Details On DTCs

System malfunction location	Boost air temperature sensor circuit range/performance problem
Detection condition	•  The difference in intake air temperature detected by IAT sensor No.1 and boost air temperature sensor is 40 °C {104 °F} or more and the difference in intake air temperature detected by the boost air temperature sensor and IAT sensor No.2 is 40 °C {104 °F} or more for a continuous 20 s. Preconditions •  Period vehicle being left: 6 h or more •  Battery voltage: above 8 V •  The following DTCs are not detected: ―  Boost air temperature sensor: P00EA:00, P00EB:00 ―  IAT Sensor No.1: P0112:00, P0113:00 ―  IAT Sensor No.2: P0097:00, P0098:00
Fail-safe	•  Not applicable
Possible cause	•  Boost pressure sensor/Boost air temperature sensor connector or terminals malfunction •  PCM connector or terminals malfunction •  Short to ground in boost pressure sensor signal circuit •  Short circuit in boost air temperature sensor signal circuit and ground circuit •  Boost air temperature sensor malfunction •  PCM malfunction

Diagnostic Procedure

Step	Inspection	Results	Action
1	RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION •  Record the freeze frame data/snapshot data. Note •  Recording can be facilitated using the screen capture function of the PC.	—	Go to the next step.
2	VERIFY RELATED REPAIR INFORMATION OR SERVICE INFORMATION AVAILABILITY •  Verify related Service Bulletins, on-line repair information, or Service Information availability. •  Is any related Information available?	Yes	Perform repair or diagnosis according to the available information. •  If the vehicle is not repaired, go to the next step.
		No	Go to the next step.
3	INSPECT BOOST PRESSURE SENSOR/BOOST AIR TEMPERATURE SENSOR CONNECTOR FOR MALFUNCTION •  Inspect the applicable connector and terminal. (See CONNECTOR INSPECTION.) •  Are the connector and terminal normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification.
4	INSPECT PCM CONNECTOR FOR MALFUNCTION •  Inspect the applicable connector and terminal. (See CONNECTOR INSPECTION.) •  Are the connector and terminal normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification.
5	INSPECT BOOST AIR TEMPERATURE SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND •  Inspect the applicable circuit for a short to ground. (See CIRCUIT INSPECTION.) •  Is the circuit normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification.
6	INSPECT BOOST AIR TEMPERATURE SENSOR SIGNAL CIRCUIT AND GROUND CIRCUIT FOR SHORT CIRCUIT •  Inspect the applicable circuits for a short circuit. (See CIRCUIT INSPECTION.) •  Is the circuit normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification.
7	INSPECT BOOST AIR TEMPERATURE SENSOR •  Perform the boost air temperature sensor Inspection. (See BOOST AIR TEMPERATURE SENSOR INSPECTION [SKYACTIV-X 2.0].) •  Is the part normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification. (See BOOST AIR PRESSURE SENSOR/BOOST AIR TEMPERATURE SENSOR REMOVAL/INSTALLATION [SKYACTIV-X 2.0].)
Repair completion verification 1	PURPOSE: VERIFY THAT VEHICLE IS REPAIRED •  Install/connect the part removed/disconnected during the troubleshooting procedure. •  Clear the DTC recorded in the memory. (See CLEARING DTC.) •  Replicate the vehicle conditions at the time the DTC was detected using the following procedure. ―  Perform the KOEO or KOER self test. (See DTC INSPECTION.) •  Perform the DTC inspection for the PCM. (See DTC INSPECTION.) •  Is the same Pending DTC present?	Yes	Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error. (See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(E)].) If the CAN communication is normal, perform the diagnosis from Step 1. •  If the malfunction recurs, replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [SKYACTIV-X 2.0].)
		No	Go to the next step.
Repair completion verification 2	PURPOSE: VERIFY IF OTHER DTCs DISPLAYED •  Perform the DTC inspection. (See DTC INSPECTION.) •  Are any other DTCs displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting.
		No	DTC troubleshooting completed.
