I just pulled the trailer to the lake, about 4.5hrs each way. It is the furthest I have pulled the trailer. I pulled two codes that I need your input on what they mean or their importance.

* P0236 Turbo Boost Sensor A Circuit Performance
* P0603 Internal Control Module KAM Error

Are these critical? The truck seemed to run fine. Trailer is about 7500lbs, the temp was about 90* outside. Got 10mpg.

 

I had the same codes along with 1211 a month ago or so when I pulled them after I pulled the trailer. I lugged it hard and threw the 1211, kinda knew that. The others, 0603 could just be from batteries unplugged, usually no biggy there. 0236 I read could be map sensor related, what color of map do you have? Like I said I threw the same codes and my truck is running fine so I'm not concerned at all now.

 

My MAP is grey. On the 0603, that is exactly what it was. I unhooked batteries to remove starter to fix dipstick. I am just going to clear them and check and see if I get them again. Truck runs fine otherwise. No more oil drip off the dipstick flang is really, really nice by the way!

 

What technic did you use to fix de dipstick flang?

Worked really well, so far.

 

Ah, OK, thanks, good to know it worked well.

 

I get the 1211 all the time when pulling real hard and the rpm's drop off really fast when topping a hill with the cruise on. Darin, you say you get it by lugging it? strange!

 

Actually it happened just like yours did glenn. As soon as I crested a hill I was just lugging it in od, no cruise, just pissing around really, and set it.
