for the 2007 Silverado's TPMS. The first, and most common, procedure is to adjust the tire pressure if it is low. The second procedure is to relearn the position of each sensor, which you only need to do if you have rotated the tires or replaced a sensor.
Adjusting Air Pressure
Allow the tires to cool for approximately three hours, if you recently drove the truck farther that one mile. This allows the pressure inside the tire to return to its normal rating – heat increases the pressure inside the tire.
Open the driver’s side door and find the vehicle information placard – the sticker containing information about your Silverado. Find the tire pressure specifications on this placard and note them – the Silverado has a wide range of pressures, depending on options, so this is the most reliable method of determining the correct pressure for your truck.
Park the Silverado near a compressed air source. Unscrew the caps from all four valve stems – the black rubber valve protruding from each rim. Set these caps in a secure area to prevent losing them.
Check the air pressure on each tire by firmly pressing a tire gauge onto the top of the valve stem – the brass part – and checking the pressure reading giving by the gauge. Make a note of all four tire pressures and compare them to the correct pressure. Tires that are 2 or more psi lower than the recommended pressure need air added.
Press the air chuck on the air hose connecting to the compressed air source onto the top of the valve stem on a tire that requires air – this starts the flow of air into the tire. Estimate the amount of time to hold the air chuck on the valve stem using the assumption that the tire increases 1 psi every three to five seconds you hold the air chuck on the valve stem.
Remove the air chuck from the valve stem and recheck the pressure in the tire.
Repeat Steps 5 and 6 until the tire pressure is within 2 psi of the recommended pressure.
Repeat Steps 5 through 7 on to adjust the pressure on any other tires that require additional air.
Drive the Silverado as you normally would and observe as the “Low Tire Pressure” message – on the driver’s information center – extinguishes.
Relearning Sensor Position
Turn the ignition to the “On” position, but do not start the Silverado. Remove the valve stem caps from all four valve stems and place them in a secure location.
Initiate the tire pressure monitor learn mode by simultaneously pressing and holding the “Lock” and “Unlock” buttons on the keyless entry remote until you hear a double horn chirp and see the left turn signal flash.
Alternatively, if your Silverado does not have keyless entry, press and release the “Info” button on the driver’s information center until “Tire Learn” appears on the DIC display. Press and hold the “Set/Reset” button. Listen for a double horn chirp, indicating entry into the TPM learn mode.
Press the button inside the top of the valve stem on the left (driver's side) front tire with a small flat-head screwdriver to start the release of air from the tire. Release the air for 8 to 10 seconds and remove the flat-head screwdriver to stop the flow of air. Listen for the horn to chirp – this may happen up to 30 seconds after you stop releasing air from the tire. The chirp indicates the TPMS computer has learned the position of this sensor.
Repeat Step 3 on the remaining three tires, in the following order: right front, right rear and left rear. After the chirp following the left-rear tire, the TPMS computer automatically exits the learning mode.
Turn the ignition to the “Off” position. Check and adjust the tire pressure following the procedure outlined in the section titled “Adjusting Air Pressure.”
