I got error code 0704--'EVAP control system pressure sensor" What the hell is that? Is it expensive? Is it bad for me to drive my car? and also my rear O2 sensor keeps going off, it's only 2 months old. Why does it keep going off every once in a while? thanks.

I had code 0704 and 0215, the 0215 being the EVAP CV control valve.. Also, my fuel filter was clogged so my car didnt get enough fuel at startup( I dunno if this was related)..

So, I replaced the fuel filter.. Then I found the CV control valve, greased it with WD40, and put it back on.. Now the car starts fine and the CEL is gone..

THANKS! I'll try greasing it up. I know my fuel filter is fine cause I just put a new BOSCH one in about a month ago. Time to go grease that **** up.

You also may want to make sure that you have your gas cap on tight. The actual EVAP canister is located slightly behind your right rear tire and can be removed simply. You could have several things happening. Do a search for 0704 and you will find the information you need.

Good luck!
