SEF505V
Component Description
NGEC0782
A closed throttle position switch and wide open throttle position
switch are built into the throttle position sensor unit. The wide open
throttle position switch is used only for A/T control.
When the throttle valve is in the closed position, the closed throttle
position switch sends a voltage signal to the ECM. The ECM only
uses this signal to open or close the EVAP canister purge volume
control solenoid valve when the throttle position sensor is malfunc-
tioning.
CONSULT-II Reference Value in Data Monitor
Mode
NGEC0783
Specification data are reference values.
MONITOR ITEM CONDITION SPECIFICATION
CLSD THL/P SW
쐌 Engine: After warming up, idle
the engine
Throttle valve: Idle position ON
Throttle valve: Slightly open OFF
ECM Terminals and Reference Value
NGEC0784
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM’s transistor. Use a ground other than the ECM terminals, such as the ground.

On Board Diagnosis Logic
NGEC0785
Malfunction is detected when battery voltage from the closed
throttle position switch is sent to ECM with the throttle valve
opened.
