P069F Throttle Actuator Control Lamp Control Circuit
OBD-II Trouble Code Technical Description
Throttle Actuator Control Lamp Control Circuit
What does that mean?
This is a generic diagnostic trouble code (DTC) and applies to many OBD-II vehicles (1996-newer). That may include but is not limited to vehicles from Chevrolet, Chrysler, Dodge, Ford, GMC, Hyundai, Kia, Honda, Toyota, etc. Although generic, the exact repair steps may vary depending on year, make, model and powertrain configuration.
A stored code P069F means that the powertrain control module (PCM) has detected a malfunction in the throttle actuator control lamp control circuit.
The throttle actuator control lamp is an integrated part of the instrument panel. Its primary function is to alert the driver that the throttle actuator control system has exhibited a malfunction (when it is illuminated). The throttle actuator control system is responsible for opening and closing the throttle plate in order to increase/decrease engine RPM as demanded.
The PCM typically monitors the continuity of the throttle actuator control lamp control circuit whenever the ignition is turned on. The throttle actuator control system uses input signals from the vehicle throttle position sensor (TPS) to actuate the throttle plate and regulate the appropriate degree of ambient air entering the engine. The PCM supplies electronic servo motors with the required voltage signal to open or close the throttle plate as demanded.
Each time the ignition is turned on and the PCM is energized, multiple controller self-tests are performed. In addition to running internal controller self-tests, the controller area network (CAN) carries serial data from each individual module to ensure that on-board controllers are interfacing properly.
If a problem is detected in monitoring the throttle actuator control lamp control circuit, a code P069F will be stored and a malfunction indicator lamp (MIL) may be illuminated.
What is the severity of this DTC?
A stored code P069F (with throttle actuator control lamp illumination) will likely be accompanied by a loss of throttle control. This code should be considered severe and diagnosed as soon as possible.
What are some of the symptoms of the code?
Symptoms of a P069F trouble code may include:
Throttle actuator control system inoperative Throttle actuator control lamp inoperative Throttle actuator control lamp illuminated Other stored throttle system codesWhat are some of the common causes of the code?
Causes for this code may include:
Faulty PCM PCM programming error Open or shorted throttle actuator control lamp control circuit Defective throttle actuator control lamp bulbWhat are some P069F troubleshooting steps?
A diagnostic scanner, a digital volt/ohmmeter (DVOM), and a source of reliable vehicle information will be required to diagnose a code P069F.
Consult your vehicle information source for technical service bulletins (TSB) that replicate the code stored, vehicle (year, make, model, and engine), and symptoms exhibited. If you find the appropriate TSB, it may yield helpful diagnostic information.
Begin by connecting the scanner to the vehicle diagnostic port and retrieving all stored codes and freeze frame data. You will want to write this information down, just in case the code proves to be an intermittent one. After recording all pertinent information, clear the codes and test drive the vehicle until the code is reset or the PCM enters readiness mode.
If the PCM enters readiness mode, the code is intermittent and will be more difficult to diagnose. The condition, which caused the P069F to be stored, may need to worsen before an accurate diagnosis can be reached. If the code is reset, continue with your diagnosis.
