Help me out here guys MAF

[paint94979]

My MAF is reading very low max of 4.05 lbs/min so that means my ECM will not add fuel or add timing. All fuses are good no nicks or gouges in the wires, I have changed MAF sensors no change. What also is throwing me for a loop is no codes? nothing? when the MAF sensor is not reference (tune) the truck runs normal. Anyone offer any ideas?

No ideas on how to fix it, but you could always drive without a MAF until you get it fixed..

That is the only way I was able to race in AZ other wise I was dead in the hole

Maybe swap in another ECM just to test it?

 

[paint94979]

So I just swapped in some older tuning for diagnostic purposes and I got it to throw a P0102(MAF Sensor Circuit Low) but what can I do? Anyone know the proper way to diagnose this issue?

I guess that is possible... I have had many failed flashes I dunno if that could effect an issue like this?

That's how its been running since phoenix but I would like to fix it because I'm also having an issue with my 12v aux plugs

12v aux plug how about the light does it work fine. It almost sounds like a grounding issue. Back trace all your wires and make sure no pins came loose. What did you do to the truck the last time before it stopped working right I would back trace your steps.

I cleaned my air filter (K&N oiled) and it started happening... I though maybe I got something wet but I have checked all the pins in the cam locks sprayed the shit out of them with contact cleaner, as well as the MAF plug and sensor. The 12v AUX thing has been going on for a while and was working in AZ for a bit... pretty stumped

Is the MAF pointed in the correct direction? Kinda dumb but I'm sure its been done before

it could very well be the opposite way... not sure if it effects anything?

 

[x MadMAX DIESEL]

Yes it would have a huge affect, if you look at one up close you will see why.

ill go swap it over

Well I'm pretty sure you can tell by looking at it, its been awhile. But I think if its wrong youll see the needle will be blocked off by some plastic.. Either way it will read horribly wrong.

I just might be that dumb? LOL i bought an ohm meter checked for bad grounds and found nothing... I never ever thought to check the sensor but yep you were right the sensor is encased in plastic wow, thanks for the suggestion

Have you checked to see if you have 12v on the pink wire at the maf?
