Test NTC-14: Checking Throttle Position (TP) Sensor

  1. Start engine and allow engine to idle. Using scan tool, monitor engine speed while wiggling wiring harness and connectors between TP sensor on throttle body and Powertrain Control Module (PCM). PCM is located at passenger's side front corner of engine compartment on inner fender panel. If no change exists in engine speed while wiggling wiring harness and connectors, go to next step. If engine speed changes while wiggling wiring harness and connectors, repair wiring or connector as necessary that caused engine speed to change. Perform TEST VER-5  .
  2. Shut engine off. Turn ignition on with engine off. Using scan tool, monitor TP sensor voltage while wiggling wiring harness and connectors between TP sensor and PCM. If TP sensor voltage does not change while wiggling wiring harness and connectors, go to next step. If TP sensor voltage changes while wiggling wiring harness and connectors, repair wiring or connector as necessary that caused TP sensor voltage to change. Perform TEST VER-5  .
  3. Turn ignition off. Inspect wiring harness and connectors between TP sensor and PCM for any damage or problems. If no problems exist, go to next step. If any problems exist, repair wiring or connectors as necessary. Perform TEST VER-5  .
  4. Turn ignition on with engine off. Ensure throttle is fully closed and against the stop. Using scan tool, read TP sensor voltage with throttle fully closed. If TP sensor voltage is 1.1 volts or less with throttle fully closed, go to next step. If TP sensor voltage is more than 1.1 volts with throttle fully closed, check for any binding condition in throttle. If binding condition exists, repair or replace components as necessary. Perform TEST VER-5  . If binding condition does not exist, replace TP sensor. Perform TEST VER-5  .
  5. Ensure ignition is on with engine off. Using scan tool, monitor TP sensor voltage while slowly moving throttle from closed position to fully open position. If TP sensor voltage changes smoothly, test is complete. If TP sensor voltage does not change smoothly, replace TP sensor. Perform TEST VER-5  .
