Okay, Im not new to this site, but I really cant navigate myselt to the code section, if there is any. Im kind of in a bind, so if someone knows where to direct me please do. I would really appreciate any answers. So yesterday I installed MREV2 and ISO spacer along with an Injen intake. Mods work great, great sound, no air leaks, couldnt be happier. But now Im throwing a service engine light. My buddy read the code, but doesnt know what it means. The code is Either OP444 or PO444. If anyone has any answers please respond.

Thanks,
Josh

 

P0444 EVAP Canister Purge Volume Control Solenoid Valve

 

Thank you DR. for the code. I took it to autozone and he could read me the code, but didnt know what it was. Im going to assume it has to do with an emisions sensor. Another thing I didnt say was that I had to cut into my coolant line to put in a control valve. I dont think it has to do with it, but it could. Has anyone else had a check engine light from this stuff?

 

Okay, so I found out what it was. Just so people know. Your EVAP Canister Purge Volume Control Solenoid Valve which is code PO444 is the solenoid on the back left side of your upper plenum. It has 2 hoses run to it and a plug. I forgot to plug that back in, which in turn tripped the Check engine light. It has to do with releasing Hydrocarbons. BLAH BLAH BLAH.
