First make sure you have the right amount of tire pressure in all four tires. Use the specification that is mounted on your door jamb. I believe it is 32 psi. Drive for up to 20 miles. Light should turn off. If light doesn't turn off most liekly you have a bad tire or bad tpms sensor. You will have to take to chevy dealer for tpms diagnosos or some tires shops have tpms sensors scanners

SOURCE: how to reset the tire pressure on a 08' chevy

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:

  1. Set the parking brake.
  2. Turn the ignition switch to ON/RUN with the engine off.
  3. 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.
  4. Start with the driver 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 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.
  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. 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.
  9. 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.

SOURCE: What happens when my check engine light comes on?

Hello. Your vehicle and most other recent ones have on an on-board computer called an Electronic Control Module or ECM. The vehicle computer system has self-testing capability. When the computer senses that there is a problem with some of the components it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and your car needs to be looked at. To properly diagnose what is wrong, you need to take your car to a mechanic or a dealer. The technician at the dealership or a garage will then hook up the scanner to the car computer and retrieve the stored trouble code(s). Then he (she) will look it up in the service manual provided by a car manufacturer. The service manual contains the list of possible codes (about few hundreds) and describes what each code means and what needs to be tested. The code itself doesn't tell exactly what component is defective - it only indicates where to look, what engine parameter is out of normal range. The technician will have to perform further testing to pinpoint a defective part.
Recently many auto parts stores, such as auto zone, offer the free service of scanning your computer and pinpointing the reason why your check engine light comes on. I recommend that you start there as it is free. Regards, Joe

2004 chevy tahoe instrument cluster (parking brake & abs lights don't come on at all. There are no codes either. Are there specific fuses associated with these bulbs in the instrument cluster?


Hello the Chevy and the GMC are bad for the resistors breaking of the dash easy fix, but they are also bad for the pin bulbs burning out. So if you know anyone that can solder this is a cheap fix can get the bulbs on ebay but personally find someone that can do a good job and go with led bulbs they will last longer and better, but with all the issues i see you may want to look into a new cluster

Overactive tire pressure warning light on Honda FIt


the time when you check the tire pressure is before driving it or after is been driven? Reason I am asking this is because the air pressure after use checked would be different from cold start test. as the air after friction expanded and surely is more than the cold.check the tire pressure when cold and see if you are in the limit. If you are and still have the light come on then the problem you have possible are the tire valve sensor. Ask your dealer to check it .

I HAVE A 2008 CHEVY COBALT, THE CHECK TIRE PRESSURE LIGHT IS STAYING ON. HOW DO I GET IT SHUT OFF?


All you should need to do is check and set all tire pressures and make sure to check the spare also, after all tires are set with air you then drive a few blocks and the light should reset if the light does not reset then you will need to find out which wheel has a bad air pressure sensor, this is done with a tool that is put on the valve stem or a scan tool to see which tire is showing the wrong pressure, hope this helps.

Changed right front tire now reads zero on dash light is on


Your tire pressure monitor needs to be reset whenever you change or rotate your tires...

1. check and make sure that your tires are inflated to the correct pressure

2. turn the ignition switch to the ON position. If the low tire pressure warning light comes on, push and hold the tire pressure warning reset switch (think the switch is in the glovebox, but not sure) until the warning light turns off and then release the switch.

3. now press and hold the tire pressure warning reset switch until the low tire pressure warning light blinks three times.

4. initialization is *not* completed until driving at the vehicle speed of 19 mph or over for more than one hour. the tire pressure monitoring starts when initialization is completed.

Sensor light comes on(2008 Dodge Charger)


if the weather has changed and got cold your tire pressure would have dropped and would be lower. 2 options. 1 is fill ther tire to 30 psi and ride it out (remembering that when it warms up the tire pressure will automatically go up too)
2. Is to run a dry air such as nitrogen which does not change pressure in hot/cold weather.
Hope this helps
