•  Exhaust gas temperature sensor No.3 transistor: P161F:00, P16B3:00
Diagnostic support note
•  This is a continuous monitor (CCM).
•  The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle.
•  FREEZE FRAME DATA/Snapshot data is available.
•  DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION
•  Limits engine torque.
•  Limits the maximum engine speed.
•  Inhibits the automatic diesel particulate filter regeneration control.
•  Inhibits the manual diesel particulate filter regeneration control.
•  Inhibits the EGR control.
POSSIBLE CAUSE
•  Exhaust gas temperature sensor No.3 connector or terminal malfunction
•  Exhaust gas temperature sensor No.3 malfunction
•  Exhaust gas temperature sensor No.1 connector or terminal malfunction
•  Exhaust gas temperature sensor No.1 malfunction
•  Exhaust gas temperature sensor No.2 connector or terminal malfunction
•  Exhaust gas temperature sensor No.2 malfunction
•  PCM connector or terminal malfunction
•  PCM malfunction

Go to the next step.
2
INSPECT EXHAUST GAS TEMPERATURE SENSOR NO.3 CONNECTOR CONDITION
•  Switch the ignition OFF.
•  Disconnect the exhaust gas temperature sensor No.3 connector.
•  Inspect the connector engagement and connection condition, and inspect the terminals for damage, deformation, corrosion, or disconnection.
•  Is the connector normal?
Yes
Go to the next step.
No
Repair or replace the connector, then go to Step 9.
3
INSPECT EXHAUST GAS TEMPERATURE SENSOR NO.3
•  Inspect exhaust gas temperature sensor No.3.
•  Is exhaust gas temperature sensor No.3 normal?
Yes
Go to the next step.
No
Replace exhaust gas temperature sensor No.3, then go to Step 9.
(See EXHAUST GAS TEMPERATURE SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
4
INSPECT EXHAUST GAS TEMPERATURE SENSOR NO.1 CONNECTOR CONDITION
•  Switch the ignition OFF.
•  Disconnect the exhaust gas temperature sensor No.1 connector.
•  Inspect the connector engagement and connection condition, and inspect the terminals for damage, deformation, corrosion, or disconnection.
•  Is the connector normal?
Yes
Go to the next step.
No
Repair or replace the connector, then go to Step 9.
5
INSPECT EXHAUST GAS TEMPERATURE SENSOR NO.1
•  Inspect exhaust gas temperature sensor No.1.
•  Is exhaust gas temperature sensor No.1 normal?
Yes
Go to the next step.
No
Replace exhaust gas temperature sensor No.1, then go to Step 9.
(See EXHAUST GAS TEMPERATURE SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
6
INSPECT EXHAUST GAS TEMPERATURE SENSOR NO.2 CONNECTOR CONDITION
•  Switch the ignition OFF.
•  Disconnect the exhaust gas temperature sensor No.2 connector.
•  Inspect the connector engagement and connection condition, and inspect the terminals for damage, deformation, corrosion, or disconnection.
•  Is the connector normal?
Yes
Go to the next step.
No
Repair or replace the connector, then go to Step 9.
7
INSPECT EXHAUST GAS TEMPERATURE SENSOR NO.2
•  Inspect exhaust gas temperature sensor No.2.
•  Is exhaust gas temperature sensor No.2 normal?
Yes
Go to the next step.
No
Replace exhaust gas temperature sensor No.2, then go to Step 9.
(See EXHAUST GAS TEMPERATURE SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
8
INSPECT PCM CONNECTOR CONDITION
•  Disconnect the PCM connector.
•  Inspect the connector engagement and connection condition, and inspect the terminals for damage, deformation, corrosion, or disconnection.
•  Is the connector normal?
Yes
Go to the next step.
No
Repair or replace the connector, then go to the next step.
9
VERIFY THAT REPAIRS HAVE BEEN COMPLETED
•  Reconnect all the disconnected connectors.
•  Refer to the [MEMORY CLEARING PROCEDURE] and clear the DTC.
•  Leave the vehicle for 6 h or more.
•  Switch the ignition ON (engine off) or leave for 1 min while idling.
•  Display the DTCs using the M-MDS.
