Hi there:I suggest to check on the Power Distribution Box, that is located in the engine compartment.The power distribution box contains high-current fuses that protect your vehicle's main electrical systems from overloads. A code P0171 may mean that one or more of the following has happened:
DTC P0171 - System Too Lean (Bank 1)This DTC is very similar to P0174, and in fact your vehicle may show both codes at the same time.
Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
Possible solutions, a lot of times, cleaning the MAF sensor and finding/fixing vacuum leaks fix the problem. If you're on a tight budget, start there, but that may not be the fix for certain. So, possible solutions include:
