Possible causes

– Faulty Throttle Actuator Control (TAC) module
– Throttle Actuator Control (TAC) module harness is open or shorted
– Throttle Actuator Control (TAC) module circuit poor electrical connection (loose or broken wires)

When is the code detected?

The U0107 code is set when the Powertrain Control Module (PCM) detects a loss of data or invalid data from the Throttle Actuator Control (TAC)

Symptoms

– Engine Light ON (or Service Engine Soon Warning Light)
– No throttle response

U0107 BUICK Description

The Throttle Actuator Control (TAC) module and the Powertrain Control Module (PCM) communicate via a dedicated serial data circuit. This serial data circuit is separated from nau other serial data circuit on the vehicle. Accurate transmitting and reveicing of serial data requires no only agood cricuit integrity, but also adequate system voltage. This diagnostic test monitors de accuaracy od the serial data trasmitted between the TAC module and the PCM.
