3 CHECK INPUT SIGNAL (WITHOUT CONSULT-II)
Without CONSULT-II
1. Apply vacuum to the throttle opener then check the following. Refer to steps 1 to 5 of ªPreparationº, ªSELF-DIAGNOS-
TIC PROCEDURE (Without CONSULT-II)º, AT-44.
2. Turn ignition switch to ªONº position.
(Do not start engine.)
3. Check voltage between TCM terminals 41 and 42 while accelerator pedal is depressed slowly.
Voltage:
Fully-closed throttle valve:
Approximately 0.5V
Fully-open throttle valve:
Approximately 4V
(Voltage rises gradually in response to throttle position)
