SOURCE: 08 Impala - Check engine lite on - Large Evap leak detected

If it is missing or not running perfectly you can damage the Oxygen sensors or the catalytic converter. If it is running perfectly then more than likely no damage will be done, but you still need to have it looked at by a professional with the proper tools and skill to diagnosis the problem and not just throw parts at it. The PCM and catalytic converter are covered by an 8 year 80,000 mile warranty whichever comes first. To know if your defect is covered which is highly unlikely, you need to talk to your local GM dealer.

Why is my 2010 ford fusion is throwing code po455. no gas cap required


P0455 is Evaporative Emissions System Leak Detected (Large) and means that there is a large leak in the system probably with one of the EVAP hoses near the fuel tank or EVAP canister or maybe even A leaky purge valve.

I am getting a po442 code on my scan tool. A small evap. leak detected. I have replaced the gas cap a couple of years ago. I put the lite out and it stays off for about a year then comes back on. Anybody...


This is what they call a 2 trip code. It takes two running times to set. Small leak is 98 % of the time gas cap not on tight enough. Three clicks minimum. Just reset the computer and see if it comes up again. For your year EVAP is not a big deal. Doesn't hurt fuel economy or performance.
