CSVT_Tessa Posted May 14, 2014 Share Posted May 14, 2014 P0171 system to lean P0455 Evaporative Emission Control System Leak (gross leak) I feel like they may be related? No power loss or leaks. Any advice would be appreciated! Satya Link to comment Share on other sites More sharing options...
Terry Haines Posted May 14, 2014 Share Posted May 14, 2014 ..P0455 could be the gas tank cap seal or one of the rubber lines at the back from the evap cans or at the front where the purge sol is located.. Link to comment Share on other sites More sharing options...
CSVT_Tessa Posted May 14, 2014 Author Share Posted May 14, 2014 "evap cans or at the front where the purge sol is located " I dont know what that is? or what it does? I'll clearly start by replacing the gas cap first tho... Link to comment Share on other sites More sharing options...
CSVT_Tessa Posted May 14, 2014 Author Share Posted May 14, 2014 ok read up on what it does.. but is it that black canister thats on the back of the UIM. Not sure about the location under spair tire. Link to comment Share on other sites More sharing options...
Terry Haines Posted May 15, 2014 Share Posted May 15, 2014 ...looking under the hood..at the l/h side of firewall..just down and behind the a/c charge point is the plastic purge sol..it opens to allow gas fumes from can at back under spare wheel well to bleed fumes into the intake manifold via the top of the pcv valve...any leak in the lines from can to purge sol and from purge sol to pcv connection could trigger a code .
