PRIMARY SPEED SENSOR
EXCEPT FOR EURO-OBD
Diagnostic Procedure
AT-136
SAT004K
Description
NLAT0257
+
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.
