Manifold Absolute Pressure (Map) Sensor Inspection: Notes

NOTE:
  • Perform the following inspection only when directed.
  • The following vacuum values are indicated by relative pressure from the MAP sensor.
  1. Connect the M-MDS to the DLC-2.
  2. Turn the ignition switch to ON (Engine off).
  3. Select MAP PID on the M-MDS.
  4. Verify that the MAP PID (pressure) and barometric pressure are practically equal.
    • If not as verified, perform the "Circuit Open/Short Inspection".
      • If there is no open or short circuit, replace the MAP sensor.
    • If as verified, go to next step.
  5. Apply vacuum of-25.0 kPa {-187 mmHg, -7.38 inHg}  to the MAP sensor, and verify that the MAP variation from that of Step 4 is approx. 25.0 kPa {187 mmHg, 7.38 inHg}. 
    • If not as verified, perform the "Circuit Open/Short inspection".
      • If there is no open or short circuit, replace the barometric pressure sensor. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION .)
