DTC P2089 INTAKE CAMSHAFT POSITION ACTUATOR CONTROL CIRCUIT HIGH (BANK 1) - DIAGNOSTIC PROCEDURE

Step	Check	Yes	No
1 CHECK HARNESS BETWEEN ECM AND OIL FLOW CONTROL SOLENOID VALVE. Turn the ignition switch to OFF. Disconnect the connectors from ECM and oil flow control solenoid valve. Measure the resistance between oil flow control solenoid valve and engine ground. Connector & terminal (E67) No. 1 - Engine ground: (E67) No. 2 - Engine ground:	Is the resistance more than 1 MΩ	Go to step 2.	Repair the short circuit between ECM and oil flow control solenoid valve connector.
2 CHECK OIL FLOW CONTROL SOLENOID VALVE. Remove the oil flow control solenoid valve connector. Measure the resistance between oil flow control solenoid valve terminals. Terminals No. 1 - No. 2:	Is the resistance between 6 and 12 Ω?	Repair the poor contact of ECM and oil flow control solenoid valve.	Replace the oil flow control solenoid valve. < Ref. to OIL FLOW CONTROL SOLENOID VALVE . >
