MANIFOLD ABSOLUTE PRESSURE SENSOR ON-VEHICLE INSPECTION

PROCEDURE

1. CHECK VACUUM SENSOR ASSEMBLY

   
   
   1. 

      *a	Front view of wire harness connector (to Vacuum Sensor Assembly)

      Inspect the power source voltage.

      
      

      1. Disconnect the vacuum sensor assembly connector.

      2. Turn the engine switch on (IG).

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

         Standard Voltage
         Tester Connection Switch Condition Specified Condition 3 (VC) - 1 (E2) Engine switch on (IG) 4.75 to 5.25 V

      4. Turn the engine switch off.

      5. Reconnect the vacuum sensor assembly connector.

   2. Check the vacuum and pressure.

      
      

      1. Connect the GTS to the DLC3.

      2. Turn the engine switch on (IG) and turn the GTS on.

      3. Enter the following menus: Powertrain / Engine and ECT / Data List / MAP.

         
         Powertrain > Engine and ECT > Data List

         Tester Display
         MAP

      4. Read the MAP value.

         OK
         Condition Specified Condition No pressure applied Same as atmospheric pressure Vacuum applied Indicates vacuum Pressure applied Indicates pressure

         If the result is not as specified, replace the vacuum sensor assembly.
