I have an 01 Sienna I am selling and it has the check engine light on. The van seemed to run fine, so I took it to a mechanic a couple of years ago and he said that it was an emission issue, but if it didn't start running bad it wouldn't hurt to drive it like that. The light has been on for a year or two, but I'm getting ready to sell the van and I want to get the light to go off. Is it possible that it could be an 02 sensor if its throwing both a 171 in bank 1 and a 174 in bank 2 or would that mean that there is an issue causing both sensors to read bad? what is the cheapest thing I can do to try to get the check engine light off, and have it stay off?
