Prolong Posted July 3, 2013 Report Share Posted July 3, 2013 I decided to go scan my truck today and clear the codes to see how long it would take for the REP to start back up. Turns out I don't have the U0107 code anymore and now I know what wire it is. It's the wire from the gas pedal sensor to the TAC module. I'm getting a "too high voltage" on those wires. I'm guessing since I soldered them it's causing this. Well does anyone know the name of this wire and where I can buy it at? Quote Link to comment Share on other sites More sharing options...
battousai Posted July 3, 2013 Report Share Posted July 3, 2013 what code do you currently have? and what did you solder? if you soldered the wire to itself, that would not cause the high voltage code. Quote Link to comment Share on other sites More sharing options...
Prolong Posted July 3, 2013 Author Report Share Posted July 3, 2013 P2135P1516P0220 It use to only be the U0107 code but now thats gone I got these 3. And that the only wire I have soldered. The one from the TB Ive re cut and put my old one back and and still only get these 3 codes. So I'm thinking it has to just be that wire.

The one from the TB Ive re cut and put my old one back and and still only get these 3 codes. So I'm thinking it has to just be that wire. there is a GM bulliten on those codes, i'd check that first... quoted below. #PIP3089B: SES Light And Reduced Engine Power DTC P0120 P0220 P1516 P2135 - keywords accelerator actuator APP blade body connector connection DTC L33 L59 LH6 LR4 LM7 LS1 LS2 LQ4 LQ9 module position reduce sensor - (Oct 31, 2006) Subject: SES Light and Reduced Engine Power DTC P0120 P0220 P1516 P2135 Models: 2004-2006 Buick Rainer 2005-2006 Cadillac CTS-V 2003-2006 Cadillac Escalade 2003-2006 Chevrolet Avalanche, Corvette, Express, Monte Carlo, Silverado, SSR, Suburban, Tahoe, Trailblazer 2003-2006 GMC Envoy, Savana, Sierra, Yukon 2003-2006 Hummer H2 2005-2006 Pontiac GTO Equipped with a 4.8 5.3 6.0 or 7.0 V-8 EngineThe following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI. Condition/Concern:A vehicle may be brought into the dealer for a reduced power message, and DTCs P0120, P0220, P1516, P2101, or P2135. The Throttle Actuator Control (TAC) / throttle body type trouble codes, may be caused by a loose wiring crimp at the throttle body connector, or a broken throttle body circuit. Recommendation/Instructions:Complete the current SI diagnostics for any symptoms or trouble codes found. If a intermittent T/P or TAC module type code is occurring complete the inspections below. Inspect all related throttle body terminals for a loose wiring crimp. The loose crimp may be difficult to find, and the poor connection will be between the terminal and the copper strands of the wire. Wiggle test the individual throttle body circuits to see if the concern can be duplicated. Inspect the related circuits for broken wires inside the insulation. The outer wire insulation may look fine, but the internal copper strands may be partially broken. Breaks in the wires usually occur within 1 to 4 inches of the throttle body connector. Wiggle testing may also induce a trouble code to set. On C/K trucks complete SI procedures for voltage drop on grounds G103 and G104. Grounds G103 or G104 may be loose or corroded. If a terminal crimp or a broken wire has been found, repair or replace only the circuits involved. There is a throttle body pigtail connector available through GMSPO, but installing this pigtail connector may cause other intermittent TAC module/TP codes at a later date. If this pigtail must be used, please follow the SI procedures for Splicing Copper Wire Using Splice Sleeves. (the proper Kent-Moore crimping tool must be used for this repair) Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

Prolong Posted July 3, 2013 Author Report Share Posted July 3, 2013 there is a GM bulliten on those codes, i'd check that first... quoted below. I've already done this and that pigtail is already switched I had a new one on there from awhile back. Quote Link to comment Share on other sites More sharing options...
Sik-rod-yo Posted July 27, 2013 Report Share Posted July 27, 2013 I would just replace the whole harness Quote Link to comment Share on other sites More sharing options...
