I need downstream bank 1 sensor, where is to go on vehicle?bfishingDec 21, 2023
Best Answer:Hi Brian, thank you for reaching out! It depends on the vehicle, but you can generally find a downstream sensor on the pipe after the catalytic converter. Have a good one!

Update need to take Chevy Impala to a dealership
I’m not quite sure as of yet.. I need to take this car now to a Chevrolet dealership to get their diagnostic for $156.00 to get down with its problem it’s having... so for now I’m keeping the two oxygen sensors and the oil pressure switch for now... this is awful but it’s what it is... I’ll keep you guys updated after I hear from the Chevrolet dealership test Thank You Vanessa 02/03/2021
