Need help asap throttle code????

[1loehoe_tony]

I was being thrown a throttle body code so I changed it out relearned and even retuned it but it keeps throwing it into low engine power. Need help troubleshooting what it could be. I have a list of mods so if you think you can help me figure it out shoot a text in the thread.

It is typically the wiring or the wire connectors in that area. We're still dealing with a similar issue, but we haven't replaced the connectors, yet. If you search the forums, there are some other references to this as well.

Care to share the code?

Can you point me into the direction of those threads?

Do you have a capable scanner that can read out the freeze frame records?

Here is a look at the wiring. Scroll down to the Throttle system.

Two things come to mind: the wiring near the throttle body can be compromised internally; a careful inspection of the harness within about a foot of the TB might show a damaged wire. These typically break internally, under the wiring insulation, so inspection by feeling each wire by hand might show something.

Also inspect the connections at the TAC module, on the firewall near the brake booster.

@rockola1971 might have a suggestion or two.

Clear all codes. Start vehicle with hood already up. Wiggle connectors at TAC module and see if it goes into Reduced Engine Power. The wires break inside the insulation because the wiring just dangles off the plugs with zero mercy from gravity. If no luck there then check your ground braid at rear of engine block to firewall for loose/corroded/broken connection. The U0107 leads me to believe the problem is coming from the TAC module side and not the TPS side. If code immdiately pops after clearing without you doing anything then I would suspect TAC Module or Throttle POT at accelerator pedal assembly. You can check in real time with the right scanner the throttle position at the accelerator and it will be expressed as a percentage. Check for blanking out or large skips in percentage as you slowly "give it gas" (Engine off, key on).
