Test NTC-5A - Checking TPS Calibration

WARNING: This page is about a different car, the 1994 Plymouth Sundance, 1994 Plymouth Acclaim, 1994 Dodge Spirit, 1994 Dodge Shadow, and 1994 Chrysler LeBaron. However, it is still accessible from the selected car via links, so may be relevant.
  1. Turn engine off. Turn ignition on. Using DRB, read Throttle Position Sensor (TPS) voltage. Ensure throttle is fully closed and against throttle stop.
  2. If voltage is not one volt or less with throttle closed, replace TPS. Perform TEST VER-2. If voltage is one volt or less with throttle closed, watch voltage while slowly opening throttle wide open. If voltage change is not smooth, replace TPS. Perform TEST VER-2  . If voltage change is smooth, go to next step.
  3. If maximum voltage is not at least 3.6 volts at wide open throttle, replace TPS. Perform TEST VER-2. If maximum voltage is at least 3.6 volts at wide open throttle, TPS is functioning properly. Test is complete.
