Throttle Angle Sensor

Throttle angle sensor should input a 0.3-volt reference signal to ATCU 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 angle sensor wiring circuit. See WIRING DIAGRAMS at the end of this article.

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