P2107 Throttle Actuator Control Module Processor

OBD-II DTC Datasheet

Throttle actuator control module processor

What does this mean?

This Generic Transmission Diagnostic Trouble Code (DTC) generally applies to all OBD-II equipped vehicles that use a wired throttle control system, including but not limited to Ford, Mazda, Lincoln, Dodge, Mercedes-Benz, Cadillac vehicles, Jeep, etc. Ironically, this code seems to be the most common on Ford models, second only to Lincoln and Mazda.

The P2107 OBD-II DTC is one of the possible codes that indicates that the powertrain control module (PCM) has detected a malfunction in the throttle actuator control system.

There are six codes related to throttle actuator control system malfunctions and they are P2107, P2108, P2111, P2112, P2118 and P2119. P2107 is set by the PCM when the TPMS processor has a general fault.

The PCM controls the throttle actuator control system by monitoring one or more throttle position sensors. Throttle body operation is determined by the position of the throttle body, which is controlled by one or more throttle actuator control motors. The PCM also monitors the accelerator pedal position sensor to determine how fast the driver wants to drive, and then determines the appropriate throttle response. The PCM accomplishes this by changing the flow of current to the throttle actuator control motor, which moves the throttle valve to the desired position. Some faults will cause the PCM to restrict the operation of the throttle actuator control system. This is called fail-safe or non-stop mode in which the engine idles or may not start at all.

Code severity and symptoms

The severity of this code can be medium to severe depending on the specific problem. Symptoms of a P2107 DTC may include:

• The engine will not start
• Poor performance that progresses
• Little or no throttle response
• Check Engine light is on
• Exhaust smoke
• Increased fuel consumption

Common Causes of the P2107 Code

Possible reasons for this code could include:

• Defective throttle body
• Dirty throttle or lever
• Defective throttle position sensor
• Defective accelerator pedal position sensor
• Throttle actuator motor defective
• Corroded or damaged connector
• Faulty or damaged wiring
• Defective PCM

Normal repair

• Replacing the throttle body
• Cleaning the throttle body and linkage
• Throttle Position Sensor Replacement
• Replacing the throttle actuator control motor
• Replacing the accelerator pedal position sensor
• Cleaning connectors from corrosion
• Repair or replacement of wiring
• Flashing or replacing PCM

Diagnostic and repair procedures

Check for TSB availability

The first step in troubleshooting any problem is to review the vehicle-specific Technical Service Bulletins (TSBs) by year, model, and powerplant. In some cases, this can save you a lot of time in the long run by pointing you in the right direction. This is especially important if you own a Ford as we are aware of a number of known issues with both Ford and Lincoln models.

The second step is to find all the components related to the throttle actuator control system. This will include the throttle body, throttle position sensor, throttle actuator control motor, PCM and accelerator position sensor in a simplex system. Once these components are located, a thorough visual inspection must be performed to check all associated wiring for obvious defects such as scratches, abrasions, exposed wires, burn marks, or melted plastic. The connectors of each component must then be checked for security, corrosion, and pin damage.

The final visual and physical inspection is the throttle body. With the ignition off, you can turn the throttle by pushing it down. It should rotate to a wide open position. If there is sediment behind the plate, it should be cleaned while it is available.

Advanced steps

The additional steps become very vehicle specific and require appropriate advanced equipment to be performed accurately. These procedures require a digital multimeter and vehicle-specific technical reference documents. Voltage requirements depend on the specific year of manufacture, vehicle model and engine.

Checking circuits

Ignition OFF, disconnect the electrical connector at the throttle body. Locate the 2 motor or motors pins on the throttle body. Using a digital ohmmeter set to ohms, check the resistance of the motor or motors. The motor should read approximately 2 to 25 ohms depending on the specific vehicle (check your vehicle manufacturer's specifications). If the resistance is too high or too little, the throttle body must be replaced. If all tests have passed so far, you will want to check the voltage signals on the motor.

If this process detects that there is no power source or ground connection, a continuity test may be required to verify the integrity of the wiring. Continuity tests should always be performed with power disconnected from the circuit and normal readings should be 0 ohms of resistance unless otherwise specified in the technical data. Resistance or no continuity indicates a wiring problem that needs to be repaired or replaced.

Hopefully the information in this article has helped point you in the right direction for solving a problem with your throttle actuator control system. This article is for informational purposes only and specific technical data and service bulletins for your vehicle should always take priority.
