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.

DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION
PROCEDURE
NJAT0311S04CAUTION:
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.

AT-260.
If the check result is OK, go to following step.
4) Turn ignition switch ªONº and select ªDATA MONITORº mode
for ªENGINEº with CONSULT-II.
5) Start engine and maintain the following conditions for at least
3 consecutive seconds. Then release accelerator pedal com-
pletely.
VHCL SPEED SE: 10 km/h (6 MPH) or more
THRTL POS SEN: Approximately 3V or less
Selector lever: D position (OD ªONº)
If the check result is NG, go to ªDIAGNOSTIC PROCEDUREº,
AT-260.
If the check result is OK, go to following step.
6) Maintain the following conditions for at least 3 consecutive
seconds. Then release accelerator pedal completely.
