  2. If a HI-SCAN (PRO) is not used, connect a digital type voltmeter between ground and TPS output terminal.
  3. Turn the ignition switch to the ON position (do not start engine) and check that TPS output voltage is as specified. If a HI-SCAN (PRO) is used, read the TPS voltage. If it is out of specification, loosen TPS mounting screws and adjust by turning the TPS.
    NOTE: Turning the TPS clockwise increases the output voltage. Tighten the screws securely after adjustment.
  4. Turn the ignition switch to the OFF position.
