Hello All,
I ve been changing everything on my max attempting to get another 100,000 miles out of her. I ma currently at 200,500. Changed sensors relating to DTC codes but I can not find the sensor for P1273 code. (Air Fuel Sensor). All help would be greatly appreciated also any places with good prices too.
Before I get blasted I did check the search icon about the locatoion and how to change before posting.
Thank you,
Blake

Bank 1 looks like the firewall side and Bank 2 looks like radiator side -- there's probably 2 sensors in each bank so you'll have to find the right one

Easiest way to remove this sensor is to remove the intake manifold plenum. If you have not replaced spark plugs yet, use this opportunity to change them.
