Circuit Diagram Of The Throttle Position Sensor (TPS)

Circuit Diagram Of The Throttle Position Sensor (TPS). How To Test The Throttle Position Sensor (1998, 1999, 2000 3.0L Dodge/Plymouth Mini-Van)

NOTE: The illustration of the TPS circuit diagram applies only to the following Dodge Plymouth minivans:

  • 1998, 1999, 2000 3.0L Dodge Caravan.
  • 1998, 1999, 2000 3.0L Grand Caravan.
  • 1998, 1999, 2000 3.0L Plymouth Voyager.
  • 1998, 1999, 2000 3.0L Plymouth Grand Voyager.

TPS PIN #1: Ground input to the TPS. This wire is a black with light blue stripe (BLK/LT BLU) color. It connects directly to PCM connector terminal number 43.

The BLK/LT BLU wire also feeds Ground to the following sensors:

  • CMP -Camshaft Position Sensor.
  • CKP -Crankshaft Position Sensor.
  • O2S1 -Front Oxygen Sensor (before catalytic converter).
  • O2S2 -Rear Oxygen Sensor (after catalytic converter).
  • ECT -Engine Coolant Temperature Sensor.
  • MAP -Manifold Absolute Pressure Sensor.
  • AC PRESSURE TRANSDUCER -AC High Pressure Switch.

TPS PIN #2: TP signal output to the PCM. This wire is a orange with dark blue stripe (ORG/DK BLU) wire. It connects directly to the Powertrain Control Module (PCM) connector terminal number 35.

TPS PIN #3: 5 Volts DC input to the throttle position sensor (TPS). This wire is a violet with white stripe (VIO/WHT) color. It connects directly to the Powertrain Control Module (PCM) connector terminal number 61.

The VIO/WHT wire also feeds 5 Volts to the following sensors:

  • MAP sensor.
  • AC Pressure Transducer.
