ENGINE (DIAGNOSTICS)(H4DO) > Diagnostic Procedure with Diagnostic Trouble Code (DTC)

DTC P2093 INTAKE CAMSHAFT POSITION ACTUATOR CONTROL CIRCUIT HIGH (BANK 2)

DTC DETECTING CONDITION:

Immediately at fault recognition

TROUBLE SYMPTOM:

Improper idling

CAUTION:

After repairing or replacing the defective part, perform the Clear Memory Mode and Inspection Mode .

WIRING DIAGRAM:

STEP	CHECK	YES	NO
1.CHECK VOLTAGE OF OIL FLOW CONTROL SOLENOID VALVE. 1) Turn the ignition switch to OFF. 2) Disconnect the oil flow control solenoid valve connector. 3) Measure the voltage between oil flow control solenoid valve connector and engine ground. Connector & terminal (E70) No. 1 (+) — Engine ground (−):	Is the voltage 10 V or more?		Repair the open circuit of harness between the oil flow control solenoid valve and main relay.
2.CHECK HARNESS BETWEEN ECM AND OIL FLOW CONTROL SOLENOID VALVE. 1) Turn the ignition switch to OFF. 2) Disconnect the connectors from ECM and oil flow control solenoid valve. 3) Measure the resistance between ECM and engine ground. Connector & terminal (E70) No. 2 — Engine ground:	Is the resistance 1 MΩ or more?		Repair the short circuit between ECM and oil flow control solenoid valve connector.
3.CHECK OIL FLOW CONTROL SOLENOID VALVE. 1) Disconnect the oil flow control solenoid valve connector. 2) Measure the resistance between oil flow control solenoid valve terminals. Terminals No. 1 — No. 2:	Is the resistance between 6 — 12 Ω?	Repair the poor contact of ECM and oil flow control solenoid valve.	Replace the oil flow control solenoid valve.
