Test NTC-5A - Checking TP Sensor Calibration
WARNING: This page is about a different car, the 1995 Plymouth Voyager, 1995 Plymouth Grand Voyager, 1995 Dodge Grand Caravan, and 1995 Dodge Caravan. However, it is still accessible from the selected car via links, so may be relevant.
- 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, watch voltage while slowly opening throttle to wide open position. 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 (WOT), replace TP sensor. Perform TEST VER-2. If maximum voltage is at least 3.4 volts at WOT, TP sensor is functioning properly. Test is complete.
