Throttle/Pedal Position Sensor/Switch "D" Circuit Range/Performance
The throttle or accelerator pedal position sensor D is sending signals that are out of the expected range, meaning it's not working smoothly or consistently. This affects how well the engine responds to your inputs and can cause hesitation or jerky acceleration. The engine computer can't properly match throttle commands to engine speed.
