Test NTC-7A: Checking Throttle Position Sensor

NOTE: Perform TEST NTC-1A  or TEST NTC-6A  before proceeding.
  1. Turn ignition off. Check throttle cable for binding. If vehicle is equipped with cruise control, also check cruise control cable for binding. If either cable is binding, repair as necessary. Perform TEST VER-2A . If either cable is not binding, go to next step.
  2. Turn ignition on. Using scan tool, read Throttle Position (TP) sensor voltage. Ensure throttle is fully closed against throttle stop. If voltage is 1.5 volts or less, go to next step. If voltage is more than 1.5 volts, replace TP sensor. Perform TEST VER-2A .
  3. Observe TP sensor voltage on scan tool while slowly opening throttle to Wide Open Throttle (WOT). If voltage change was smooth, go to next step. If voltage change was not smooth, replace TP sensor. Perform TEST VER-2A .
  4. If voltage was at least 3.4 volts at WOT, TP sensor is functioning properly. Test is complete. If voltage was not at least 3.4 volts at WOT, replace TP sensor. Perform TEST VER-2A .
