Hempstead Posted February 22, 2008 Share Posted February 22, 2008 I have a 08 6.4l that was towed in that died while driving on interstate. checked codes-po297(overspeed-95.09 mph) and p200e (cat overtemp bank one). I cleared the codes and retested-pass checked oil-ok,checked dpf sensor for blockage-ok, checked egt sensors-all ok. Truck only has 650 miles. I say that it is just a concidence that they were on a on-ramp merging and the truck was going thru a regen. Anyone else seen this code?

Keith Browning Posted February 22, 2008 Share Posted February 22, 2008 I haven't seen any over temperature codes or failures but I have had several EGT sensors go bad. All of them had circuit codes and I was able to verify the faults. I read the code description and it does say that this could be caused by operating conditions which is strange to me, strange that the ECM is not programmed to recognize the temperature rise and stop regeneration if it is occurring long before the 1526 and 1742 degree F marks. Did you call the HotLine and see what they may have seen and what they have to say? Quote Link to comment Share on other sites More sharing options...
Hempstead Posted February 22, 2008 Author Share Posted February 22, 2008 Hotline told me to check and see if there was fuel in the oil-which there was not. check the dpf sensor for any blockage-was clear, andto check egt sesnors for proper operation-which all were ok. I checked to see if there was a later calibration for the pcm but it had the latest. I just think that it was a strange series of events.

Your customer was on a on ramp merging and got his truck up over 95 mph /forums/images/%%GRAEMLIN_URL%%/scratchhead.gifWhat's wrong with this picture? I could understand the temp issue if it was in a regen at full throttle but the speed at the same time???I want to see a video of a 08 F-series being able to get up to that speed that quick.I think somebody is not telling the truth here...

Keith Browning Posted February 23, 2008 Share Posted February 23, 2008 That might explain the high EGT's... he had his afterburners lit! /forums/images/%%GRAEMLIN_URL%%/eeeesh.gif Quote Link to comment Share on other sites More sharing options...
Jim Warman Posted February 23, 2008 Share Posted February 23, 2008 Two or three weeks ago, we were hovering around -40 ~ -30C... Now we are in the 0C area (32F for the challenged). I had several units with EGT out of range codes... no time for anything more than a code scan and a sensor coherency test.. and come up with nothing amiss. While we have yet to see any serious 6.4 concerns, it is beginning to look like these sensors can't understand northern Alberta winters.

The overspeed could have occured and stored a code quite some time before this event.... Quote Link to comment Share on other sites More sharing options...
Hempstead Posted February 24, 2008 Author Share Posted February 24, 2008 No he wasn't going 95 mph when merging, he was going 77 mph when merging, that is what was in freeze frame just before the truck shut down. THe overspeed code was set shortly before the overtemp code going by the freeze frame there was a 25 mile difference. Quote Link to comment Share on other sites More sharing options...
Hempstead Posted February 26, 2008 Author Share Posted February 26, 2008 I finally got it to shut down on me. I got it back to the shop and checked codes and had p200e agian and p242e this time. The p242e is for egt 13. followed the pinpoint tests and replaced egt 13. test drove-so far so good. Quote Link to comment Share on other sites More sharing options...
