What is voltage of accelerator pedal position sensor?
Turn the ignition off, disconnect the accelerator pedal position sensor harness connector. Turn the ignition on, measure the voltage between ground and the 5 volt supply circuit in the accelerator pedal position sensor harness connector. Is the voltage between 4.9 and 5.2 volts? Yes, go to step 3.
What is the code for electronic throttle control?
P2122, P2127 code – The Electronic Throttle Control (ETC) system uses two Accelerator Pedal Position (APP) Sensors to monitor the accelerator pedal position. The APP sensors 1 and 2 are integrated into one assembly located at the pedal assembly.
What are the sensors in the ETC system?
P2122, P2127 code – The Electronic Throttle Control (ETC) system uses two Accelerator Pedal Position (APP) Sensors to monitor the accelerator pedal position.
What should the app sensor 1 voltage be?
When operating properly, the voltage reading of the sensor operating on the 2.5 volt scale will always be appropximately half of the voltage reading of the sensor on the 5.0 volt scale. Set condition this DTC the Powertrain Control Module (PCM) detects that the APP sensor 1 input voltage is below the minimum acceptable value.
How to repair a wiring harness and throttle position sensor?
Plug in the wiring harness connector if you are not going to change it. Cut the wires on the pigtail about 1 inch away from where they enter the main wiring harness. Strip about 1/2 inch of the insulation off the wires at the main wiring harness connector. Insert each one of the bare wires into a separate butt connector.
How to check the accelerator pedal position sensor 1 circuit?
Check the APP sensor ground 1 circuit for an open or high resistance Measure the resistance of the APP sensor ground 1 circuit between the Accelerator pedal position sensor harness connector and the PCM harness connector. Is the resistance below 3.0 Ohms? Yes, go to step 7.
How does the Accelerator Position Sensor ( APS ) work?
The Accelerator Position Sensor (APS) is a potentiometer sensor. When the APS receives a 5V reference signal and a ground from the Electronic Control Module (ECM), a linear analog voltage signal will indicate a demand for power.
P2122, P2127 code – The Electronic Throttle Control (ETC) system uses two Accelerator Pedal Position (APP) Sensors to monitor the accelerator pedal position.
