Default Check Engine Light Code P0457

Hi guys, my car keeps throwing a code P0457 and I looked it up, has something to do with the Gas Cap? I'm only hitting 5 to 7 psi. Initially, I thought it was the BCS, so I disconnected it from the turbo and no change. I see oil build up around the PCV T-line. I read that its normal for the PCV to have oil build up, but looking at my line seems like oil may be coming out of it.

Is the check engine light related to the PCV oil build up??

Search in this section. The code is not just for the gas cap and not sure why the hell you disconnected the BCS. Probably a loose vacuum line from the evap solenoid. Blue connector behind the alternator under the intake manifold.

When I found out I had a boost leak, I tested the BCS to see if it worked. I heard a clicking noise when I applyed voltage on the solenoid. I unplugged the BCS from the from the turbo to see if I would get back up to boost but I was still boosting 5 to 7psi. This leads me to believe my problem is on the engine side.

On Monday while driving to work my check engine light came on. When I pulled the code it was P0457. According to my research code P0457 means Evaporative Emissions Control System.

Thanks for the link, I will inspect these locations and see if I can find additional problems on these hoses.

I had this exact problem 2 weeks ago, and this random T-fitting had just decided to come apart. reconnected and cleared no problems since.

Yesterday, I checked the hoses behind the alternator, looking at the blue nozzle. It looked like it was unplugged. According to the article above (see link) this blue nozzle should be connected?? When I turned the car on, I didn't notice any vacuum or leak coming from the nozzle. I didn't see any loose hoses around it. I will look again. Keep you guys posted.

Hi guys, just wanted to confirm, are there only two hoses connected to the blue T-fitting or three? I found that middle nozzle on the blue T-fitting was not hooked up to a hose.
I searched the boards, didn't get a clear answer. Thanks

Hi guys, anybody know what the part# is for the blue T nozzle? I dropped the T nozzle in my engine bay and can't find it now.
