SOURCE: Cleaning the Mass Air Flow Sensor

i will try to help. 171/174 indicates lean condition in engine. the mass air flow sensor is located in the rubber tube going to throttlebody. you can try to clean it. using mild carb cleaner safe for sensors, remove sensor from tube. spray clean the tiny wires located in the cylinder. do not touch them, they are very delicate. these engines are also notorious for leaking intake gaskets and faulty pcv valves. these will all set these 2 codes. feel free with anymore questions.

SOURCE: I have a 2004 freestar

I just had the same thing. Engine light came on. Rough idle. Codes P0171, P0174, P2195, P2197. Within a week the idle got so bad it would die at stop lights. Seemed like a vacuum leak affecting the idle. Found it today. The elbow where the PCV tube enters the vacuum port on the upper intake was degraded, collapsed and had a whole in it. Wondered why it degraded. I disconnected the tube from the PCV valve and found it quite oily. I think the oil sat in the elbow at the intake because it is flat on top of the engine and could pool there, causing the rubber to degrad. Found a preformed piece of coolant hose at O'Reilly that was the right diameter and cut it to length. Put it on, runs like a charm. I ordered a new PCV valve because I think too much oil was coming through it and caused the hose failure._409.jpg_410.jpg

P0171 and P0174 for 2004 ford freestar ..Van running fine , even after erasing same codes comes back Is it O2 sensor or MAF sensor


Clearing codes is just removing ALL Data

That doesn't do anything more than that

It is not a fix for anything

Type: OBD PO171 & read up on oxygen sensor codes

All vehicle problems & solutions, are are over the internet

All codes are there also, if you know what to type or ask

You need to replace all front oxygen sensors,on all vehicles,
at 100,000 miles

That is preventative maintenance that is not in your owners manual

You learn the hard way, after things fail & continue on, more knowledgeable & proactive in the future

Ford error code p0171 and p0174


You should have replaced the upstream oxygen sensors
at 100,000 miles before they failed

The ignition misfire is a separate problem you have to solve

All that free checking is a waste of time

Go to a local non franchise honest repair shop & have the
vehicle properly repaired

Got code P2195, P2197, P0171, P0174??


  • There are some clips on the back of the engine by the manifold that break real easy. In fact there is a TSB about them. These clips hold the IMRC linkage rods to the runner shafts. When they break the linkage will just hang there.
  • See diagram

  • These are a dealer only item. Replace them and this should fix your problem.
  • Hope this helps and thank you for using FixYa.
