Stuck in regen low #5 EGT

[77cruiser]

Started a regen towing today it took 15 miles to get up to 900 deg. & only got up to 940.
Needless to say regen never finished in 45 miles.
2 codes from my Idash PO422 & P24A0

Failed EGT sensor, bad thermostats and/or bad 9th injector

FWIW I had a bad EGT Sensor on my LML off the DOC. Regen would start and would get to somewhere in the ballpark of 900-1000 degrees. Then it would shoot up to 1600 degrees and Regen would stop. Temps would start to cool off and the sensor would read normal again. Regen would start again and the temps would shoot up again. Regen time progressively got longer and longer until it finally set a code. During normal driving the sensor was accurate.

Thanks, it's a good possibility it will be going for weight loss.
