ok here it goes. my 2001 dakota was giving p442 and p455 codes. replaced purge selionoid and leak dection pump. codes came back. recently had to replace battery. light came back next day but not showing 442 and 455 it now has 161. is it possible the 161 code was causing the 442 and 455?

 

Probably not. Complete separate systems.

 

ok thanks. but the 442 and 455 were driving me nuts

 

Those evap system codes usually are a biotch to fix.....
