B3000 SE Cab Plus 4 4WD V6-3.0L OHV (2000)
Throttle Position Sensor: Description and Operation
-
Rotary potentiometer mounted on the throttle body that provides a signal to the PCM that is linearly proportional to the throttle plate/shaft
position.
-
The sensor housing has a three-blade electrical connector that may be gold plated. The gold plating increases corrosion resistance on terminals and
increases connector durability
-
As the TP sensor is rotated by the throttle shaft, four operating conditions are determined by the PCM from the TP:
-
Closed throttle (includes idle or deceleration)
-
Part throttle (includes cruise or moderate acceleration)
-
Wide open throttle (includes maximum acceleration or de-choke on crank)
-
Throttle angle rate.
