Fault code P060D – internal control module accelerator pedal position performance

Fault code P060D is called “Internal Control Module Accelerator Pedal Position Performance” but in different programs it may be called differently. This fault designation applies to all vehicles equipped with OBD-II.

Technical description and explained code P060D

Stored code P060D means that the powertrain control module (PCM) has detected an internal performance error with the accelerator pedal position. Other controllers may also detect a PCM processor performance error and cause this code to be stored.

Fault code P060D – internal control module accelerator pedal position performance

The module’s internal monitoring is responsible for various controller self-test functions and overall accountability. Accelerator pedal position inputs and outputs are self-tested and constantly monitored by the PCM.

In most vehicles, the DBW system is used instead of a cable-operated throttle. Not only does this help improve fuel economy, but it also facilitates better interaction with the stability and traction control systems. It also helps optimize the accuracy of the cruise control systems.

Controlled by the PCM via an electric throttle motor, the DBW uses one or more accelerator pedal position sensors (APP). It also uses several throttle position sensors (TPS). All of these sensors have a 5 volt reference voltage and a ground signal.

The APP/TPS sensor inputs allow the PCM to control the actual throttle position with the throttle actuator motor. The PCM makes the necessary adjustments by moving the throttle actuator motor in the appropriate direction.

When the ignition is turned on and power is applied to the PCM, a self-test of the throttle actuator controller is initiated. In addition to performing the self-test, the Controller Area Network (CAN) also compares signals from each individual module. To ensure that each controller is operating properly, these tests are performed simultaneously.

If the TPS/APP sensor inputs exceed the maximum deviation set by the manufacturer, code P060D will be stored in memory. In addition, if the PCM detects a mismatch between any of the on-board controllers. Which indicates an internal APP or TPS sensor signal error, this code will also be stored.

It may take several failure cycles for the MIL check lamp to turn on, depending on the perceived severity of the fault.

Symptoms of vehicle malfunctions

The main signal that an error P060D has occurred is the Malfunction Indicator Lamp (MIL) is also known as the CheckEngine Light.

It can also be warning signs such as:

  1. The “Check engine” control lamp on the control panel will light up (the code will be written in the memory as a malfunction).
  2. The engine cannot be accelerated, the throttle response is unresponsive.
  3. Stuck throttle valve.
  4. Floating revolutions, and attempts to stall at idle.
  5. Controllability problems.
  6. Increased fuel consumption.

Failure of the module processor in the internal control should be categorized as a serious code. A stored error P060D can suddenly and without warning lead to serious steering problems.

Factors that can cause this error code

The error code P060D can mean that one or more of the following problems have occurred:

  • DBW drive motor is defective.
  • Open or short circuit in wiring circuit.
  • Corroded electrical sensor connector.
  • CAN bus may be faulty and shorted to ground or wire breakage.
  • Defective TPS or APP sensor.
  • Insufficient grounding of the control module.
  • Sometimes the cause is the PCM itself.

How to fix or reset OBD-2 code P060D

Some suggested steps for troubleshooting and fix the error code P060D:

  1. Read all stored data and error codes with an OBD-II scan tool. To find out when and under what circumstances error P060D appears.
  2. Clear the error codes from the computer memory, and test-drive the vehicle to find out if the malfunction appears again.
  3. Check the DBW drive motor and the circuits and connectors.
  4. If the error code appears again, visually inspect the control module (PCM) electrical wiring and connector.
  5. Check the TPS or APP sensors.
  6. Measure battery voltage and compare with manufacturer’s specification.
  7. Check the continuity of the power and ground circuits of the Control Module (PCM) with a multimeter.
  8. Evaluate the Control Module (PCM) operation following the vehicle manufacturer’s procedure.
  9. Clear the error code from the computer memory again, and test drive the vehicle to determine if the problem has been resolved.

Diagnose and repair of problems

If ECM/PCM power supply codes are present, they must be cleared before attempting to diagnose error P060D. Also, if TPS / APP sensor codes are present, they must be cleared first.

Next, you must connect the scan tool to the vehicle’s diagnostic port and retrieve all stored codes and data. Make a note of this information in case the code turns out to be intermittent.

After recording all the necessary information, clear the codes and test drive the vehicle until the code is cleared or the PCM goes into standby mode. If the PCM goes into standby mode, the code is intermittent and will be more difficult to diagnose.

Check the controller and electrical parts

Use a multimeter to check the fuses and power relays on the controller. Check and replace blown fuses if necessary. Fuses should be checked with the circuit loaded.

If all fuses and relays are working as they should, a visual inspection of the controller wiring and harnesses should be performed. Chassis and motor grounding should also be checked.

Visually inspect the system controllers for signs of water, temperature, or collision damage. Any controller that is damaged, especially by water, should be considered faulty.

If the power and ground circuits of the controller are intact, it is likely that the controller itself is defective or that a programming error exists. Reprogramming the control module will be necessary to replace it.

Unlike most other codes, error P060D is most likely caused by a faulty controller or its programming error.

Some aftermarket PCM manufacturers offer preprogrammed controllers for certain models. Contact your auto parts supplier with the vehicle serial number, mileage, and other pertinent information.

On which vehicles does this problem occur most frequently

Fault code P060D can occur on different vehicles but there are statistics on which brands this occurs most often. Here is a list of some of them:

  • Chevrolet
  • Daewoo (Gentra)
  • Ford (Fiesta, Focus, Kuga)
  • GMC
  • Isuzu (NPR75)
