(7) From inside vehicle, install clip holding cable to dashpanel (Fig. 22). (8) From inside vehicle, slide throttle cable core wire into opening in top of pedal arm. (9) Push cable retainer (clip) into pedal arm open- ing until it snaps in place. (10) Snap cable into dashpanel routing clip. pedal to check for any binding. THROTTLE POSITION SENSOR DESCRIPTION The 3–wire Throttle Position Sensor (TPS) is mounted on the throttle body and is connected to the OPERATION The TPS is a 3–wire variable resistor that provides the Powertrain Control Module (PCM) with an input The PCM supplies approximately 5 volts to the TPS. The TPS output voltage (input signal to the The PCM needs to identify the actions and position of the throttle blade at all times. This information is • Ignition timing advance • Fuel injection pulse-width • Idle (learned value or minimum TPS) • Off-idle (0.06 volt) • Wide Open Throttle (WOT) open loop (2.608 volts above learned idle voltage) • Deceleration fuel lean out • Fuel cutoff during cranking at WOT (2.608 volts above learned idle voltage) • A/C WOT cutoff (certain automatic transmis- sions only) REMOVAL - 3.9L/5.2L/5.9L The TPS is located on side of throttle body. (4) Remove TPS from throttle body. REMOVAL - 4.7 The TPS is located on the throttle body.
