Throttle Sensor (Method With SUBARU Select Monitor)

NOTE:

Individual difference of the accelerator pedal may not be corrected sufficiently on the ECM side after DTCs were cleared or the battery was removed and installed on the vehicle. Therefore, using the Subaru Select Monitor, check that the accelerator opening angle signal indicates 100%, when the accelerator pedal is fully depressed, and then perform the inspection.
If the accelerator opening angle signal does not indicate 100%, check the accelerator pedal. Ref. to SPEED CONTROL SYSTEMS (H4DOTC)>Accelerator Pedal>INSPECTION .

Turn the ignition switch to ON. (Engine OFF)

While reading the accelerator opening angle signal and throttle sensor voltage using Subaru Select Monitor, depress the accelerator pedal to fully open and fully closed. Ref. to ENGINE (DIAGNOSTICS) (H4DOTC)>DATA MONITOR .

NOTE: Due to the specification of the Subaru Select Monitor, value read from the accelerator opening angle signal is highlighted and displayed as the voltage readings of sub throttle sensor.
