NOTE:
For circuit identification, see WIRING DIAGRAMS article. After each repair procedure has been completed, reconnect all components. Perform TEST VER-5 to ensure system is functioning properly. Ensure no DTCs are present before performing this test.
- Start engine and allow it to idle. Using scan tool, monitor engine speed (RPM) while wiggling Throttle Position (TP) sensor connector and wiring harness. If RPM changes while wiggling connector and wiring harness, repair connector and wiring harness where wiggling caused RPM to change. If RPM does not change while wiggling connector and wiring harness, turn ignition off and go to next step.
- Turn ignition on. Using scan tool, monitor TP sensor voltage while slowly opening throttle to Wide Open Throttle (WOT), then close throttle. If voltage change was smooth, go to next step. If voltage change was not smooth, replace TP sensor.
- Ensure ignition is on. Using scan tool, monitor TP sensor voltage while wiggling TP sensor connector and wiring harness. If voltage changes while wiggling connector and wiring harness, repair connector and wiring harness where wiggling caused voltage to change. If voltage does not change while wiggling connector and wiring harness, go to next step.
- Turn ignition off. Visually inspect related connectors and wiring harness for damage. Repair connectors and wiring harness as necessary. If connectors and wiring harness are okay, reconnect all connectors. No problem is indicated at this time. Test is complete.
- Turn ignition on. Using scan tool, read TP sensor voltage. Ensure throttle is closed against throttle stop. If voltage is .92 volt or less, no problem is indicated at this time. Test is complete. If voltage is more than .92 volt, check for binding throttle. Repair throttle linkage as necessary. If throttle is not binding, replace TP sensor.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
