sakr4360 Posted April 9, 2008 Share Posted April 9, 2008 So while driving the 99 es300 yesterday the VSC and check engine lights come on. I checked various vac lines and the gas cap and all seems in order. I had it scanned at Advance Auto parts and the following codes were read. DTC codes P0441 Evap emissions Control System Purge flow Fault P0446 Evap emissions Control System Vent Circuit Malfunction Help !! Any recommendations where to start looking? Thanks guys.

sakr4360 Posted April 15, 2008 Author Share Posted April 15, 2008 Fixed. Looks like the gas cap was not tight enough and the code was set. I pulled the EFI fuse for a half hour and all is well. Quote Link to comment Share on other sites More sharing options...
