Re the P0113 code. I watched a short vid on the IAT - needed to ID its location. The tech pulled the sensor and remarked about how carboned up it was. Reminded me of all the sludge I saw in the intake when I pulled the EGR valve. No obvious puddle of coolant, but definitely moist sludge. Would that be the most likely cause of the code, a gunked up sensor? Of course, per my previous post, I'm not even sure of these remaining codes are "current." There's no CEL right now.

The P0406 - could that be the junked up EGR valve? I cleaned it up a few days ago but the code is still there. I recall using a screwdriver to pry the valve open. Don't recall whether I pushed it back closed. Shouldn't it close by itself? If it's sticking open would that throw the code?

I'm stumped on the 0683 for the GPM. The B1318 for low voltage - I originally thought this set when one of my battery terminals came loose on that trip. Engine died briefly, but restarted long enough for me to pull over and tighten it. Apparently not well enough, since it came off again yesterday when I pulled the battery tray out. Not sure now if it reset because my batteries are getting low, or if Torque just isn't clearing it. When I clear the codes, Torque goes through its process and returns a blank screen, so I assume it's clearing them and they're resetting.

Also don't know what the U2023 was, but it's not come back now.

 

I know I am a little late to this party.
When I needed a pigtail for a project and the one I wanted was not listed.
I used the images to match up what I was looking for and then used the
non-Ford part number to look on Ebay and Amazon. I found what I was
looking that way and paid a lot less than the Ford robbery price for them.

Also keep in mind that there are three types of major connectors.
Weather Pak
Deutsch
Amphenol

Mostly you will find the first two in out trucks.
As for testing you want to use what is called "Back Probing"
It is where you use a probe that is small and able to side into
the back side of the connector so you don't damage the pin and socket.

 

Thanks, Vis. I have Forscan on my PC, forget when I downloaded it and have never used it. Actually never connected anything to my PC via Bluetooth, but I'm going to try it. Will also see if it's available for Android.

 

IA1 is part of the MAS airflow sensor and IA2 is on the driver side of the manifold just about
where it starts to run straight after the bend from the front. It can indeed get all sludged up.
A deep socket and some carb cleaner is really all you need. Just put the straw on the can
and spray it clean. You don't want to do any picking at it at all.

 

Thanks, Sean. I think those codes cleared when I swapped in a different sensor, but I'll need that vid soon, I'm sure. And even if the codes cleared and the sensors are all working, those wires are all tore up so I'll be replacing the pigtails soon. Lots of bad wiring on this truck.

When I was pulling the sensor out of my other ambulance to use, it was obvious that someone rerouted the oil dipstick and fill tube on this bus??? I wondered why they were in the way. SMH. I also see the vacuum line that I found cut and stuffed out of the way on this truck. Not sure what it does though. It's on the driver's side and on the ambulance plugs into a larger hose above the brake fluid reservoir.

Someone should slap the fluid out of the tech that worked on this truck. I am getting a lot of the greasiness cleaned up in this process.

 

Forget why, but I'm thinking the code set from the manifold sensor. Are they both sensing temps? I guess the PCM is comparing the two? The one on the air box is in place and connected. There was a bunch of greasiness in the airbox. I got a can of MAF cleaner, maybe I'll spray it down too. Had to quit for the night since I'm working outside, but I'll pull that other sensor tomorrow and clean it off.

I know you have IDS, do you know if those Torque codes are actual or past codes stored? I need to do a lot of clean up on this truck - in due time, but don't need to be distracted from the main issues right now.

 

How about a list of the possible causes of the gray smoke? Or could that just be a symptom of whatever won't let the engine rev up? Last thing I want is to have to replace injectors on this PITA. Wondering if my problem is fuel pressure. Maybe I'll swap the pump over from my ambulance.

I know, I need a fuel pressure gauge.

 

Forscan Lite for Android and Apple phones is 4.99 or 5.99. Forgot exactly. Well worth it.

 

Just remember the "Late" 05's did away with the MAF sensor, so IAT1 was independent for that part of the 05 model year.

 

Just curious, I notice that my Eseries don't have the electrical connection to the air filter minder like the Fseries. I'm not even sure what that connection does, but how does the Eseries monitor the filter?

 

The El Cheapo two-cavity (found on quite a few Toyos, Nissans, etc) interchange with all sorts of Fords, might fit that ECT sensor (signal return, ref voltage). I just used one on a 80's F-Series windshield washer pump.............

Ford has a nasty habit of rolling its connector parts numbers frequently (case in point is the Powerstroke's AC low pressure switch). Just look at all those RIDICULOUS WPT numbers in their catalog for example -- many provide the identical function.

BTW -- can't believe what some of these internet goons / slugs are charging for connectors --- total rip offs. Most (if not all) get made in Mexico, China, etc for around 50 cents to $2 each in batch quantities. Then some "enterprising" internet "middle men" step on these (like drug dealers) 2-5 times charging people absurd mark ups.

 

Then if the Ford dealer happens to have or get them for you add 200% more to that price.

 

Yes, yes, and yes. That catalog had the same part number (longer number below the WPT number) for multiple parts. And I wouldn't be surprised if those middlemen never even touch them - they just have them drop-shipped from China. Why else charge $16 dollars to ship something that little and light UPS Ground with 10-day delivery - same delivery as the Chinese who ship for free and charge 1/3 the price?

Their only cost is the SEO to get themselves to the top of Google's search results.
