Question about 2000 Chevrolet Tracker
HI, with a DTC PO440 you are looking for a very small leak without the proper test equipment they can very hard to find since the EVAP lines are small and routed up and over things. Here are a few of the common problems i fix for this DTC on Trackers. Chcek the lines running into the purge tank they crack. check the top of the fuel filler neck for rust it doesn't let the car seat and seal. If you cant find anything by visual inspection you will need to go visit your favorite mechanic.
