sdc Posted March 9, 2010 Share Posted March 9, 2010 I have a 2003 Land Cruiser which today brought on the check engine, VSC Trac and VSC Trac Off lights. I went to a local parts store to pull the codes: P0441 & P0446, evaporative emission control system incorrect purge flow (P0441); and evaporative control system vent control circuit fault (P0446). They asked if I topped off while filling up, which I can't say that I do (although I have in the past but not frequent enough to warrant this). They also suggested tightening the gas cap more thuroughly. It might be worth mentioning I just had all four rotors and pads replaced less than two weeks ago. I did read a few posts online about these three lights and low master cylinder brake fluid levels. Any suggestions would be appreciated. Link to comment Share on other sites More sharing options...
Leighcm Posted March 10, 2010 Share Posted March 10, 2010 It's the gas cap 90% of the time...just make sure you tighten it a couple clicks when you close it so the pressure is right. Link to comment Share on other sites More sharing options...

What about resetting the lights? Pull off the negative terminal for a couple of minutes to reset? Or what? Link to comment Share on other sites More sharing options...
Leighcm Posted March 11, 2010 Share Posted March 11, 2010 It usually resets by itself once the pressure is back to the appropriate level, assuming that the gas cap is the issue. Link to comment Share on other sites More sharing options...
