DTC DETECTING CONDITION:

•

Immediately at fault recognition

•

GENERAL DESCRIPTION

TROUBLE SYMPTOM:

•

Erroneous idling

•

Engine stalls.

•

Poor driving performance

Important
After repair or replacement of faulty parts, conduct Clear Memory Mode and Inspection Mode .

WIRING DIAGRAM:

CHECK CURRENT DATA.

Start the engine.

Read the data of tumble generator valve position sensor signal using Vehicle Diagnostic Interface or OBD-II general scan tool.

Note
•	Vehicle Diagnostic Interface For detailed operation procedure, refer to the “READ CURRENT DATA FOR ENGINE”.
•	OBD-II general scan tool For detailed operation procedures, refer to the OBD-II General Scan Tool Instruction Manual.

Is the voltage less than 0.1 V?

Yes

•

Even if malfunction indicator light lights up, the circuit has returned to a normal condition at this time. A temporary poor contact of the connector may be the cause.

•

Note
In this case, repair the following:
•	Poor contact in tumble generator valve position sensor connector
•	Poor contact in ECM connector
•	Poor contact in coupling connector

CHECK INPUT SIGNAL FOR ECM.

Measure the voltage between ECM connector and chassis ground while throttle valve is fully closed.

Connector & terminal

(B135) No. 9 (+) — Chassis ground (−):

Is the voltage more than 4.5 V?

Yes

CHECK INPUT SIGNAL FOR ECM.

Measure the voltage between ECM connector and chassis ground.

Connector & terminal

(B135) No. 9 (+) — Chassis ground (−):

Shake the ECM harness and connector, while monitoring value of voltage meter. Does the voltage change?

Yes

Repair the poor contact in ECM connector.

Contact Service Center.

CHECK INPUT SIGNAL FOR ECM.

Measure the voltage between ECM connector and chassis ground.

Connector & terminal

(B135) No. 23 (+) — Chassis ground (−):

Is the voltage less than 0.1 V?

Yes

CHECK INPUT SIGNAL FOR ECM. (USING Vehicle Diagnostic Interface)

Measure the voltage between ECM connector and chassis ground.

Shake the ECM harness and connector, while monitoring value of Vehicle Diagnostic Interface. Does the voltage change?

Yes

Repair the poor contact in ECM connector.

CHECK HARNESS BETWEEN ECM AND TUMBLE GENERATOR VALVE POSITION SENSOR CONNECTOR.

Turn the ignition switch to OFF.

Disconnect the connectors from throttle position sensor.

Turn the ignition switch to ON.

Measure the voltage between throttle position sensor connector and engine ground.

Connector & terminal

(E54) No. 1 (+) — Engine ground (−):

Is the voltage more than 4.5 V?

Yes

•

Repair the harness and connector.

•

Note
In this case, repair the following:
•	Open circuit in harness between tumble generator valve position sensor and ECM connector
•	Poor contact in throttle position sensor connector
•	Poor contact in ECM connector
•	Poor contact in coupling connector
•	Poor contact in joint connector

CHECK HARNESS BETWEEN ECM AND TUMBLE GENERATOR VALVE POSITION SENSOR CONNECTOR.

Turn the ignition switch to OFF.

Measure the resistance of harness between ECM connector and throttle position sensor connector.

Connector & terminal

(B135) No. 23 — (E54) No. 3:

Is the resistance less than 1 Ω?

Yes

•

Repair the harness and connector.

•

Note
In this case, repair the following:
•	Open circuit in harness between tumble generator valve position sensor and ECM connector
•	Poor contact in ECM connector
•	Poor contact in tumble generator valve position sensor connector
•	Poor contact in coupling connector

CHECK HARNESS BETWEEN ECM AND THROTTLE POSITION SENSOR CONNECTOR.

Measure the resistance of harness between tumble generator valve position sensor connector and engine ground.

Connector & terminal

(E54) No. 3 — Engine ground:

Is the resistance more than 1 MΩ?

Yes

Repair the ground short circuit in harness between tumble generator valve position sensor and ECM connector.

CHECK POOR CONTACT.

Check poor contact in tumble generator valve position sensor connector.

Is there poor contact in tumble generator valve position sensor connector?

Yes

Repair the poor contact in tumble generator valve position sensor connector.

Replace the tumble generator valve position sensor.
