- Turn engine off. Turn ignition on. Using scan tool, read Throttle Position (TP) sensor voltage. Ensure throttle is fully closed and against throttle stop. If voltage is not 1.5 volts or less with throttle closed, replace TP sensor. Perform TEST VER-2.
- If voltage is 1.5 volts or less with throttle closed, monitor voltage while slowly opening throttle wide open. If voltage change is not smooth, replace TP sensor. Perform TEST VER-2. If voltage change is smooth, go to next step.
- If maximum voltage is not at least 3.4 volts at wide open throttle, replace TP sensor. Perform TEST VER-2. If maximum voltage is at least 3.4 volts at wide open throttle, TP sensor is functioning properly. Test is complete.
