I'm getting code p0113. Can somebody tell me if the IAT is part of the MAF assembly? I can't seem to find it.

 

My alldata doesn't cover 2010, find below diagrams for a 2008:






1) Remove the electrical connector and check for any damage wiring, then use 91% isopropyl alcohol and clean the 6-pin connector (both ends male and female)
2) If you have a scanner or obd2 adapter that can read livedata look for IAT value in cold start and see if anything looks odd
3) Follow pinpoint test DA
4) Don't waste your time and money buying a MAF cleaner as it's for routine cleaning only, it can't rescue and fix a bad MAF.
5) If you need to buy a new sensor don't go cheap, buy Motorcraft AFLS131 at rockauto if that's the right one, coupon code: 318043252281634034 and ship to a commercial address for lower shipping rate.

 

Thanks, great information. I'll get to it this weekend. I also realized that my 2013 Transit Connect uses the same drivetrain and I'm going to try swapping the MAF/IAT from that to be sure I'm chasing the right problem (p0113).

 

Be careful, all MAF sensors are not the same !

 

RockAuto shows the exact same Motorcraft AFLS131 for 2013 Transit Connect so you can swap it over, and you can even disconnect it then check the live data and do the comparison.

 

I hear THAT! It's my son's Focus. He works at AutoZone and has tried 4 MAF's from the store (BEFORE telling me it wasn't running right) and none of them fixed the problem.
I told him to only use OEM parts, and when we saw the dealer and online prices I decided to try the swap first so we were sure the MAF/IAT sensor was causing the troubles.

 

I saw that too. That's why I thought to try the swap first before spending well over $100 and it still not be right. Electronic parts are often hard to return.
