Ok so i recently did an oil change with royal purple in my si and i took it for a spin and vtec worked just fine. I parked the car in the garage for 2weeks cuz i had to change the axle seals on the trans and when i was finished, i turned the key and a code 22 came up which is the vtec pressure valve. Ive heard stories about royal purple being too thin for some cars but the code is being thrown before the car is even turned on so i think it might be a different problem. I also read that if ur oil pan is damaged or dented then it could somehow cause a loss of oil pressure causing this code to be thrown.

So here are the possible causes of the code;
-Royal purple too thin
-Dented oil pan (dented it on accident when i supported the engine with a jack)
-Possibly just a bad wire connection?

Any other possible problems? I doubt its the actual valve cuz it worked like 2weeks before. But just to be safe, im gonna clean it with brake cleaner.

 

no help from anybody?
