Throttle Position Sensor (TPS)

Faults in TPS circuit may set Code 43. To test system, see CODE 43 diagnostic procedures in appropriate G - TESTS W/ CODES article in the ENGINE PERFORMANCE section below.

  1. To test TPS, disconnect TPS connector. TPS is mounted on side of throttle body. While opening and closing throttle, check resistance across specified wire terminals of TPS connector. See THROTTLE POSITION SENSOR RESISTANCE TEST table. If resistance value does not change smoothly, replace TPS.
  2. If resistance is not as specified, check harness. If harness is okay, adjust TPS. See ADJUSTMENTS article in the ENGINE PERFORMANCE section. If resistance is still not as specified after adjustment, replace TPS.
