Diagnostic Procedure

DTC P0223:00 PCM (SKYACTIV-G 2.5 - WITH CYLINDER DEACTIVATION) DIAGNOSTIC PROCEDURE

STEP	INSPECTION	RESULTS	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 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.
2		No	Go to the next step.
3	DETERMINE IF TP SENSOR NO. 2 OR WIRING HARNESS MALFUNCTION Access the TP2 PID using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION))] .) Verify the TP2 PID value. Is the TP2 PID value 5 V or B+?	Yes	Go to Step 7.
3		No	Go to the next step.
4	INSPECT THROTTLE BODY CONNECTOR CONDITION Switch the ignition off. Disconnect the throttle body 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 9.
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 9.
5		No	Go to the next step.
6	INSPECT TP SENSOR NO. 2 Reconnect all disconnected connectors. Inspect the TP sensor No. 2. (See THROTTLE POSITION (TP) SENSOR INSPECTION [SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION)] .) Is there any malfunction?	Yes	Replace the throttle body, then go to Step 9. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION)] .)
6		No	Go to Step 9.
7	INSPECT TP SENSOR NO. 2 SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY Switch the ignition off. Disconnect the throttle body connector. Access the TP2 PID using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION))] .) Verify the TP2 PID value. Is the TP2 PID value 5 V or B+?	Yes	Refer to the wiring diagram and verify whether or not there is a common connector between throttle body terminal C and PCM terminal 1V. 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 9.
7		No	Go to the next step.
8	INSPECT TP SENSOR NO. 2 GROUND CIRCUIT FOR OPEN CIRCUIT Verify that the throttle body connector is disconnected. Switch the ignition off. Disconnect the PCM connector. Inspect for continuity between throttle body terminal D (wiring harness-side) and PCM terminal 1R (wiring harness-side). Is there continuity?	Yes	Replace the throttle body, then go to the next step. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION)] .)
8		No	Refer to the wiring diagram and verify whether or not there is a common connector between throttle body terminal D and PCM terminal 1R. 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.
9	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 2.5 (WITH CYLINDER DEACTIVATION))] .) Perform the KOEO or KOER self test. (See KOEO/KOER SELF TEST [PCM (SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION))] .) Is the same DTC present?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION)] .) Go to the next step.
9		No	Go to the next step.
10	VERIFY AFTER REPAIR PROCEDURE Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE [PCM (SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION))] .) Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [PCM (SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION))] .)
10		No	DTC troubleshooting completed.
