How do I fix code U0107?
How to diagnose and repair U0107
- Perform a preliminary inspection. Sometimes U0107 can pop up intermittently, or it can result from a dead battery.
- Check the battery. Like any other module, the TAC needs proper battery voltage to operate.
- Check for other DTCs.
- Check for a faulty control module.
What causes a P1516 code?
Definition. The PCM (powertrain control module, also known as ECM or engine control module) works as the control center of the TAC (Throttle Actuator Control) system. Error Code P1516 is detected when the PCM has determined an out of range condition between the predicted and the actual position of the throttle.
What does a TAC module do?
The Throttle Actuator Control (TAC) Module is the brain behind the Electronic Throttle Control System in the GM 4.8L, 5.3L, and 6.0L engines covered by this article. The PCM determines the intention of the driver, and will then calculate the appropriate response on the throttle.
What is a 411 ECM?
411 and the 4896 are interchangeable computers. 411 is the service part # for the earlier (99-00) computer. There is no need to buy anything additional over what you have. They can run the same OS, same tuning parameters. Just get it wired up and your buddy can plug in to the OBD2 port and away you go.
What are the symptoms of an u0107 engine code?
Symptoms of a U0107 engine code may include: Electronic Throttle Control Indicator On or Flashing No throttle response – engine will only idle Typically the causes for this code to set are:
When does DTC u0107 set when battery voltage is low?
•DTC U0107 sets if the battery voltage is low. If the customer’s concern is slow cranking or no crank because battery voltage is low, ignore DTC U0107. Clear any DTCs from memory that may have set from the low battery voltage condition. •DTC U0107 sets when there is a short to B+ on the TAC module ground circuit.
When does DTC u0107 set Chevy Silverado?
•DTC U0107 sets when there is a short to B+ on the TAC module ground circuit. Inspect the fuses for the circuits that are in the TAC module harness-i.e. cruise, brake. An inspection of the fuses may lead you to the circuit that is shorted to the TAC module ground circuit.
Why is my gpcm not communicating with u0107?
If you can access codes from the TAC module, then the U0107 code is either intermittent or a memory code. If unable to communicate with the GPCM module, then the U0107 code that the other modules are setting is active, and the problem is there now. The most common failure is loss of power or ground.
