Throttle Angle Sensor

Throttle angle sensor should input a .5-volt reference signal to ATCU 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 throttle angle sensor wiring circuit. See WIRING DIAGRAMS at the end of this article. See Figure .

NOTE: If problem in throttle angle sensor exists, throttle angle sensor may set Fault Code No. 7 in PGM-FI ECU. See the TESTS W/CODES article in the ENGINE PERFORMANCE section.
