DTC P2017 INTAKE MANIFOLD RUNNER POSITION SENSOR / SWITCH CIRCUIT HIGH (BANK1)

DTC P2017 INTAKE MANIFOLD RUNNER POSITION SENSOR / SWITCH CIRCUIT HIGH (BANK1)

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 more than 4.9 V?

Yes


No

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

Turn the ignition switch to OFF.

Disconnect the connector from throttle position sensor.

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

Connector & terminal

(E54) No. 2 — Engine ground:

Is the resistance less than 5 Ω?

Yes


No

• 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 coupling connector

• Poor contact in joint connector



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

Turn the ignition switch to ON.

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

Connector & terminal

(E54) No. 3 (+) — Engine ground (−):

Is the voltage more than 4.9 V?

Yes

Repair the battery short circuit in harness between tumble generator valve position sensor and ECM connector. After repair, replace the ECM.


No

Replace the tumble generator valve position sensor.
