    2. Measure the voltage according to the value(s) in the table below.

      Standard Voltage:
      Tester Connection
      		Switch Condition
      		Specified Condition
      C83-3 (VC) - C83-1 (E)
      		Ignition switch ON
      		4.75 to 5.25 V

      If the result is not as specified, inspect the wire harness or ECM (LandCruiser RM0000013FU084X.html).

    3. Connect the manifold absolute pressure sensor connector.



  1. Check the power supply.

    1. Turn the ignition switch ON.

    2. Disconnect the vacuum hose from the manifold absolute pressure sensor.
