engine lights been on for a few days these came up at the parts store what ?

 

The C, U and B codes shouldn't set the engine light, but that P0442 will.

A higher tech scanner could see if those other codes are just history codes or are actually thrown codes from the BCM functions/climate control etc etc.

P0442 means small evap leak. Might from a loose gas cap, or bad seal on the gas cap or a small leak somewhere else.

 

auto zone said its a ( evap )purge valve solinoid...part cost 34.00 he told me the lucas gas treatment might make it go away?

 

Gas treatment isnt going to make an evap leak go away... P0442 is "usually" caused by a bad seal on the gas cap or a small pin hole in an evap line somewhere...

 

C0305 is rear speed sensor code. And i think the c0355 is a code for park switch....
