SOURCE: airbag light stay on 2003 chevy tahoe

The air bag light will remain illuminated if a fault has been detected in the air bag system.
The onboard computer will need to be interfaced with diagnostic equipment to read the fault.
This is also the only way to reset the light.
Good luck, I hope this helped.

SOURCE: How to clean throttle body on 2002 chevy trail

Instructions for doing it without removing the throttle body.

1. Disonnect the battery....very important so your stepper motor isn't ruined when moving the butterfly.
2. Remove the plastic resonator on the top of the engine (The black piece that says 4200 on it)
3. Remove the large rubber hose from the throttle body.
4. Clean away, with throttle body cleaner or Seafoam, I just use the blue shop towels to clean in there. Could use a plastic bristle brush also for more elbow grease. Be very careful, as the butterfly will cut you very easily, very sharp edges. Make sure you get all the gunk out of there, including any edges of gunk that may have formed, preventing the butterfly from opening and closing properly. Needs to be nice and shiny.
5. Hook the resonator and hoses back up, don't forget the little pcv hose on the front right corner of it.
6. Hook the battery back up and drive around for 20 minutes or so with all accesories OFF. The computer will relearn a properly functioning throttle body at that point.
7. Enjoy a little bettery gas mileage and horsepower.

2003 chevy trailblazer engine dies when ac/heater switch is turned on but blower motor is unpluged

The throttle body needs to be cleaned, grime in this area prevents the throttle plate from closing completely and allowing air to enter, making the air/fuel mixture lean. Make sure to clean the front and back sides of the throttle body. Also, disconnect the battery during the cleaning process to allow the computer to reset and relearn to the cleaned throttle body.

Have 2003 chevy tahoe with codes p220 and p120 also p1516 already replaced the throttle body accuator and still come up with the code p1516

There is a Tecnical Service Bulletin (TSB) that specifically addresses codes P0120, P0220, and P1516.

It says that the TAC Module can set these codes erroneously under certain conditions. It is very likely that if your vehicle is diagnosed according to the provisions of this bulletin, the problem can be corrected without having to purchase or replace any parts.

It is Technical Service Bulletin number 03-06-04-032
Issued June 16, 2003

My 2003 Chevy Tahoe idles very low. When driving at low speeds when not pushing on the excelarator the tahoe will die. It will even die sometimes when the vehicle is in reverse. it does when making...

You may need to clean inside the throttle body. YouTube has videos on how to do it. Also, your Idle Air Control motor might have carbon build-up in the passage for idle air. Take the motor off, and clean it gently and check the air passage for blockage.

Where is the tps on 2003 chevy tahoe 4.8 v-8?

It is mounted to the throttle body where the air comes into the intake manifold it is round and black and has wires going to it. You may have to remove the air intake tube at the throttle body at the top center of the engine to change it. It has to be adjusted properly make sure you mark the position so you get it back the same spot
