Hello. If there are only a few wires that are damaged, is he not able to just replace the damaged wires? If they are damaged all the way to the connector, he could either solder the new wires right up at the connector, or buy new connector terminals and crimp the new wires to the terminals and replace the connector terminals. It's rare that you would have to replace an entire wiring harness due to some damaged wires or connectors. Is that what you were wondering?
There's not really a tech sheet explaining how to replace the damaged wires, but basically when he locates a damaged wire, he should cut the damaged portion out, and solder in a new section and shrink tube those solder joints to keep them protected. If he needs, I can provide him with the wiring schematics for the car if he happens to need those. but it doesn't sound as if that's what he needs. If he does end up needing to replace connector terminals, he could remove one of the terminals and bring that terminal to Napa and match them up. They have a large assortment of terminals. He would need special crimpers though to install those terminals, so if he doesn't absolutely have to replace the connector terminals, I would suggest just cutting the wire a half inch from the connector and soldering the new wire to that. If the connector is damaged, then the dealer can get you new connectors with short wire leads attached that can easily be soldered to your existing wires. I wish I had some literature for you that would illustrate this, but it's pretty simple. I'm sure he'll know what I mean.
Let me take a look for a connector diagram. If you have a shorted wire or wires, then that should be addressed first. I will look into technical service bulletins as well though. One moment.
Here is a picture of the map sensor. orange circle around it. If possible, have him check for trouble codes and let me know if there are any. I can check into it further, but here is a TSB that may help him determine the cause if the MAP sensor wire damage isn't the issue. The trouble codes though will help me make sure to get you the correct information in the event that this one doesn't pertain to your situation.

Did this help at all? I just want to make sure that you have gotten the answer you came here for. Thank you.
let me check. one minute please
they are working on my computer. I have never had that complaint before either. Try using a different browser maybe
If you'd like, I can email them to you instead
You are correct.
The P0113 points to the air intake temperature sensor. TMAP
The P0118 Points to the MAP sensor.
Earlier you mentioned damaged wiring. Has all that been repaired?
Here is some information on the MAP and TMAP TESTING
Ok. you need the procedure to replace the sensors?
That may help me to better understand what you need help with.
I'm not sure what the maximum size is on here. I have not had anyone mention that they had to reduce the size in the past though.
if your phone takes larger than normal pictures, you may have to resize them. Only one way to find out.
oh, in that case, it may very possibly be too large. I dont know much about cameras or any of that, but once you get the pictures posted, I'll respond as soon as I can and let you know what I think about getting the wiring damage repaired.
Ok. I don't see any damaged wiring, however, the last picture you provided, the one with FAE 15066 printed on it is the MAP. It looks like someone had attempted to replace this since the bolt is broken. The end of the broken bolt is rusty, so this was probably attempted a while ago and I assume that they decided not to replace the sensor since they had broken a bolt and were probably afraid of breaking the other bolt. That's the impression I get from the picture
I am going to have to open this for the other experts. For the time being, I have access only to my phone which is very difficult to work on and no access to diagrams or anything else. Sit tight and someone will likely be by shortly to further assist you. Sorry about that.
I had a medical emergency, sorry about that. I'm also sorry nobody tried to assist you when I had opened it back up. I was hoping someone would have been able to help you get this resolved. Since nobody was able, I will do my very best. I believe the picture you provided here is the MAP sensor. I will give you all the information I have on the MAP sensor. Hopefully it will help you. If you would like, I can get you everything related to the TMAP as well.
Here is what I have for the air filter housing.

How did it go?
