Checking Throttle Position (TP) Sensor Calibration
- 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.
- 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.
- 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.
- 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.
