If any of the codes are displayed, service as necessary according to the On Demand instructions of the Key On - Engine Off Test. If none of the listed codes are displayed, leave ignition on and proceed with test.

Measure voltage. If voltage is 10 volts or less, replace TP sensor and repeat Quick Test. If voltage is more than 10 volts, check throttle linkages for sticking or binding, repair as necessary, and repeat Quick Test.
