Q: My 2000 ford expedition is showing 0171 and 0174 codes do you have a estimate to fix?

asked by on August 22, 2016

Would not pass test

My car has 210000 miles.
My car has an automatic transmission.

The codes P0171 and P0174 point to a lean condition picked up by the oxygen sensors in the vehicle’s exhaust system. Since there is a warning from both banks, it may be safe to say that this is could be due to a vacuum leak. The leak may be in the area of the intake manifold or throttle body. Have a certified technician diagnose the cause of the Check Engine Light codes thoroughly in order to get a more clear estimate on the cost for repair.
