DTC P16B5:00 [PCM (SKYACTIV-D 2.2)]

id0102j5232200

DTC P16B5:00

Malfunction in PCM: Exhaust gas temperature sensor No.5 control transistor malfunction
DETECTION CONDITION
•  If any of the following conditions is met for 6 s
―  When the transistor in the exhaust gas temperature sensor No.5 operates, the transistor's downstream voltage is 2.083 V or less.
Diagnostic support note
•  This is a continuous monitor (CCM).
•  The check engine light illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
•  PENDING CODE is available if the PCM detects the above malfunction condition during first drive cycle.
•  FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
•  DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION
•  Not applicable
POSSIBLE CAUSE
•  Exhaust gas temperature sensor No.5 malfunction
•  PCM malfunction

Diagnostic Procedure

STEP

INSPECTION

RESULTS

ACTION
1
VERIFY RELATED REPAIR INFORMATION AVAILABILITY
•  Verify related Service Bulletins and/or on-line repair information availability.
•  Is any related repair information available?
Yes
Perform repair or diagnosis according to the available repair information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
2
IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA (MODE 2)
•  Is the DTC P16B5:00 on FREEZE FRAME DATA (Mode 2)?
Yes
Go to the next step.
No
Go to the troubleshooting procedure for DTC on FREEZE FRAME DATA (Mode 2).
(See DTC TABLE [PCM (SKYACTIV-D 2.2)].)
3
RECORD VEHICLE STATUS AT TIME OF DTC DETECTION TO UTILIZE WITH REPEATABILITY VERIFICATION
Note
•  Recording can be facilitated using the screen capture function of the PC.
•  Record the FREEZE FRAME DATA (Mode 2)/snapshot data on the repair order.

Go to the next step.
4
INSPECT EXHAUST GAS TEMPERATURE SENSOR No.5
•  Inspect the exhaust gas temperature sensor No.5.
•  Is there any malfunction?
Yes
Replace the exhaust gas temperature sensor No.5, then go to the next step.
(See EXHAUST GAS TEMPERATURE SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
No
Go to the next step.
5
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Always reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Switch the ignition ON (engine off).
•  Access the EGT_B1S5 PID using the M-MDS.
•  Verify that the PID EGT_B1S5 monitoring value is 125 °C {257 °F}(temperature in which transistor always turns off) or less and wait for 10 s or more.
•  Start the engine.
•  Drive the vehicle until the PID EGT_B1S5 monitoring value reaches 155 °C {311 °F} or more (temperature in which transistor always turns on) to warm up the engine.
•  Perform the Pending Trouble Code Access Procedure.
•  Is the PENDING CODE for this DTC present?
Yes
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
No
Go to the next step.
6
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [PCM (SKYACTIV-D 2.2)].)
No
DTC troubleshooting completed.
