Is it running in the reduced power mode or just the message?
I ended up checking everything you guys had suggested and it was a no go. Everything looked good, i even had the battery checked and it was good. I borrowed a voltmeter and made sure I was getting power to the connector.
The TAC was bad, the sucky part is I dont know how I broke it??

Once the codes have cleared and if they come back, then either your Throttle Position Sensor or Throttle Actuator is bad.Like what was mentioned above... The Throttle Actuator is a fragile piece once it has been removed. Can't really explain why it gets messed up--just know that it is a high possibility once those codes are thrown.

im having the same issue with an 02 escalade ext. clear the code then start the truck it will idle okay for a minute or 2 then go into REP, i get code 1515 and 1516, if i put the truck at about 1000rpms it wont go into REP. i had taken the intake tube off and was cleaning the TB while a buddy was opening the butterfly with the pedal in the truck, he said something about it going into REP but i didnt think anything of it at the time. i was using brake clean so im not sure if i got it on one of the sensors while the batter was connected and screwed it up. i ended up taking the TB off the truck cleaning it up and reinstalling it, with the battery connected and key on the TB was not getting any signal from the pedal. once i cleared the codes it worked but will still go into limp mode. i have checked the battery with a volt meter and it is 14 volts with the truck off. checked the wires all the way from the 2 sensors on the TB to the back of the intake. pulled hard and non stretched. checked both grounds on block not those either. should i just replace the sensors or buy a whole new TB. id use the one off my 04 SS 6.0 but it only has 1 sensor where the escalade is an 02 and has 2 sensors. any thoughts?
