DTC P2017 - Intake Manifold Runner Position Sensor / Switch Circuit High (Bank 1)

DESCRIPTION
HINT: This IMRV position sensor is non-contact type.

The IMRV position sensor is mounted on the valve shaft axis P2004 and is used to measure the opening angle of the IMRV. Since this sensor is electronically controlled with hall elements, accurate control and reliability can be obtained.
Voltage of approximately 0.6 V is applied to terminal IACA of the ECM when the IMRV is fully closed. The voltage applied to terminal IACA increases in proportion to the IMRV opening angle, approximately 3.6 V is applied to the terminal when it is fully opened.
The ECM detects a malfunction in the IMRV position sensor when its voltage output deviates from the standard range. When a malfunction is detected, the ECM fully opens the IMRV using the IMRV motor until the IMRV position sensor returns to normal.
The related DTCs are P2004 and P2006 P2004, and P2009 and P2010 P2009.

INSPECTION PROCEDURE
HINT: - If different DTCs that are related to a different system are output simultaneously while terminal E2 is used as a ground terminal, terminal E2 may be open.

PROCEDURE

1. CHECK HARNESS AND CONNECTOR (ECM - IMRV)




(a) Disconnect the C33 IMRV connector.
(b) Disconnect the C24 ECM connector.
(c) Measure the resistance between the terminals of the wire harness side connectors.
Standard resistance (Check for open):






Standard resistance (Check for short):





(d) Reconnect the connectors.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
2. INSPECT ECM (VC VOLTAGE)




(a) Disconnect the C33 IMRV connector.
(b) Turn the ignition switch to the ON position.
(c) Measure the voltage.
Standard voltage:






NG -- REPLACE ECM
OK -- Continue to next step.
3. REPLACE INTAKE MANIFOLD RUNNER VALVE ASSEMBLY
NEXT -- Continue to next step.
4. CHECK WHETHER DTC OUTPUT RECURS
(a) Clear the DTC DTC Check / Clear.
(b) Start the engine.
(c) Run the engine at more than 3,000 rpm.
(d) Turn the ignition switch off.
HINT: As running the engine to 3,000 rpm, the IMRV usually becomes fully opened. If the ignition switch is turned off under this condition, the IMRV is fully closed and then becomes half-opening angle.
(e) Turn the ignition switch to the ON position 20 seconds later.
(f) Read the DTCs.
Result:






B -- SYSTEM OK
A -- REPLACE ECM
