OK,i keep getting the CEL and the code 1457 keeps coming up(munfacturer emmision controlled auxiliary emmissions controls) thats what it says on the scan tool. I search and only found one thread about this and it didnt go ito what could be causing this. I was wondering if someone could tell me what to check to see what is causing this. And the light keeps coming on when i start it in the morning and dont warm it up completetly and go.
1. Code 1457 keeps coming on
2. Want to know what are the possible things that could cause it
Just check that all the fittings are tight... they moved the evap cannister from under the hood in the integras to under the car by the fuel tank for the rsxs... I had the evap leak CEL come on and stay on all the time b/c road debris jumped up and nicked a hole in one of the rubber elbow connectors. So basically you have to jack up ur car and slide under there to check that all the hoses and connectors are ok.
ah i forget mention another possibility esp. the fact it only comes on when ur almost empty is that perhaps you just need a new gas cap... maybe its not sealing properly... also when u put on ur gas cap make sure it clicks at least 3 times.
its not your gas cap or else you would get code p1456 the code your getting is the charcoal canister check the lines running to it. It might only come on when 1/4 full because the gas is slashing more and making more fumes. Soooo then the charcoal canister is probably opening up to vent the fumes from the tank and the leak is somewhere in the charcoal canister or the lines running to it
if you are unable to find the leak you will have to take it to a shop that has a smoke machine for finding leaks in the evap system im not sure what it would cost to do that though.
hey in case anyone else gets this code, my problem was the valve on the evap canister i replaced it and the CEL never went back on it was like $42 from the dealer with my friends shops 20% discount :thumbsup:
thanx for the update, I wish more people would do this instead of making a thread and never returning. it's nice to do a search for a specific problem and actually finding the solution instead of starting another thread.
