DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION
PROCEDURE
NJAT0307S03CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If ªDIAGNOSTIC TROUBLE CODE CONFIRMATION PROCE-
DUREº has been previously conducted, always turn ignition
switch ªOFFº and wait at least 5 seconds before conducting
the next test.
After the repair, perform the following procedure to confirm the
malfunction is eliminated.
With CONSULT-II
1) Turn ignition switch ªONº and select ªDATA MONITORº mode
for ªENGINEº with CONSULT-II.
2) Start engine.
3) Drive vehicle in D position and allow the transmission to shift
1®2®3 (ªGEARº).
With GST
Follow the procedure ªWith CONSULT-IIº.

DescriptionNJAT0311+Throttle position sensor
The throttle position sensor detects the throttle valve position
and sends a signal to the TCM.
+Throttle position switch
Consists of a wide open throttle position switch and a closed
throttle position switch.
The wide open throttle position switch sends a signal to the
TCM when the throttle valve is open at least 1/2 of the full
throttle position. The closed throttle position switch sends a
signal to the TCM when the throttle valve is fully closed.
