Kia Carens. Instruction — part 70

2001 > 1.8L DOHC >

Removal

Do not drop or subject the sensor to shock. Do not put objects inside the sensor.

1. Disconnect mass air flow sensor connect.

2. Loosen air intake hose retaining clamps on both sides of mass air flow sensor.

3. Disconnect air intake hose from mass air flow sensor.

4. Remove two bolts attaching mass air flow sensor to mounting bracket.

5. Remove mass air flow sensor.

Installation

1. Attach mass air flow sensor to air intake hose and to mounting bracket.

2. Replace two colts to retain mass air flow sensor to mounting bracket.

Tightening torque: 69~69.3 lb-in(7.8~10.8 N·m, 0.8~1 kg-m)

3. Reconnect air intake hose to the mass air flow sensor.

4. Tighten bolts of retaining clamps on both sides of mass air flow sensor.

5. Reconnect mass air flow sensor connector to sensor.

6. Warm up engine to normal operating temperature and let engine idle.

7. Connect voltmeter between terminal D (YEL/RED wire) and ground.

8. Verify that the voltage varies between 0.8V~1.2V.

9. Rev up engine and verify that voltage varies between 3.5V~4V.

10. If voltage is not within specification, replce mass air flow sensor.

Inspection

1. Check mass air flow sensor for damage, replace if necessary.
