P2B95

[At Risk Ute]

Threw it this morning (don‘t be jelly of my summer weather), read it on the tazer, and the code went away on its own next time I started her up.

Anyone else throw this code?

Found this on the internet....

During diagnosis a technician may find DTC P2B95 (Injection Pulse Performance During Cold Start) set in the Engine Control Module (ECM). Cause This may be caused by a calibration concern setting a false DTC. Correction Reprogram the Engine Control Module (ECM).

Just got one of these and was unable to clear it with JSCAN. Did your CEL ever come back?
5500 mile 2023 JLUR 2.0T.

I spoke with one of the Tech at the dealer. This is a known issue with vehicles at altitude and Jeep will probably have software or a patch released to fix this issue. They told me they could clear it but because my daily drives are between 6500 & 1200 feet it will return.

I had this code on my 2023 last week. Dealer hadn’t seen it before and wanted to test resistance in 25 different harnesses, but it went away after a few drives. I live at 6000 ft. Thanks for the update!

Close! 7500 feet.

Agree it’s an elevation thing but only happens with my ‘22 (not the ‘21). Haven‘t thrown a code since that pic but still occasionally get the “Performance Limited“ warning at WOT in the mountains.

’21 motor is Italian while ‘22 is American. Dunno if that’s a possible culprit.

By heaven, I was referring to the angelic beams of light coming through in your picture.
But elevation, yes.
