p1259 vtec system malfunction

No. I just took it apart to change the filter. Then put it back together. The old filter seen to be clean but I still change it. I will be cleaning the switch pressure soon. Im trying to find all the solution posible. Thankz a lot for the help. One last question is the plunger the switch pressure?

The plunger is the part under #15 with no number. Just to verify, you aren't talking about the oil filter, are you?

I'm talking about the screen filter, #13. See that black part on the gasket? That's a little screen.
