2121, 2123 and P0700

[DFrank]

Check engine light was on. the three above Codes are shown.



The P0700 has come up in the past. the others are new.



I bogged around in some deep snow today, if that might be relevant.



Where is a good place to go look up codes?

Go back one page and look at the top of the posts for Cummins diagnostic codes.

Thanks. Sorry, I haven't been on here in a while.

The codes are related to pedal position. Probably won't worry about it.

how can I clear them out to see if they return? Is that dealer only, or can I have someone do that at an auto parts store?

I loaded an APP called EOBD codes for my I phone last night that has the codes listed as well.

They can be cleared by anyone with a scan tool or just let it go and if they aren't recurring, the check eng light will extinguish after 9 or so starts.
