Hello everyone,

Been working on getting this engine to work right. Recently moved to a colder climate and once it was up here the Vtec decided it wasn't going to kick on anymore. I took off the solenoid thinking it was a oil pressure drop but the gasket looks brand new and oil is flowing through it. The ECM has given me problem in the past when it would trigger into a "Fail-safe". So I was wondering if the ECM would also be controlling that solenoid or not? Maybe the solenoid is seized now? Not sure what to make of it...

 

The ecm does control the vtec. It could be the solenoid or the vtec pressure switch or a ground problem. If you search this site you will find several excellent threads on how to trouble shoot it.
