Question about 1999 Ford Windstar

1999 ford Windstar

The service engine light came on my Ford Windstar 1999. The mechanic checked it on his computer and came up with a Code PO 171.
I changed the oil and filter and now the light has gone off, but I want to find out what that code stands for. Would the oil change and filter make that much difference. It does not chug-chug and it has power again.

That code is the maf sensor I had the same problem but it went away like yours did only to return a month later. When I was looking this up it seems this is a problem with the winstar

Getting codes po171, p0174 and p0128


Code 171 is fuel system too lean bank one, and 174 is the same for bank two. Usually a vac leak or low fuel pressure.
Code 128 is for the engine not reaching normal operating temp. Usually a thermostat problem.

2002 ford windstar engine lean bank 1 and lean bank 2


Google your codes & then diagnose the
system & items related to the codes

Type: OBD Code PO 171 --or whatever the codes are

If you have Oxygen Sensor Codes, it is most likely the upstream sensors have failed, because you did not know they get replaced as preventative maintenance at 100,000 or when they fail, if that is how you take car of your vehicles

Hi,i have an windstar engine code 171 and i dont know whats the problem


171 is the 1st bank running lean. If you have the 3.8 motor, I am pretty sure it is the beginning of the leaks that cause the 174 code (other side) gaskets and seals to fail. Ford has never been able to make the 3.8 motor work! The good news is they are aware of it and have a service bulletin out on it. It probably will cost between 6-8 hundred, again assuming you have the 3.8 Save your receipt, maybe one day Ford will own up to their mistakes on the 3.8 and if they do a recall they will reimburse you.

Po171 error code


P0171 means the system is lean on cylinder bank number one, with just the one code you could replace the bank one upstream O2 sensor and that will most likely cure the problem.

ford has a technical service bullitin out on this vehicle for the intake gaskets leaking causing a vacum leak that set codes 171 174. the solution is to have the intake manifold gaskets replaced . call your local ford dealer and see what thay can tell you about this bullitin.

PO 171 and PO174 codes but different problem


transmision shifts are based on engine load imputs a 171 and 174 refer to a lean condition therefor the shift is being based on an assumed cold engine so yes it may be related
