Nissan Primera P11. Instruction — part 27
PNP Switch, Stop Lamp Switch and Throttle
Position Switch
NAAT0204
SYMPTOM:
CVT or SPORT indicator lamp does not come on in TCM self-
diagnostic procedure even the lamp circuit is good.
DESCRIPTION
NAT0204S01
I
PNP switch
I
The PNP switch assemble includes a transmission range
switch. The transmission range switch detects the selector
position and sends a signal to the TCM.
I
Stop lamp switch
Detects the stop lamp switch position (ON or OFF) and sends
a signal to the TCM
I
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.
