Toyota Accelerator Pedal Position Sensor Wiring Diagram

It receives two reference voltages from the powertrain control module pcm having two ground wires and two signal wires that send a varying voltage back to the pcm relating to accelerator pedal position. The throttle position sensor detects. In many ways the app or accelerator position sensor is a dual tps connected to the gas pedal.

From efi main fuse from efi main relay throttle position sensor accelerator pedal position sensor etc. The ecm then adjusts the throttle angle based on the apps signals engine conditions and vehicle conditions. The throttle position sensor is a potentiometer built by cts i pulled out the corollas wiring diagram to see how the throttle position sensor is wired to the ecm.

The ecm is the big blue mass at the top. This accelerator pedal position sensor is a noncontact type. Stc wiring diagramcdr author. All conditions below are detected continuously for 8 sec.

Get the details on testing the app. In this example the accelerator pedal position app sensor is of the potentiometer type. It has 2 sensor terminals vpa and vpa2 to detect the accelerator pedal position and a malfunction of the accelerator pedal position sensor itself. Toyota recall a look inside the gas pedal and all its parts a youtube first duration.

Accelerator pedal position sensor video demonstrating. The accelerator pedal position sensor is mounted on the accelerator pedal to detect how much it is de pressed. Allan warburton created date. Or more a vehicle speed signal 0 km h 0 mph b engine speed 1800 3200 rpm c engine coolant temp.

There are variations on testing the app as opposed to a simple tps. What follows is my speculation as to how it functions. 10282014 103508 am. If there are any trained toyota mechanics that can correct my speculation please chime in.

As the driver moves the accelerator pedal the apps signal voltage changes indicating a new pedal position. The accelerator pedal position sensor is mounted at the accelerator pedal. I was questioning what would happen if one of the wires between the ecm and the throttle position sensor became disconnected. The throttle position sensor is t1 the light blue rectangle in the lower right.
