[QUOTE="me2, post: 654173, member: 3825"] My 6.4 almost stranded me. About 200 miles from home on my last trip, the check engine light came on when the truck was idling. I checked the fluids and everything was fine, so I continued on my way, taking things easy at 60 MPH. About 50 miles later the information display bell starts dinging and I get the "Stop Safely Soon" message. That and the truck was continually regenning and it was smoking heavily (blue and white) when it was regenning. Of course I am in the middle of no man's land when this happens. At least it was daytime and the weather was nice and not 2AM in a storm, which it could have easily been. I pulled over and checked the fluids, especially the coolant. All the levels were fine. I let it cool down. I started it up. The CEL was on, but the SSS message was gone. I drove the rest of the way home at 50 MPH, regenning on and off all the way. When I got home I connected Auto Enginuity and pulled codes. P2033/ P2084. Middle EGT sensor not working correctly. I picked one up at the dealership for $70. The problem was getting the old EGT sensor out of the PDF. It was seized in really well. I applied penetrant to it morning and night for 4 days and drove it during that time until it would come out. Here are some hints if you ever need to remove yours. 1) Apply penetrant, liberally and often. 2) I drove my truck daily. I think the hot/cold cycling helped the penetrant do its thing. 3) Cut the sensor wire and use a good quality, tight 6 point 13mm socket instead of a flare nut wrench. BTW, its not easy to find a good quality 13mm flare nut wrench in stock ! The sensor was tight, tight, tight every time I tried to remove it until the time it came loose. Then it was like it was just installed yesterday, it came out easily. I was shocked. I guess it took that long for the penetrant to do its thing. The truck was a total pig with the EGT sensor not working. It burnt a ton of fuel. Like twice as much as it usually did. And it was smoking really bad sometimes. People would pass me shaking their fists. We are at the end of renovating our house and I needed my truck and had no choice but to use it for hauling furniture and materials. I'm totally pi$$ed that a single sensor can bring the entire truck to its knees. I found out that I'm lucky. When this happens to most people the PDF plugs and they continually get the "Stop Safely Soon" message, meaning they can't drive it at all. Its just like the CPS on the 7.3s. Didn't Ford/International learn anything from that experience ? I know, I know... I should have done a delete. I'm going to do a delete all right... the entire 6.4 engine ! LOL. The other lesson from this experience is that Auto Enginuity probably paid for itself with this issue alone. I doubt the dealership would have got that sensor out any easier than I did and the bill would have been $$$$. With AE I know what the problem was 5 minutes after I hooked it up. I am going to keep it in the truck at all times now. BTW, there are three identical EGT sensors on the PDF. One should probably carry a spare sensor and some penetrant and a high quality 13mm flare nut wrench and a good 13mm 6 point socket and drive setup, because if any one of those sensors fails, the truck is essentially in limp mode or worse.
