Throttle Position Sensor (TPS)

TPS should input a .5-volt reference signal to TCM at closed throttle and approximately 4.5-volt signal at full throttle. Voltage should change smoothly as throttle valve is opened and closed. If voltage is not correct, check TPS wiring circuit. See WIRING DIAGRAMS  . Individual component testing of throttle position sensor is not available from manufacturer.

NOTE: If problem in TPS exists, sensor may set Fault Code No. 3 in TCM. See RETRIEVING CODES  under SELF-DIAGNOSTIC SYSTEM.
