i got code 54, 31, 85

31 and 85 have been there for months, just EGR bull****.

code 54 is the new code its weird, the book says

"Vane air flow sensor or air charge temperature sensor"

straight from the haynes manual, i didnt know we had air charge temp sensors in the 5.0s. whats this mean?
it's either the MAF sensor OR the air temperature sensor built into the same housing with the MAF (vane air sensor). that what the code 54 is telling you to check out. probably got oil from the air filter on the wires in the MAF and this is making it act up on you.


thanks roundman, how do i clean this? the MAF is such a delicate device.

To clean the MAF just get a can of carb cleaner or brake clean but make sure the can says "no residue" on it. Take your MAF off and spray down the tube on the little wires and allow to dry then re-install.

I cleaned the maf thoroughly with a Qtip and made sure it was sterile. i ran the car to school and the gas mileage got much better, i think back to normal. but i still noticed a drop in power and the engine running a little warmer than usual... dont know whats up with that.

The Air Charge Temperature sensor or ACT is located on the lower manifold on the drivers side towards the front of the motor. If its reading the air temp in the manifold incorectly it will cause rich condition, and driveability problems.

the manifold i got had no fitting for the ACT. so i left it unplugged, its been that way for a month with no change in gas mileage except for just recently. when i looked at the sensor it was really crummy and had lots of buildup, so it probably never worked anyway.

My ACT was installed in the intake tube right before the throttle body as I have the explorer upper and lower without provisions for the ACT. I replaced mine as it looked the same way you described, mine fixed the hanging throttle issue I was having.

ahh, so where exactly did you place the ACT. between the MAF and TB. and did you drill a hole in your CAI and just screw the sensor in there? but wouldnt the air charge temperature differ from where that TB is to where the lower intake manifold is (where the ACT should be)... and yes i have a explorer intake too. any ideas?

Here is a pic of where my ACT is exactly,

As far as does it make a difference in engine performance? They did dyno test with it in both places, some say it is better in the CAI tube as it gets a better gauge of actual air temp instead of air temp from a heat soaked manifold. And yet others maintain that it is better in the intake. To my understanding Ford moved it to the air filter box in 94 so there must be something to the air intake track, rather than the manifold.

Forgot to add, I used a rubber valve cover grommet to insert the ACT into, as the hole came out a little bigger than the ACT itself. This makes it easier to remove if you have the need, its a nice tight fit and screws into place but I don't have to worry about it seizing or anything like that. I did run a bead of clear RTV silicone around it as well because I'm over cautious like that lol.

thanks for the info birdman, how did you extend the wiring to that area though? just cut it out of the harness and pull.. lol the old fashioned way...

thanks for the info though dude.
