Good morning,

I attached the location of the throttle body. It is on the end of the upper intake manifold. It is held by 3 bolts, an electrical connector, and a hose.

There is no relearn for this. It is a plug-and-play replacement. I attached the part as well for you.

Thanks Asemaster6371. I'm going to change it and let you know what happened. If the PCM is bad, it can cause that the accelerator actuator at the throttle body do not respond? I have the signal from the pedal, but something it's wrong.
The code that I pull out from the scanner is p2101.
Thanks,
Juan Marin

Hi. I change the throttle body but it didn't work. Does not accelerate. I have a signal from the acceleration pedal. I looked for the connection for any damage, but everything looks fine. Is there any relay that controls the throttle body? Can you send me how to test the ECM to see if it's working correctly?
Thank you,
Juan Marin

Okay, do you have an advanced scan tool that can read the commands to the throttle body?

I attached the wiring diagram of the system for you. I highlighted the wires for you of the throttle body and the pedal sensor.

I also attached the flow chart for the throttle body operation.
