Throttle Position Sensor

NOTE: For circuit identification and wiring diagram, see WIRING DIAGRAMS article. After each repair procedure has been completed, reconnect all components. Perform POWERTRAIN VERIFICATION TEST VER-2  under VERIFICATION TESTS to ensure system is functioning properly.
NOTE: Before proceeding, ensure throttle plate and linkage are operating properly and are free from binding.
  1. Turn ignition on. Using scan tool, read TP sensor voltage. If voltage is 1.5 volts or less, go to next step. If voltage is 1.5 volts or more, replace TP sensor.
  2. While monitoring TP sensor voltage on scan tool, slowly open and close throttle. Voltage should be about .8 volt at idle, and increase smoothly to more than 3.5 volts at wide open throttle. If voltage is not as specified, replace TP sensor. If voltage is as specified, TP sensor is operating normally. Test is complete.
