Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
DTC P061F: Electronic Throttle Control System (ETCS) Malfunction: General Description
The electronic throttle control system (ETCS) opens and closes the throttle valve electronically. This system consists of the throttle actuator, the throttle valve, throttle position (TP) sensors A/B, accelerator pedal position (APP) sensors A/B, and the powertrain control module (PCM).
When the driver operates the acceleration pedal, the accelerator pedal position (APP) sensor indicates the actual pedal position. The acceleration pedal stepping amount is converted to a signal at the APP sensor, and the throttle valve opening degree target value is based on this amount. The throttle actuator is driven to be this target value, and the APP value must agree. The actual throttle valve opening is detected by TP sensor A, attached to the throttle body.
The throttle actuator controller makes a self-diagnosis of the ROM, RAM, and A/D converter, and when the internal data is abnormal, a malfunction is detected in the throttle actuator controller and a DTC is stored.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
