VACUUM SENSOR ON-VEHICLE INSPECTION

PROCEDURE

1. INSPECT MANIFOLD ABSOLUTE PRESSURE SENSOR

   
   

   1. Connect the GTS to the DLC3.

   2. Turn the ignition switch to ON with the engine off.

   3. Inspect the manifold absolute pressure sensor.

      
      

      1. Enter the following menus: Powertrain / Engine / Data List / Atmosphere Pressure.

      2. Check the atmosphere pressure.

         OK
         Almost the same as ambient pressure

         Tech Tips

         
         

         • The standard atmospheric pressure is 101 kPa (1.03 kgf/cm2, 14.6 psi).

         • The atmospheric pressure decreases by 1 kPa (0.01 kgf/cm2, 0.1 psi) as the altitude increases by 100 m.

         • The atmospheric pressure varies depending on the weather.
