What should I do if I get a p0171 code?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded terminals. If the P0171 is combined with the P0174 code, it’s very likely that the problem is caused by an intake leak.
Why does my Ford Windstar have a p0171 code?
If the P0171 is combined with the P0174 code, it’s very likely that the problem is caused by an intake leak. If there are no intake leaks, the next step is to replace the air filter and clean the air flow meter. If the problem persistss the front oxygen (O2) sensor may need to be replaced. It’s a very common problem for the Ford Windstar.

Why is my MAF sensor sending out a p0171 code?
How to Fix P0171 and P0174 While inspecting the intake boot thoroughly, another option is to stop at the MAF sensor itself. MAF sensors can get dirty or oiled and send out a false signal, but usually this is also indicated by a MAF trouble code as well.

When does the front O2 sensor Register p0171?
P0171 is triggered when the front O2 sensors recognize a lean mixture. It can both be a short-term lean mixture or a long-term lean mixture. If it’s a short-term lean mixture the fuel mixture is often very lean. If it’s a long-term mixture, it can register the code because of a small notice of lean mixture over time.
