Stop engine. To read output voltage of TPS, insert test probe from rubber cap side of TPS connector and bring it into contact with connector pins. Insert test probes along "GW" lead (TPS output) and "B" lead (ground) of body side harness. See Fig 4
Turn ignition switch to "ON" position without starting engine. Read TPS output voltage. If measurement of output voltage does not agree with .45-.51 V, loosen TPS mounting screws and turn sensor clockwise or counterclockwise until output voltage is .45-.51 V.
Immediately open throttle valve, return it to original position and check for proper output voltage readjusting if necessary. Remove adapter, voltmeter and test probes and reconnect ISC servo harness connector.
Make sure idle speed is normal. Stop engine and turn ignition switch from "OFF" position to "ON" position and after 15 seconds back to "OFF" position. Connect accelerator cable to throttle lever of injection mixer and adjust accelerator cable.
