DIAGNOSTIC PROCEDURE FOR INTAKE SENSOR
SYMPTOM: Intake sensor circuit is open or shorted. Using the CONSULT-II, DTC B2581 or B2582 is displayed. Without a CONSULT-II code 56 or 57 is indicated on front air control as a result of conducting self-diagnosis.
COMPONENT INSPECTION
Intake Sensor
After disconnecting intake sensor connector, measure resistance between terminals 1 and 2 at sensor harness side, using the table above.
If NG, replace intake sensor.
