TP Sensor Inspection (TBI)

Disconnect TP sensor connector. Using hand vacuum pump, apply 20 in. Hg vacuum to throttle opener to move throttle lever to idle position. Using ohmmeter, check resistance between specified terminals of TP sensor connector with proper shim thickness gauge inserted between throttle valve lever and stop screw. See the THROTTLE POSITION (TP) SENSOR RESISTANCE  table. See Figure . Adjust sensor if reading are not as specified.
