Fault Code P061F – Internal Performance Error of the Throttle Actuator Controller
DTC P061F: Generic OBD-II code related to the powertrain
What is the P061F Code?
Diagnostic code P061F indicates an internal error in the Powertrain Control Module (PCM), detected at the throttle actuator controller. It is common on vehicles equipped with a Drive-by-Wire (DBW) system, particularly Ford models (Mustang, F-150…).
Operation of the DBW System
The DBW system replaces the cable accelerator with an electric motor controlled by the PCM. It uses:
- Accelerator Pedal Position (APP) sensors
- Throttle Position (TPS) sensors
The PCM adjusts the throttle position based on signals from these sensors to precisely control acceleration.
Detection of Code P061F
When the ignition is turned on, the PCM performs self-tests. If an inconsistency is detected between TPS/APP signals or between modules, code P061F is stored and may trigger the Malfunction Indicator Lamp (MIL) and switch to limp mode.
Severity of the Code
Code P061F is serious. It can cause:
- Limited or no acceleration
- Stuck throttle
- Irregular idle
- Reduced performance
- Increased fuel consumption
Possible Causes of Code P061F
- Faulty DBW actuator motor
- Failed TPS or APP sensor
- PCM programming error
- Damaged or shorted wiring harness
- Module ground issue
- Faulty PCM
Recommended Diagnostic Steps
- Scan the vehicle to read codes and freeze frame data
- Clear codes, then test again to see if the code returns
- Check Technical Service Bulletins (TSBs) related to your model
- Test APP and TPS sensors with a multimeter (DVOM)
- Check PCM power supplies and grounds
- Inspect wiring, connectors, relays, and fuses
- Test the throttle actuator motor
- Replace or reprogram the PCM if necessary (by a professional)
⚠️ Warning: Reprogramming requires specific equipment. In some cases, the PCM must be replaced with a pre-programmed unit.
