Diagnostic Procedure

DTC P034000 (SKYACTIV-G 2.0) 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.
1		No	Record the FREEZE FRAME DATA (Mode 2)/snapshot data on the repair order, then 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	INSPECT INTAKE CMP SENSOR CONNECTOR CONDITION Switch the ignition to off. Disconnect the intake CMP 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 13.
3		No	Go to the next step.
4	INSPECT INTAKE CMP SENSOR POWER SUPPLY CIRCUIT FOR SHORT TO GROUND OR OPEN CIRCUIT Verify that the intake CMP sensor connector is disconnected. Switch the ignition ON (engine off or on). Measure the voltage at the intake CMP sensor terminal C (wiring harness-side). Is the voltage B+ ?	Yes	Go to the next step.
4		No	Inspect the ENGINE1 15 A fuse. If the fuse is blown: Repair or replace the wiring harness for a possible short to ground. Replace the fuse. If the fuse is deteriorated: Replace the fuse. If the fuse is normal: Repair or replace the wiring harness for a possible open circuit. Go to Step 13.
5	INSPECT INTAKE CMP SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND Verify that the intake CMP sensor connector is disconnected. Switch the ignition to off. Inspect for continuity between intake CMP sensor terminal A (wiring harness-side) and body ground. Is there continuity?	Yes	If the short to ground circuit could be detected in the wiring harness: Repair or replace the wiring harness for a possible short to ground. If the short to ground circuit could not be detected in the wiring harness: Replace the PCM (short to ground in the PCM internal circuit). (See PCM REMOVAL/INSTALLATION [SKYACTIV-G 2.0] ). Go to Step 13.
5		No	Go to the next step.
6	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 13.
6		No	Go to the next step.
7	INSPECT INTAKE CMP SENSOR SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY Verify that the intake CMP sensor and PCM connectors are disconnected. Switch the ignition ON (engine off or on). Measure the voltage at the intake CMP sensor terminal A (wiring harness-side). Is the voltage 0 V ?	Yes	Go to the next step.
7		No	Repair or replace the wiring harness for a possible short to power supply, then go to Step 13.
8	INSPECT INTAKE CMP SENSOR SIGNAL CIRCUIT AND GROUND CIRCUIT FOR SHORT TO EACH OTHER Verify that the intake CMP sensor and PCM connectors are disconnected. Switch the ignition to off. Inspect for continuity between intake CMP sensor terminals A and B (wiring harness-side). Is there continuity?	Yes	Repair or replace the wiring harness for a possible short to each other, then go to Step 13.
8		No	Go to the next step.
9	INSPECT INTAKE CMP SENSOR CIRCUIT FOR OPEN CIRCUIT Verify that the intake CMP sensor and PCM connectors are disconnected. Inspect for continuity between the following terminals (wiring harness-side): Intake CMP sensor terminal A-PCM terminal 1Y Intake CMP sensor terminal B-PCM terminal 1AC Is there continuity?	Yes	Go to the next step.
9		No	Repair or replace the wiring harness for a possible open circuit, then go to Step 13.
10	INSPECT INTAKE CMP SENSOR Inspect the intake CMP sensor. (See CAMSHAFT POSITION (CMP) SENSOR INSPECTION [SKYACTIV-G 2.0] ). Is there any malfunction?	Yes	Replace the intake CMP sensor, then go to Step 13. (See CAMSHAFT POSITION (CMP) SENSOR REMOVAL/INSTALLATION [SKYACTIV-G 2.0] ).
10		No	Go to the next step.
11	INSPECT CKP SENSOR CONNECTOR CONDITION Switch the ignition to off. Disconnect the CKP 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 13.
11		No	Go to the next step.
12	VERIFY VALVE TIMING MECHANISM INSTALLATION Verify the valve timing mechanism installation for the following parts: Timing chain Intake camshaft sprocket lock bolt Crankshaft pulley lock bolt Is the valve timing mechanism installed correctly?	Yes	Go to the next step.
12		No	Reinstall the following parts correctly, then go to the next step. Timing chain Intake camshaft sprocket Crankshaft pulley
13	VERIFY DTC TROUBLESHOOTING COMPLETED Make sure to reconnect all disconnected connectors. Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [SKYACTIV-G 2.0] ). Start the engine. Perform the KOER self test. (See KOEO/KOER SELF TEST [SKYACTIV-G 2.0] ). 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 2.0] ). Go to the next step.
13		No	Go to the next step.
14	VERIFY AFTER REPAIR PROCEDURE Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE [SKYACTIV-G 2.0] ). Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [SKYACTIV-G 2.0] ).
14		No	DTC troubleshooting completed.
