Checking Throttle Position (TP) Sensor Calibration

WARNING: This page is about a different car, the 1995 Dodge Stratus, 1995 Dodge Avenger, 1995 Chrysler Sebring, and 1995 Chrysler Cirrus. However, it is still accessible from the selected car via links, so may be relevant.
  1. Turn ignition off. Inspect throttle linkage and cruise control linkage (if equipped) for binding. If linkage is binding, repair as necessary. Perform TEST VER-2 . If linkage is not binding, turn ignition on.
  2. Ensure throttle is fully closed. Using scan tool, read Throttle Position (TP) sensor voltage. If voltage is 1.5 volts or less, replace TP sensor. Perform TEST VER-2. If voltage is not 1.5 volts or less, go to next step.
  3. While observing scan tool voltage, slowly open throttle to Wide Open Throttle (WOT). If voltage change is not smooth, replace TP sensor. Perform TEST VER-2. If voltage change is smooth, go to next step.
  4. 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 wide open throttle, TP sensor is functioning properly. Test is complete.
