Question

i have 2001 dodge durango 4.7 eng upstream and downstrean 02 sensors code was po171 on my car how sensors do i have?

Answer 1

what other codes do you have?

P0171 and other oxygen sensor codes could mean an intake leak that will have to be checked first 

there is either 3 or 4 sensors depending on how your exhaust looks 

P0171 is for bank 1 sensor 1 if the oxygen sensor is bad.

it is on the driver side before the catalytic converter
