Small evap leak detected

[the davis]

My 02 Montero keeps throwing the small evap leak code (0442). I have changed gas cap with mitsubishi cap, replaced gas tank and seals due to a recall. The dealer recently ran a smoke test and can't find a leak, this test has been run four times. The purge valve has also been replaced and I am still getting the code. Is there a way to bypass the sensor or does anyone have any other ideas about what might be causing the error? Thanks for the help!

Have you checked the sensor?

Have you checked the sensor?

The sensor has not been checked! Does anyone know where the sensor is located? Is there a test for it or should i just replace it? Thanks

You will be able to find that information in the factory service manual. It's on this website in 2 parts, download both.

This happened to me. Eventually I traced it to corroded vent lines from the fuel spout assembly under a plastic guard on in the rear passenger side wheel well. The parts were expensive but I was able to hack saw off the corroded line sections and replace them with rubber smog hose and I have had no more problems. I guess the rock guard in the wheel well traps all this wet slime and silt and the over time corrodes the steel lines.
