My brother has a 2002 ETH with a comp box and has no throttle most of the time. If he gets it up to speed he can use the cruisecontrol to work the throttle. Got codes from truck they are p0121, p0122 and a p1693. Can any body tell me what to do. He greased up all conections. Still did not work.

Codes

P0121--Accelerator position sensor voltage too low and TPS voltage does not agree with MAP. P0122---Throttle position sensor voltage too low. P1693--DTCdetected in PCM/ECM. bg

Have him disconnect the neg side of both batts for about 30 minutes. Then hook them back up and turn the key to the on position (but do not start the truck). The slowly push the go peddle to the floor and let it back up slowly. Then turn the key to the off pos and back on and start. This is how you recalibrate the TPS and it sometimes helps with this problem. If that does not work you probably have a failed TPS and its off to the dealer you go...
