DTC P007B:00

Boost air temperature sensor circuit range/performance problem
DETECTION CONDITION
•  With the following conditions met, a condition has continued for 15 s in which difference in intake air temperature measured by the IAT sensor No.1 and boost air temperature sensor is 150 °C {270 °F} or more and difference in intake air temperature measured by boost air temperature sensor and IAT sensor No.2 is 150 °C {270 °F} or more.
MONITORING CONDITIONS
―  Period vehicle being left: 6 h or more
―  Battery voltage: 10 V or more
―  Within 20 s after engine start
―  The following DTCs are not detected:
•  Boost air temperature sensor: P007C:00, P007D:00
•  IAT sensor No.1: P0112:00, P0113:00
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
•  Inhibits the two-stage turbo control.
•  Inhibits the EGR control.
•  Inhibits engine-stop by operating the i-stop function.
•  PCM restricts engine-transaxle integration control.
POSSIBLE CAUSE
•  Boost air temperature sensor connector or terminals malfunction
•  Boost air temperature sensor malfunction
•  PCM connector or terminals malfunction
•  PCM malfunction

Diagnostic Procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA (MODE 2)/SNAPSHOT DATA HAS BEEN RECORDED
•  Has the FREEZE FRAME DATA (Mode 2)/snapshot data been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA (Mode 2)/snapshot data on the repair order, then go to the next step.
2
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes
Perform repair or diagnosis according to the available Service Information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
INSPECT BOOST AIR TEMPERATURE SENSOR CONNECTOR CONDITION
•  Switch the ignition off.
•  Disconnect the boost air temperature sensor connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the connector and/or terminals, then go to Step 6.
No
Go to the next step.
4
INSPECT BOOST AIR TEMPERATURE SENSOR
•  Inspect the boost air temperature sensor.
•  Is there any malfunction?
Yes
Replace the boost air temperature sensor, then go to Step 6.
(See BOOST AIR TEMPERATURE SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
No
Go to the next step.
5
INSPECT PCM CONNECTOR CONDITION
•  Disconnect the PCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the connector and/or terminals, then go to the next step.
No
Go to the next step.
6
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Always reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Leave the vehicle for 6 hours or more.
•  Start the engine and idle it for 1 min.
•  Perform the DTC Reading Procedure.
•  Is the same DTC present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the PCM.
Go to the next step.
No
Go to the next step.
7
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [SKYACTIV-D 2.2].)
No
DTC troubleshooting completed.
