Thank you WAVESINE for this detailed and critical information. i could have spent countless visits to the dealer to deal with this loss of acceleration issue. will get right on it as soon as possible.

I had my harness overheat, melted 7 or so wires and had to have wire surgery. The TSB was followed by my mechanic and saved me $2K for a wire harness. They added a thermal hydraulic line hose to protect the wiring from heat, and friction distress. I just wished I checked it sooner. I'll have to post my pictures once I get the credentials done with the modifications done to keep my NAFoSE (Normally Aspirated Focus SE) running

Anyone determine if this TSB also affects the demonic noise issuez; "chirping and popping noises"?
I feel like this is still a potential cause to my current radio issues.
I had my mechanic check my power in to the radio which is good but I'm wondering if there is something else to check.
Thoughts?

Nah separate issue.

Ok, I thought it was and figured someone had tied the issues together.

Hello guys, I have read the whole thread and have found similar pictures, but I just checked my focus today and took some pictures. I think I have the protective looms already, but there is a part on the bottom that I don't know if I should put more protection. The last image I marked the bottom part that I'm worried about. I appreciate your input! It seems that I can't upload links or images yet.

How is this crap not a recall already?

Had to go through this recently on my 2014, dealer wanted $360 or so to fix it, bitched at Ford and they covered all but $60 to repair it -- said screw it, figuring they'd replace the harness for the quoted price ($360) and when I got it back they had just simply repaired it and didn't even grind down or smooth the plastic on the intake that started the problem to begin with...what a crock of shit. Bitched more to Ford and eventually the dealer sent me a check for $60 -- happy it got sorted for free, but certainly not happy with the fix that I could have done in 30 minutes for $10.

Trouble Focusing Many Codes

Trouble Focusing Many Codes:
My new to me in the last 6 monthes 2013 (build date 10/12) Focus 2.0L SE flex/fuel just yesterday began being hard starting, running rough, keeps stalling, has little to no throttle response, experiencing low power when I drive taking a long time to achieve a diesent speed and has thrown several codes. In order on the scan tool the codes are P0192, P0340, P0344, P0365, P0369, and P06A7. I'm not sure if there is an order that I should attack these in? After doing lots of reading I wonder if TSB 15-0036 & code P06A7(sensor referance voltage 'b' circut range/performance) is the root of all these issues? I looked at the harness it has not been updated, and the back if it has chafing to the point i can barely see a wire or two. I added a temporary piece of insulation between the harness and manifold cleared the codes only to have them return in the same order. If this harness shorts will it cause the sensors to now all be bad needing replacement? Or should I be looking elsewhere? With all thses codes it's overwhelming where to begin.

Any insight is appreciated.

Call a dealer, tell them the main harness is chafing as found in the TSB. They will quote something like $300-350 to fix it. Tell them to pound sand and ask if they can get Ford to offer assistance. It will drop it to a $60 fix. Or follow the instructions in the TSB and fix it yourself. The techs just use cheap wire fixes (basically a heatshrink tube with solder you put the two wires up and then hit with a heat gun) and then wrap the harness back up...it's certainly only worth $60 the way they fix it.

Eventually that harness chafing will leave you dead on the side of the road.

This whole issue actually made it so I will never buy a Ford again -- their customer service was ******g abysmal when it came to that TSB and it effected all from 12-14. Fixed in 15.

thanks for your reply. The TSB fix should be easy, trying to figure if that is and will fix all the other codes or if the possible wiring issue has also trashed the sensors throwing codes?

It's the main wiring harness. That is the reason all the codes are there...trust me. There may be one or two after, but get that fixed and it'll most likely fix 80-90% of the codes. I had one left over after for an o2 sensor that had gone bad after the harness was fixed. A bad o2 sensor will not cause much of an issue at all.

Thanks again!

The codes and issues are what led me to this thread. My guess is because of the issues (hard starting, running rough, keeps stalling, has little to no throttle response, experiencing low power when I drive taking a long time to achieve a diesent speed.)chafing and codes (In order on the scan tool the codes are P0192, P0340, P0344, P0365, P0369, and P06A7.) that there is damage to the harness now. Has anyone done a harness wiring repair after having issues, the codes, and after finding the chafing on the main harness?
Any tips other than the TSB would be much appriciated?

I checked mine yesterday. The harness is so tight I could barely even get my finger behind it. It didn't feel worn through at all, but it did feel a little crimped back there.
My 2014 w/ 5 speed MT was built in 9/14 and doesn't have the protective loom......it's also very tight but didn't feel worn through. I put a piece of 1" loom approx. 5" long (purchased at HD) and used a zip tie rather than tape to secure it (because I didn't have tape and the zip tie was easier to get around the tight space). Thanks to the OP for this valuable info.....
