Throttle Position Sensor
NOTE:
If problem in throttle position sensor exists, throttle position sensor exits, throttle position sensor may set Fault Code No. 3 in TCM. See RETRIEVING FAULT CODES
under SELF-DIAGNOSTIC SYSTEM.
Throttle position sensor should input a 5-volt reference signal to TCM at closed throttle: At full throttle, signal should be approximately 4.5 volts. Voltage should change smoothly as throttle valve is opened and closed. If voltage is not as specified, check throttle position sensor wiring circuit. See WIRING DIAGRAMS . Individual component testing of throttle position sensor is not available from manufacturer.
