Intake Sensor With 7 Inch Display

B2581, B2582 INTAKE SENSOR





Description

INTAKE SENSOR





- Intake sensor (1) is located on the evaporator (2).
- The intake sensor converts the evaporator passing air temperature detected with thermistor into the voltage, and the A/C auto amp. inputs this voltage.

INTAKE TEMPERATURE CORRECTION
- The A/C auto amp. inputs the temperature detected with the intake sensor as the evaporator passing air temperature.
- Perform the correction of the temperature detected with the intake sensor for air conditioning control.
- The A/C auto amp. performs the correction so that the recognition intake temperature changes depending on the difference between the detected intake temperature and the recognition intake temperature. If the difference is large, the changing is early. The changing becomes slow as the difference becomes small.

DTC CONFIRMATION PROCEDURE
1.PERFORM SELF-DIAGNOSIS
With CONSULT-III
1. Perform the "SELF-DIAGNOSIS".
2. Check if any DTC is detected in the self-diagnostic results.

NOTE:
If DTC is displayed along with DTC "U1000" or "U1010", first diagnose the DTC "U1000" or "U1010". Climate Control With 7 Inch Display or Climate Control With 7 Inch Display.
Is DTC "B2581" or "B2582" displayed?
YES - Perform the diagnosis for the intake sensor. SEE Diagnosis Procedure.
NO - INSPECTION END




Diagnosis Procedure
1.CHECK INTAKE SENSOR POWER SUPPLY CIRCUIT
1. Turn the ignition switch OFF.
2. Disconnect the intake sensor connector.
3. Turn the ignition switch ON.
4. Check voltage between intake sensor harness connector and ground.





Is the inspection result normal?
YES - GO TO 2.
NO - GO TO 4.
2.CHECK INTAKE SENSOR CIRCUIT CONTINUITY
1. Turn the ignition switch OFF.
2. Disconnect the A/C auto amp. connector.
3. Check for continuity between the intake sensor harness connector and A/C auto amp. harness connector.





Is the inspection result normal?
YES - GO TO 3.
NO - Repair the harnesses or connectors.
3.CHECK INTAKE SENSOR
Check the intake sensor components. SEE Component Inspection.
Is the inspection result normal?
YES - Replace the A/C auto amp.
NO - Replace the intake sensor.
4.CHECK INTAKE SENSOR CIRCUIT CONTINUITY
1. Turn the ignition switch OFF.
2. Disconnect the A/C auto amp. connector.
3. Check for continuity between the intake sensor harness connector and A/C auto amp. harness connector.





4. Check for continuity between intake sensor harness connector and ground.





Is the inspection result normal?
YES - Replace the A/C auto amp.
NO - Repair the harnesses or connectors.




Component Inspection
1.CHECK INTAKE SENSOR
1. Turn the ignition switch OFF.
2. Disconnect the intake sensor connector. Intake Sensor Exploded View With 7 Inch Display.
3. Check the resistance between the intake sensor terminals. Refer to the applicable table for the normal value.





Is the inspection result normal?
YES - INSPECTION END
NO - Replace the intake sensor.
