Hi,
The check engine light came on in my 2001 Odyssey. The first time it came on shortly after the 2 gallon gas warning light came on. The light stayed on for a while until I gassed up. This has happened several times. Today the check engine light came on after my wife gassed up the van.
I have a code reader here so I checked for the codes. The codes are p1491 and po420. I figure these codes are related... 1 problem is causing both codes. Any ideas out there what the problem could be? Otherwise the van runs ok... no hesitation or anything.
Thanks for your time,
Brad
