ANNOUNCEMENT: EGT 13!

EGT 13, when it's open circuit, the sensor is bad, unplugged, not installed in your delete kit, what have you causes the truck to enter the following strategy:

  • PCM Power output limited.
  • A "Pull Over Safely and Shut Vehicle Off" message may display in your instrument cluster.
  • A 1-hour no-crank condition.
If you suspect this is your issue, and you're stranded, try the following.

  1. Vehicle in PARK
  2. Parking brake SET
  3. Key in the ON position
  4. Open hood
  5. Near the RH battery, there is a single wire disconnect. It is attached to the battery box. Remove it from the battery box and disconnect it.
  6. Touch the end headed towards the starter to the POSITIVE terminal of the battery.
The truck should start. Reconnect the wire, close the hood, and check for codes. You will likely have a code for EGT-13 open circuit, over temp, out of range.

THE AUTHOR OF THIS POST ASSUMES NO RESPONSIBILITY FOR THE INFORMATION PROVIDED WITHIN. USE THE AFOREMENTIONED INFORMATION PROVIDED AT YOUR OWN RISK TO SELF, VEHICLE, AND PROPERTY.

Hope this is of some help to folks on here. I have seen two or three posts in the last 3 or 4 days regarding this, and helped a stranded member out over the phone with this same problem.

Hope this post is useful to some, if not, most.

The last EGT sensor in the exhaust, right behind where the DPF should be.

Is it the brown wire with the green tracer and some kind of a plastic connector?

This saved me a helluva lotta trouble, tonight..

I got distracted while changing tunes, and installed the dpf on tune w/o the dpf.. whoops.. it was idling, and I could hear the egt cycling.. I got no codes, and no problems while it was idling, but confirmed via the mini maxx I had tuned as if a dpf was present..

After re tuning, it would not crank.. I checked relays and fuses, and re programmed no less than six times.. then I got to thinking about what I had did, and recalled this thread from when I was scouting this joint..

Thank you thank you thank you.. at one point, I was thinking I fried my pcm.. that didn't last long, though, because I realized it was communicating thoroughly during programming.. this little trick saved me a helluva stressful situation..

does this happen everytime you put a delete kit on or a stright pipe and unplug all the sensor in the pipe? is their a way to avoid it? after you do the delete etc can you wait an hour and it i will start after that? cant you just do the delete and load tunes on all at once then it wont care or does it take an hour after you try to start it

make sure and tune it first- then do the physical deletes..

if the egr and the sensors in the DPF don't register on the OE tune, or the tune you've loaded, you'll get the lock out- and if you run it deleted with tunes looking for those sensors, it will pull one of those 'stop safely' messages on your info center, and kill the engine on it's own accord..

oh.. if you're using H&S, only the HD300 tunes will work with the EGR gone..

bingo...

if you're using a tuner that ignores them, you're good.. if you're using a tuner that requires them to be absent, you're good.. if you're mixing the two schools of though, you're not good..

H&S ignores the exhaust sensors.. it ignores the EGR while using the hd300 family.. I think it's SCT that requires the sensor to still be present (exhaust bungs in exhaust with a sensor present)..

I'm new to the 6.4 world (previously a 6.0 owner). I unplugged all the sensors and the truck fired up and ran just fine (had to move to a different shop in order to attempt straight pipe install). After moving, I went to start the truck and everything came on but no click/turn over/nothing. I bought an SCT and an exhaust without bungs (which is yet to be installed), from want I understand I have to have sensors plugged in for the engine to run. So my question is, why would the truck run fine and then all of a sudden not fire? FYI this thread saved my a** this evening, thanks a million for the info!
