PNP Switch, Stop Lamp Switch and Throttle
Position Switch
NLAT0290SYMPTOM:
SPORT indicator lamp does not come on in TCM self-diagnos-
tic procedure even the lamp circuit is good.
DESCRIPTIONNLAT0290S01+PNP switch
+The PNP switch assemble includes a transmission position
switch. The transmission position switch detects the selector
position and sends a signal to the TCM.
+Stop lamp switch
Detects the stop lamp switch position (ON or OFF) 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 ProcedureNLAT0291

With CONSULT-II
1. Turn ignition switch to ªONº position.
(Do not start engine.)
2. Select ªTCM INPUT SIGNALSº in ªDATA MONITORº mode for ªCVTº with CONSULT-II.
