Re: Testing a Throttle Position Sensor 700 1990

posted by  someone claiming to be bob on  Thu Oct 4 14:00 CST 2001 [RELATED]

You can also test it with the OBD diagnostic socket. Ignition switch on, engine off. Plug the test lead in to socket 2. Place something in the throttle linkage to prevent the switch from closing. Press the button on the diagnostic link twice, the light should flash and you are in diagnostic mode 2. Now, rotate the throttle to WOT and hold it there. The light will stop flashing, and will begin to flash a response code. For WOT, the code is 333. Then the light will flash rapidly again. Now let the throttle return to idle. If ok, a response code of 332 will flash.
