Car drives slow and won't eccelerate
Hello!
The computer turns this light on when there is a powertrain malfunction/electronic throttle body system malfunction. It could be the throttle body, computer, wiring or a sensor into the computer used for the throttle body. You will need to scan your computer again when the code is illuminated on the dash. Chances are you will pick up a code when this is done in the computer.
Accelerator Pedal Position (APP) Sensor
The APP sensor is an input to the powertrain control module (PCM) and is used to determine the torque demand. There are 3 pedal position signals in the sensor. Signal 1, APPS1, has a negative slope (increasing angle, decreasing voltage) and signals 2 and 3, APPS2 and APPS3, both have a positive slope (increasing angle, increasing voltage). During normal operation APPS1 is used as the indication of pedal position by the strategy. The 3 pedal position signals make sure the PCM receives a correct input even if 1 signal has a concern. There are 2 reference voltage circuits and 2 signal return circuits for the sensor. For additional information, refer to Torque Based Electronic Throttle Control (ETC) in this section.
It should be noted that the ETC system includes a warning indicator, wrench warning indicator, on the instrument cluster that illuminates when a concern is present. Concerns are accompanied by diagnostic trouble codes (DTCs) and may also illuminate the malfunction indicator lamp (MIL).
You best bet is to take your vehicle to a ASE certified repair shop or the Ford dealer !
