DIAGNOSTIC PROCEDURE CHART

Step	Check	Yes	No
1 CHECK CURRENT DATA. Start the engine. Read the data of tumble generator valve position sensor signal using Subaru Select Monitor or general scan tool. NOTE: Subaru Select Monitor For detailed operation procedure, refer to "READ CURRENT DATA FOR ENGINE" in SUBARU SELECT MONITOR . General scan tool For detailed operation procedure, refer to the general scan tool operation manual.	Is the voltage less than 0.2 V?	Go to step 2.	Even if the malfunction indicator light illuminates, the circuit has returned to a normal condition at this time. Reproduce the fault condition, and reperform the check. NOTE: In this case, there may be a temporary connector contact failure.
2 CHECK POWER SUPPLY OF TUMBLE GENERATOR VALVE POSITION SENSOR. Turn the ignition switch to OFF. Disconnect the connector from tumble generator valve position sensor. Turn the ignition switch to ON. Measure the voltage between the tumble generator valve position sensor connector and engine ground. Connector & terminal (E54) No. 1 (+) - Engine ground (-):	Is the voltage 4.5 V or more?	Go to step 3.	Repair the harness and connector. NOTE: In this case, repair the following item: Open circuit of harness between ECM and tumble generator valve position sensor connector Poor contact in ECM connector Poor contact of coupling connector
3 CHECK HARNESS BETWEEN ECM AND TUMBLE GENERATOR VALVE POSITION SENSOR CONNECTOR. Turn the ignition switch to OFF. Disconnect the connectors from ECM. Measure the resistance of harness between ECM and tumble generator valve position sensor connector. Connector & terminal (B134) No. 26 - (E54) No. 3:	Is the resistance less than 1 Ω?	Go to step 4.	Repair the harness and connector. NOTE: In this case, repair the following item: Open circuit of harness between ECM and tumble generator valve position sensor connector Poor contact of coupling connector
4 CHECK HARNESS BETWEEN ECM AND TUMBLE GENERATOR VALVE POSITION SENSOR CONNECTOR. Measure the resistance between ECM and chassis ground. Connector & terminal (B134) No. 26 - Chassis ground:	Is the resistance 1 MΩ or more?	Go to step 5.	Repair the ground short circuit of harness between ECM and tumble generator valve position sensor connector.
5 CHECK POOR CONTACT. Check for poor contact in ECM and tumble generator valve position sensor connector.	Is there poor contact in ECM and tumble generator valve position sensor connector?	Repair the poor contact in ECM or tumble generator valve position sensor connector.	Replace the tumble generator valve position sensor. < Ref. to TUMBLE GENERATOR VALVE POSITION SENSOR .>
