Oil Control Valve Operation

Remove Oil Control Valve (OCV) to be tested. Connect a fused jumper wire between battery voltage and terminal No. 1 at OCV. See Fig 1. Connect another jumper wire between negative battery terminal and terminal No. 2 at OCV and note OCV plunger operation. With battery voltage applied, plunger on end of OCV should extend. Disconnect a jumper wire. Without battery voltage applied, plunger should retract. If OCV operation is not as specified, replace OCV.
