Wiring diagram for code u0107 2004 avalanche


Do you even know what DTC U0107 involves ?
DTC U0107
Lost Communications With Throttle Actuator Control (TAC) Module

The throttle actuator control (TAC) module and the powertrain control module (PCM) communicate via a dedicated serial data circuit. This serial data circuit is separate from any other serial data circuit on the vehicle. Accurate transmitting and receiving of serial data requires not only good circuit integrity, but also adequate system voltage. This diagnostic test monitors the accuracy of the serial data transmitted between the TAC module and the PCM. If the PCM detects a loss of data or invalid data, this DTC sets.

Diagnostic Aids
Important: Reprogramming the PCM may cause a communication error between the PCM and the TAC. If the PCM detects a communication error, DTC U0107 sets. Clear any DTCs from the memory that may have been set by Reprogramming.
• 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. 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.
Replace the TAC module. Refer to Electronic Throttle Actuator Control Module Replacement .
Did you complete the replacement?

Start and dies, codes p061f, p2106,p2104,p2111


code p2106 refers to throttle actuator control (TAC) system--limited power mode===causes ---wiring---TAC motor---APP sensor---ECM

code o2104 refers to TAQC systems ---forced idle mode===causes wiring---TAC motor--APP sensor--ECM

code p2111 refers to TAC system --actuator stuck open ==causes ---throttle body--throttle valve tight/ sticking

code p2111 also refers to TAC system --circuit malfunction==causes wiring---short to positive--short to ground---TP sensor---ECM

code p2111 also has a 3rd section---brake vacuum---implausible signal===causes---wiring---vacuum sensor--mechanical fault

Engine won't start and shows trouble code P1516 and reduced engine power light is on


Here is the definition of the code.

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)

P1516 CHEVROLET Description The Throttle Actuator Control (TAC) module contains data which is essential for proper TAC operation. The TAC module continuously test the integrity of this data. When the TAC module is unable to write or read data to and from Random Access Memory (RAM), or the TAC module is unable to correctly read data from the flash memory or and internal TAC module processor fault is detected and the Detected Trouble Code (DTC) is set.

No throttle response


What you replaced is the APP(accelerator pedal position) It is part of the electronic throttle control,what was truly needed is know as the TAC MOTOR. This recieves signal from the APP.The TAC is what accelerate the car.The only thing you can do other than replace the TAC,is do a TAC relearn .Turn thhe key off. wait ten seconds,Turn key on with the engine off.leave 1 minute. Turn key off start the vehicle you will hear the TAC motor setting itself.

2009 Ford Fusion codes 2107,2110 car slows to 30mph and will no longer accelerate


Well, those codes definately are related to why your vehicle will no longer accelerate!

P2107 is "Throttle Actuator Control (TAC) Module Processor"
This code means that the TAC portion of the Powertrain Control Module (PCM) has failed the self-test.

Posiible causes:
> TAC motor circuit harness shorted to ground
> TAC motor circuit harness shorted to voltage
> Damage Electronic Throttle Body (ETB)
> Damaged PCM

P2110 is "Throttle Actuator Control (TAC) Forced Limited RPM"

This code is informational only. It sets in conjunction with other throttle actuator control codes (like P2107 above). It is just letting you know that the PCM is limiting RPM due to a TAC malfunction, (So it doesn't do a "TOYOTA" on you and run away!"

Waht ist tha p1516


DTC P1516 - Throttle Actuator Control (TAC) Module Throttle Actuator Position Performance

zjlimited_667.jpg

Circuit Description (click over pic for zoom)
The commanded throttle position, based on accelerator pedal position and possibly other limiting factors, is compared to the Actual throttle position. The 2 values should be within a calibrated range of each other. Both the PCM and the TAC module redundantly monitor the Commanded and Actual throttle position. This DTC sets if the TAC module detects the problem.

Conditions for Setting the DTC
1. DTC P1518 is not set.
2. The ignition switch is in the crank or run position.
3. The ignition voltage is greater than 5.23 volts.
4. Not in battery saver mode.
5. The TAC module detects that the commanded and actual throttle positions are not within a calibrated range of each other or the PCM and the TAC cannot determine throttle position or both TP sensors are invalid.
6. All above conditions met for less than 1 second.

Action Taken When the DTC Sets
1. The PCM will illuminate the Malfunction Indicator Light (MIL) when this diagnostic runs and fails.
2. The Reduced Engine Power message displays on the drivers information center.
3. The PCM records the operating conditions at the time the diagnostic fails. The PCM stores this information in the Freeze Frame and/or Failure Records.
4. If no other TAC System DTCs are set, the TAC System will operate in Reduced Engine Power mode. If certain TAC System DTCs are set at the same time, the TAC System either defaults to a more tightly restricted mode of operation if the TAC determines that limited safe operation is possible, or the TAC commands the engine to shut down.

Conditions for Clearing the MIL/DTC
1. The PCM turns the MIL OFF after three consecutive drive trips that the diagnostic runs and does not fail.
2. A last test failed (Current DTC) will clear when the diagnostic runs and does not fail.
3. A History DTC clears after forty consecutive warm-up cycles, if this or any other emission related diagnostic does not report any failures.
4. The PCM battery voltage is interrupted.
5. Important
* The clear DTC info function may have to be performed twice in order to clear a Throttle Actuator Control System DTC.
* Clear the MIL/DTC information using a scan tool.

Diagnostic Aids
The following may cause an intermittent:
1. Poor connections. Check for adequate terminal tension. Refer to Troubleshooting Procedures, Checking Terminal Contact (Body and Accessories/Wiring Systems) for proper procedure.
2. Corrosion
3. Mis-routed harness
4. Rubbed through wire insulation
5. Broken wire inside the insulation
6. Inspect the TAC module connectors for signs of water intrusion. When this occurs, multiple DTCs should be set and no circuit or component problems can be located.

1. For an intermittent condition refer to Symptoms .
2. If a repair is completed and the DTC was cleared using a scan tool on the same ignition cycle, the default action will not clear until an ignition cycle has occurred.
3. When the TAC module detects a problem within the TAC System, more than one TAC System related DTC may set. This is due to the many redundant tests run continuously on this system. Locating and repairing one individual problem may correct more than one DTC. Keep this in mind when reviewing captured DTC info.

Test Description
The numbers below refer to the step numbers on the diagnostic table.

5. If the TP Indicated Angle does not follow the movement of the throttle blade, and no TP Sensor DTCs are set, there is a mechanical problem with the throttle shaft or the TP Sensor. Replace the throttle body assembly. Re-install the air inlet duct after you complete the repairs.

21. When a problem is detected within the TAC System, more than one TAC System related DTC may set. This is due to the many redundant tests run continuously on this system. It is possible that locating and repairing one individual problem may correct more than one DTC. Keep this in mind when reviewing captured DTC info.
