The IVTC solenoid valve changes the amount of oil and direction of flow through IVTC unit or stops flow. The longer the pulse width the more valve angle advances. Shorter pulse width retards valve angle. When on and off pulse widths become equal, solenoid valve stops oil pressure flow, and intake valve angle is fixed at control position.<\/p>\n<h4>Intake Control Valve Control Solenoid Testing<\/h4>\n<ol>\n<li style=\"list-style-type: none;\">\n<ol>\n<li>Turn ignition off. Disconnect IVTC solenoid valve 2-pin connector. Turn ignition on. Measure the voltage between ground and IVTC solenoid valve harness connector terminal No. 1 (Red wire). If battery voltage does not exist, go to next step. If battery voltage exists, go to step 3.<\/li>\n<li>Check the following:\n<ul>\n<li>Harness connectors E1 and M1.<\/li>\n<li>Harness connectors M33 and F22.<\/li>\n<li>Check Harness continuity between IVTC solenoid valve and ECM relay.<\/li>\n<\/ul>\n<p>Repair harness or connectors.<\/li>\n<li>Turn ignition off. Disconnect ECM 116-pin harness connector. Check continuity of Orange\/Black wire between Bank 1 IVTC solenoid valve harness connector terminal No. 2 and ECM harness connector terminal No.11, or Pink\/Blue wire between Bank 2 IVTC solenoid valve harness terminal N0. 2 and ECM harness connector terminal No. 10. Also check circuit for short to ground and short to voltage. If problem is found, repair as necessary. After repair, repeat DTC confirmation test. If no problem is found, go to next step.<\/li>\n<li>Measure resistance between IVTC solenoid valve terminal No. 1 and 2 (component side). Resistance should be 7.0 &#8211; 7.7 ohms at 68 degrees F. Check continuity between ground and IVTC solenoid valve terminal one at a time. Continuity should not exist. If resistance and continuity are as specified, go to next step. If resistance or continuity is not specified, replace IVTC solenoid valve and retest system. After repair, repeat DTC confirmation test.<\/li>\n<li>No problem is indicated at this time. Problem may be intermittent.<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-55083\" src=\"https:\/\/www.freeautomechanic.com\/mechanic\/forum\/wp-content\/uploads\/2018\/02\/2003-nissan-pathfinder-ivtc.gif\" alt=\"intake timng control valve\" width=\"971\" height=\"643\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>I need to know how to test the intake valve timing control solenoid.
