Question about 1996 Ford Windstar
I have a 1996 Ford Windstar, 128k miles, 3.8 engine. I am getting a total of 4 codes as follows: No. 1 - P0171 (freeze frame), System to Lean, Bank 1; No. 2- P0141, 02 Heater Circuit, Bank 1, Sensor 2; No. 3- P0161, 02 Heater Circuit, Bank 2, Sensor 2; and No. 4 - P0174, System to Lean. Could these 4 codes all be related to the same problem? If so, what could the possible solutions be? Also, where is the Bank 1, Sensor 2 and the Bank 2, Sensor 2 Oxygen Sensors located? Also, which set of cylinders is the Bank 1 set? Thanks
Mass Air Flow sensor. All four o2 sensor are not going to fail at once.
I went through this for weeks trying to figure it out. I had just replaced the MAF sensor about 8 months prior, so I thought it must be something else. After throwing new intake gaskets and o2 sensors and fuel pressure tests and compression tests and smoking the intake, I discovered that the MAF sensor had failed. Truck runs great to this day. BTW, NEVER EVER use MAF sensor cleaner from an aerosol can on a MAF sensor, and o2 sensors do not need to be cleaned, they live in soot every day and they like it that way. They usually outlive the vehicle except in cases of over-adding STP type cleaners and using bad gas. They should only be removed when your catalytic converters finally burn out. (My opinion)

System Too Lean (Bank 2)
Basically this means that an oxygen sensor in bank 2 detected a lean condition (too much oxygen in the exhaust.
Note: This DTC is very similar to P0171, and in fact your vehicle may show both codes at the same time.
