AIR FUEL RATIO (A/F) SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 2.2]

id0140z7899700

Warning

• A hot engine and exhaust system can cause severe burns. Turn off the engine and wait until they are cool before removing the exhaust system.

Caution

• Do not allow flammable objects such as the taping for bundling a wiring harness to come into contact with the catalytic converter.

Note

• If the A/F sensor is replaced, perform the “Operation After Replacing A/F Sensor” procedure. (See Operation After Replacing A/F Sensor.)

• If penetrant lubricating spray penetrates the airflow hole of the A/F sensor, it could cause interference with the A/F sensor function.

• When removing the A/F sensor, wrap a rag around the lower position so that penetrant lubricating spray does not get sprayed into the airflow hole.

Operation After Replacing A/F Sensor

1. If the A/F sensor is replaced, perform the following procedure.

Step

Action

Page

1

Perform the A/F sensor data reset procedure.

(See AIR FUEL RATIO (A/F) SENSOR DATA RESET [SKYACTIV-D 2.2].)

2

Switch the ignition off.

—

3

Wait for 20 s.

—

4

Perform the KOEO self test procedure.

(See KOEO/KOER SELF TEST [SKYACTIV-D 2.2].)

5

Start the engine.

—

6

Verify that the check engine light does not illuminate.

—

7

Perform the KOER self test procedure.

(See KOEO/KOER SELF TEST [SKYACTIV-D 2.2].)

8

Perform the compulsory diesel particulate filter regeneration procedure.

(See COMPULSORY DIESEL PARTICULATE FILTER REGENERATION [SKYACTIV-D 2.2].)

9

Perform the following procedure.

Caution

•  If the M-MDS is connected to the DLC-2, disconnect the M-MDS. Otherwise, it could adversely affect safety when performing the procedure.

1.  Vehicle is traveling at a speed of 50 km/h {31 mph} or more.

2.  Release the accelerator pedal at a vehicle speed of 50 km/h {31 mph} or more and maintain this condition for 6 s.

—

10

Verify that the PID “O2S11_CAL” value is other than 0.

(See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 2.2].)

1. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].)

2. Lift up the vehicle.

3. Remove the following parts:

(1) Front under cover No.2 (2WD) (See FRONT UNDER COVER No.2 REMOVAL/INSTALLATION.)

(2) Splash shield (See SPLASH SHIELD REMOVAL/INSTALLATION.)

(3) Seal rubber (No.1) and noise suppression cover (No.1) (See TIMING CHAIN REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)

4. Disconnect the A/F sensor connector.

5. Remove the plate (exhaust system). (See EXHAUST SYSTEM REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)

6. Remove the wiring harness from the wire clip A and B. (See Assembly of Wiring Harness to Wire Clip Note.)

ac5wzw00004501

7. Loosen the nuts (center bearing support) of the propeller shaft. (4WD) (See PROPELLER SHAFT REMOVAL/INSTALLATION.)

8. Disconnect the propeller shaft on the front side and set the propeller shaft onto the front crossmember. (4WD) (See PROPELLER SHAFT REMOVAL/INSTALLATION.)

9. Remove the A/F sensor using the SST.

10. Install in the reverse order of removal.

11. Perform operation after replacing A/F sensor. (See Operation After Replacing A/F Sensor.)

Assembly of Wiring Harness to Wire Clip Note

• Secure the wiring harness to the wire clip A so that the band on the wiring harness is positioned to the left side of the wire clip A.

ac5wzw00004503

• Secure the wiring harness to the wire clip B so that the band on the wiring harness is positioned to the both sides of the wire clip B.
