What code(s) did you find when the computer was scanned? Can you post them here? If the light is still on and you don't have the code there, go to Auto Zone and they'll scan it for free and give you the codes. Post them here as a reply/comment, and I can define them for you and give you ideas on what needs to be done. A throttle body is a mechanical item with nothing but air flowing through it. I very seriousy doubt it needs to be replaced.

Testimonial: "Mechanic didn't reveal code just put it back together and the light went out. I'm thinking it's a bit cleaner now and if lite comes on i'll auto zone."

Not getting throttle response. Truck limps Check engine code reads that it is "Throttle body actuator motor." So I replaced the entire throttle body and the symptoms are still there. What is wrong?

You did not follow the diagnostics for the fault code, fault codes indicate what system has a problem but not what particular part of the system, just that a problem exists in the throttle control system. You need to have this diagnosed with a factory scanner

Throttle body

Cleaning the throttle body often fixes this problem otherwise you will likely need to replace the throttle control motor. At the throttle control motor monitor the clutch operation. Check to see if the computer is supplying the clutch circuit with a 12 volt square wave pulse signal. With the key in the on position, check to see if the throttle motor makes a buzzing noise as the throttle is opened and closed. With the key off, push the throttle plate open with your finger and allow it to close. The throttle plate should open and close smoothly.

I have a beautiful 2000 Toyota tundra 4x4 with 208,000. It looks and runs great but the idle needs turned up a little and I also want to change the trasfer case oil, can you tell me which oil is best for...

Pull the intake tube off the front of the engine at the throttle body and clean the gunk out of the throttle body with some carb cleaner and a toothbrush. Be careful where tou spray the cleaner. And make sure you open the butterfly to clean behind it. It should be the first thing to try, since it's the cheapest and easiest thing that I can think of. It worked for me. I had 203,000 on my 2000 Tundra SR5 (V8 - 4WD)

2002 Toyota Tundra Stalls

The throttle body needs cleaning. It has some carbon build up, and when the battery went dead the computer lost its learned values, one of which is base throttle position. Now its reset back to factory specs, not accounting for a dirty throttle body. Seen it a million times

2000 Toyota Tundra - Clutch Sticking

First - Check motor mounts - when you let off the clutch, your truck demands torque from the engine putting pressure on the motor mounts. If your motor mounts are bad, your engine will twist more then normal when release the clutch and it may pull your linkage cables tight to your accelerator. Also - you might check the spring at the throttle body and see if it is sprung or something.
