    Smile Toyota Highlander VSC & check engine light

    THanks to this forum I probably saved myself lots of money and a headache. I recently purchaced a 2002 toyota highlander and had only had it for a few wks before the VSC and check engine light came on. I took it to Advanced Auto and had it hooked up to a battery which read 3 codes-P0440, P0441, and P0446. These were evap emissions codes and I was told I needed a canister purge valve and vapor canister, splenoids which would cost around $300.00. I wasnt very happy and decided to check on the internet when I came to this site. Someone else had the same problem and said the lights were coming on because the hose on the air filter box was loose. I immediately went outside and sure enough they were right! I reattachced the hose and had the light turned off and it hasnt come back on since! One more thing does anyone know why the airbag light flashes on and off when its really cold out? Thanks again!

    I'm glad you were able to get that problem figured out. That happened to me, and it was a headache for a while there. Unfortunately there aren't too many resources for highlander owners on the web, so I am sticking to this place and hoping other active members will follow.

    As far as the airbag light goes, how cold are we talking here. I have a '03 and live in Colorado. This year it has gotten fairly cold (-20f at night), and I have never see mine come on. There may be something wrong with yours. Has it ever been in a wreck.... enough to set off the air bag. I just wonder if it wasn't repacked properly, or replaced, or whatever it is they do. That's the only thing I could think of.

    I have a 2002 also, and have seen the air bag light flash in cold weather (10-20 deg F). This goes away as soon as it gets warmer, or as the vehicle warms up. Maybe the compressor does not do well in the cold, or it could be the sensor.

    My Haynes Repair Manual states that there is a fault in the airbag system if it stays on, flash or dash makes a beep and should be taken to your dealer. Hope that helps!
