2006 Posted January 10, 2015 Share Posted January 10, 2015 I had a 6.7 F350 with 10,000 miles with an exhaust sensor code, P200C and P200E. The freeze frame showed EGT13 reading over 2000F, all the others were about 150F. I followed the TSB and replaced EGT13. Under the TSB, there is was no diagnosing, I just replaced the sensor, cleared the codes and I was done with it. 300 miles later, the same codes came back for the same sensor. I remember there was a recent TSB about replacing the body harness connector at the EGT sensors. I can't find that TSB and it didn't come up for that VIN. Maybe the TSB was deleted? I depinned the EGT harness connector to check the pin fit and crimp, it looked ok and reinstalled it. I did a very light wiggle test of the harness while watching the pids, no problems seen. Next step, I swapped the new suspect sensor with another sensor. Road test, monitored all temperature pids, all were reading normal, then EGT13 started jumping a bit, then within a few seconds it climbed to its maximum, then the engine quit. I did another wiggle test in the shop, EGT13 starting jumping. At the end of it all, found a spread pin at the PCM harness connector causing the problem. I don't know why it spread, the pin out of the PCM was ok. The connector looked original and didn't look like it was apart before. I replaced the harness pin. Anyway, the truck is fixed and I just thought I'd post this to help someone with a repeat code... 2 Quote Link to comment Share on other sites More sharing options...
