ISSUE:
The following Throttle Position Sensor (TPS) TSB has been developed for service use. This TSB includes the following topics:
^
Description And Background Of TPS
^
(A1) and (A2) - Diagnostic Trouble Codes (Service Tips)
^
(B) Troubleshooting The TPS
^
(C) TPS Application Charts
ACTION:
If TPS diagnosis or repair is required, refer to the following procedures for service details.
Description
The Throttle Position Sensor (TPS) is a rotary potentiometer that provides a voltage signal to the Powertrain Control Module (PCM) that is linearly
proportional to the throttle plate/shaft angular position. The TP sensor has a three-blade electrical connector that is plated. The plating increases the
corrosion resistance on terminals and increases the connector durability. The TP sensor is mounted on the throttle body and is non-adjustable. As the TP
sensor is rotated by the throttle shaft, four (4) operating conditions are determined by the PCM from the TP sensor.
The four (4) vehicle operating conditions are:
^
Closed throttle (idle or deceleration)
^
Part throttle (cruise, moderate acceleration)
^
Wide open throttle (maximum acceleration, de-choke on crank and A/C shut-off)
^
Throttle angle rate.
Background
Recently, revisions have been made to the TPS, which have improved reliability and durability.
