How to Test Throttle Position Sensor? 900 1994

posted by  someone claiming to be bob on  Sun Nov 14 16:21 CST 2004 [RELATED]

To test throttle position sensor on LH-2.4. Go to the diagnostic socket at the strut tower, and access A-2 as if reading fault codes. Turn on ignition switch, rotate throttle spindle midway between idle and WOT and hold it there. Press the button on diagnostic socket 2 times while holding throttle. When the LED starts to flash, turn throttle to WOT. The led should stop flashing briefly and flash out a response code of 3-3-3, throttle switch ok at WOT. If this code comes up, wot portion of signal is ok. When the light flashes rapidly again, release throttle to idle. LED should flash a 3-3-2 code, throttle switch ok at idle.
