Re: Check engine light (EVP LEAK)

["Jack Terzian" <jack_terzian@howling.com>]

Mine did this...

After someone swiped my gas cap....

drove for about a day then check eng. light turn on....

The dealer said check the cap....  I did and it was missing... I replaced
it.... then took it to the dealer for the code to be removed....

The OBDII senses that there is a leak in the fuel system. then default mode
begins (sensors turn off)   This is because the engine is having problems
keeping the pressure in the fuel line up and there is vacuum leak in the
system ( So I understand....)

Moral -----  Not good but not bad.... OBDII too smart

Hope this helped,
