  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 1.5 volts or less with throttle closed, replace TPS. Perform TEST VER-2  . If voltage is 1.5 volts or less with throttle closed, watch voltage while slowly opening throttle wide open. If voltage change was not smooth, replace TPS. Perform TEST VER-2. If voltage change was smooth, go to next step.
  3. If maximum voltage was not at least 3.4 volts at wide open throttle, replace TPS. Perform TEST VER-2. If maximum voltage was at least 3.4 volts at wide open throttle, TPS is functioning properly. Test is complete.
