Check engine light came on today
So I finally got the code reader I ordered from Walmart.com, read the codes and got a P0449 code (EVAP vent solenoid control circuit malfunction) and a P0455 code (EVAP system gross leak detected).
Has anybody else ever had these codes come up on their Monte? What needs to be done to fix the problems?

Here's a good site for info on codes: OBD-II Check Engine Light Trouble Codes.
From reading posts on chevroletforum.com about the P0449 code, it looks like it's usually caused by either a defective EVAP vent valve or the EVAP vent solenoid.
YES! The same 2 codes came up on my 2001.
P0445 happened. I took off the small EVAP thing under car up by gas cap and installed new one from Auto Parts store. Bought new GAS CAP too. That was a NO NO !! The p0445 came back so I replaced the EVAP thing on the front of the engine. Now! I got the P0449 code. Hmm picked up code reader/rest. Cleared and still P0449. went to GM $37.00. Let me know if ya need more specifics
