I just had a new Air/Fuel sensor put into my 2000 Accord. I'm about half way through my first tank of gas and I've noticed a huge drop in gas mileage. It's roughly a third lower. Is there some kind of break in period or should I take it back to the dealer who installed it?

Thanks!

Unless it was installed wrong, damaged or a piece for the wrong vehicle thats practically an impossible occurence. They arent meant to do that.

 

you have to go by mpg, how many mpg were you getting before and after.

 

Thanks for the replies.

My last tank before the new sensor gave me about 22.5 mpg. Based on my trip meter and fuel gauge right now I think I'm getting somewhere around 15.

 

clearing codes also clears adaptive fuel trim memory. Give it the tank and recheck on your next one.

 

this is the best way to check fill up no matter what level your tanks at to one click when pumping the gas, reset your trip gauge, then when you refill again divide the gallons you pumped into the car the second time by the miles on your trip gauge. so in other words

miles on trip gauge/#of gallons pumped in vehicle up to 1st click= miles per gallon
