Diagnostic Procedure

DTC P007D:00 DIAGNOSTIC PROCEDURE

STEP	INSPECTION		ACTION
1	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/snapshot data on the repair order.	-	Go to the next step.
2	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.
2		No	Go to the next step.
3	DETERMINE IF BOOST AIR TEMPERATURE SENSOR OR WIRING HARNESS MALFUNCTION Access the TP_UP_TEMP PID using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.5T)] .) Verify the TP_UP_TEMP PID value. Is the TP_UP_TEMP PID value 5 V or B+?	Yes	Go to Step 7.
3		No	Go to the next step.
4	INSPECT BOOST PRESSURE SENSOR/BOOST AIR TEMPERATURE SENSOR CONNECTOR CONDITION Switch the ignition off. Disconnect the boost pressure sensor/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 10.
4		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 Step 10.
5		No	Go to the next step.
6	INSPECT BOOST AIR TEMPERATURE SENSOR Inspect the boost air temperature sensor. (See BOOST AIR TEMPERATURE SENSOR INSPECTION [SKYACTIV-G 2.5T] .) Is there any malfunction?	Yes	Replace the boost pressure sensor/boost air temperature sensor, then go to Step 10. (See BOOST PRESSURE SENSOR/BOOST AIR TEMPERATURE SENSOR REMOVAL/INSTALLATION [SKYACTIV-G 2.5T] .)
6		No	Go to Step 10.
7	DETERMINE IF BOOST AIR TEMPERATURE SENSOR SIGNAL CIRCUIT OR BOOST AIR TEMPERATURE SENSOR GROUND CIRCUIT MALFUNCTION Switch the ignition off. Disconnect the boost pressure sensor/boost air temperature sensor connector. Access the TP_UP_TEMP PID using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.5T)] .) Verify the TP_UP_TEMP PID value. Is the TP_UP_TEMP PID value 5 V or B+?	Yes	Go to the next step.
7		No	Go to Step 9.
8	INSPECT BOOST AIR TEMPERATURE SENSOR SIGNAL CIRCUIT FOR OPEN CIRCUIT Verify that the boost pressure sensor/boost air temperature sensor connector is disconnected. Switch the ignition off. Disconnect the PCM connector. Inspect for continuity between boost pressure sensor/boost air temperature sensor terminal B (wiring harness-side) and PCM terminal 2U (wiring harness-side). Is there continuity?	Yes	Refer to appropriate wiring diagram and verify whether or not there is a common connector between boost pressure sensor/boost air temperature sensor terminal B and PCM terminal 2U. If there is a common connector: Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to power supply. Repair or replace the malfunctioning part. If there is no common connector: Repair or replace the wiring harness which has a short to power supply. Go to Step 10.
8		No	Refer to appropriate wiring diagram and verify whether or not there is a common connector between boost pressure sensor/boost air temperature sensor terminal B and PCM terminal 2U. If there is a common connector: Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit. Repair or replace the malfunctioning part. If there is no common connector: Repair or replace the wiring harness which has an open circuit. Go to Step 10.
9	INSPECT BOOST AIR TEMPERATURE SENSOR GROUND CIRCUIT FOR OPEN CIRCUIT Verify that the boost pressure sensor/boost air temperature sensor connector is disconnected. Switch the ignition off. Disconnect the PCM connector. Inspect for continuity between boost pressure sensor/boost air temperature sensor terminal A (wiring harness-side) and PCM terminal 2J (wiring harness-side). Is there continuity?	Yes	Replace the boost pressure sensor/boost air temperature sensor, then go to the next step. (See BOOST PRESSURE SENSOR/BOOST AIR TEMPERATURE SENSOR REMOVAL/INSTALLATION [SKYACTIV-G 2.5T] .)
9		No	Refer to appropriate wiring diagram and verify whether or not there is a common connector between boost pressure sensor/boost air temperature sensor terminal A and PCM terminal 2J. If there is a common connector: Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit. Repair or replace the malfunctioning part. If there is no common connector: Repair or replace the wiring harness which has an open circuit. Go to the next step.
10	VERIFY DTC TROUBLESHOOTING COMPLETED Always reconnect all disconnected connectors. Clear the DTC from the PCM memory using the M-MDS. (See CLEARING DTC [PCM (SKYACTIV-G 2.5T)] .) Perform the KOEO or KOER self test. (See KOEO/KOER SELF TEST [PCM (SKYACTIV-G 2.5T)] .) Is the same Pending DTC present?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [SKYACTIV-G 2.5T] .) Go to the next step.
10		No	Go to the next step.
11	VERIFY AFTER REPAIR PROCEDURE Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE [PCM (SKYACTIV-G 2.5T)] .) Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [PCM (SKYACTIV-G 2.5T)] .)
11		No	DTC troubleshooting completed.
