Part Numbers for these items?
Does anyone know the part numbers for the throttle pedal assembly and the TB itself for an 07 5.3L Suburban? Our local dealer provided me a quote but would not provide the part numbers. Thx in advance. RL

Welcome to the forum... you might try OEHQ.com or GMpartsdirect.com...
look up the part, add it to your cart and many times the part number is listed...

TBS error codes
I am also getting 2 error codes for the TBS on my 07 Tahoe. But the gal at AutoZone said they couldn't get the part. Is this something I have to go through my dealer for?

The new body style trucks that are drive by wire frequently will show a higher idle after cleaning the throttle body.
What happens is that as the grime and carbon builds up, the computer sees a different position for the throttle body and the throttle position sensor. By cleaning the throttle body, all of a sudden the computer thinks the sensor is supposed to be in one position, but it is actually closer to closed. Therefore, you get the high idle because the computer does not register the true position of the throttle body.
Many times, as seen in previous responses, the computer will relearn the throttle position. I have also seen an idle of 2,000 rpm because of the misalignment of the TPS. This is not safe to drive until it is relearned; imagine sitting with both feet on the brakes at every stop light.
Immediately after cleaning a throttle body or throttle position sensor on any drive by wire vehicle, you should hook up a scan tool and relearn the throttle position sensor location. This will give you proper idle speed, as well as improve gas mileage because the computer will set new idle air control parameters.
There are a number of Service Bulletins in GM info for this procedure.

I have a 2007 Tahoe LTZ that has the engine light on. When I went to the parts store and they put the code reader on, it showed a "throttle position sensor". I've been absolutely everywhere to purchase the entire throttle body (I've been told you have to replace the entire assembly) but there aren't any available anywhere- can't even order them. Has anyone else encountered this and if so, what can I do???
