Test NTC-5A - Checking TPS Calibration
WARNING: This page is about a different car, the 1994 Eagle Vision, 1994 Dodge Intrepid, and 1994 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
After each repair, perform TEST VER-2 .
- Turn engine off. Turn ignition on. Using DRB, read Throttle Position Sensor (TPS) voltage. Ensure throttle is fully closed and against throttle stop. If voltage is not 1.2 volts or less with throttle closed, replace TPS. If voltage is 1.2 volts or less with throttle closed, go to next step.
- Observe voltage while slowly opening throttle wide open. If voltage change is not smooth, replace TPS. If maximum voltage is not at least 3.7 volts at wide open throttle, replace TPS. If voltage change is smooth and maximum voltage is at least 3.7 volts at wide open throttle, test is complete.
