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 WDS or equivalent to the DLC-2.
  2. Turn the ignition switch to ON (Engine OFF).
  3. Select MAP PID on the WDS or equivalent.
  4. 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.
