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.

Fuel injector (2pin type)

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	Switch the ignition ON (engine off).	—
5	Perform the KOEO self test procedure.	(See KOEO/KOER SELF TEST [PCM (SKYACTIV-D 2.2)].)
6	Start the engine.	—
7	Verify that the check engine light does not illuminate.	—
8	Perform the KOER self test procedure.	(See KOEO/KOER SELF TEST [PCM (SKYACTIV-D 2.2)].)
9	Perform the compulsory diesel particulate filter regeneration procedure.	(See COMPULSORY DIESEL PARTICULATE FILTER REGENERATION [SKYACTIV-D 2.2].)
10	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.	—
11	Verify that the PID “O2S11_CAL” value is other than 0.	(See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)].)

Fuel injector (6pin type)

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 30 s.	—
4	Switch the ignition ON (engine off).	—
5	Perform the KOEO self test procedure.	(See KOEO/KOER SELF TEST [PCM (SKYACTIV-D 2.2)].)
6	Start the engine.	—
7	Verify that the check engine light does not illuminate.	—
8	Perform the KOER self test procedure.	(See KOEO/KOER SELF TEST [PCM (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. Remove your foot from the accelerator pedal at a vehicle speed of 50 km/h {31 mph} or more.	—
10	Verify that the PID “O2S11_CAL” value is other than 0.	(See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)].)
11	Perform the compulsory diesel particulate filter regeneration procedure.	(See COMPULSORY DIESEL PARTICULATE FILTER REGENERATION [SKYACTIV-D 2.2].)
