Coming home from the gym a little while, got on the gas a little (75%ish)and got these codes along with half engine light:
3100
2ABC
29F3
2F08

I have JB4, catless exhaust, and DCI for mods

Any advice as to what this means?

[grzes]

2ABC - Turbocharger Boost Sensor 'a' circuit low
29F3 - Low Pressure Fuel System Sensor Circuit High
2F08 - Intake Air Temperature Sensor 1 Circuit Low

but I can't find anything for 3100 unless you wrote the code wrong
Now what it means, well hopefully someone with some experience can tell

[PR3CI5N]

2ABC: charging pressure sensor, electrical
29F3: fuel pressure sensor, electrical
2F08: inlet air temperature sensor, signal
3100: not sure

[grzes]

3100 Boost-pressure control, deactivation
found this post where 3100 code was mentioned

Back from the gym?
Now you gone and done it.

Check your charge pipe, I had similar codes when my charge pipe broke. I didn't have the fuel pressure one, but I had the other ones I believe

[NReed904]

Thanks everyone for the replies. I'm going to check my lower charge pipe. I checked the upper and it was intact.

[NReed904]

Upper charge pipe was off, I didn't look closely enough at it on my initial inspection. Now that I've put it back on, I'm still getting the half engine light and a rough idle (no misfires). The idle seems to get a little worse when I access the JB4 menu. After putting the charge pipe back on (not broken, aftermarket and has a rubber coupling) I still had the half engine light so I disconnected the battery (about 5 secs, not long). Once putting it back on, the half engine light clears but then comes back after some idle. It may have been a coincidence but the half engine light came back on when I accessed JB4s menu.

What are the new codes. Clear all codes with jb4 and see what comes back if anything.

Also get proper charge pipe with c-clip mount.

I attempted to clear the codes last night after reinstalling my charge pipe but could not get the 3100 to clear until I disconnected the battery. After disconnecting, the 3100 came back. This morning I pulled the codes before work and only got the 3100 but I haven't drove the car since disconnecting the battery, only idled a little. There may be other codes that pop up with some driving, I will check when I get home.

3100 is not a real code. It pops up due to something else. It basically tells you there was / is a code / problem / event which cause the car to go into limp mode. Does not elude to what that event was.

Bringing this back as I have similar codes and limp mode. What was the cause and cost to fix?

[cochran]

i have these exact same codes. did you find out what the problem was?

[B335T E92]

What ended up fixing it for me was replacing all fuel sensors and doing a fuel adaptation reset though INPA. A simple adaptation reset through JB4 or MHD will not work. Trust me.

It is notorious on this platform for one code to trigger another. Its just the DME's elaborate way for shutting stuff down when something isnt right.

The problem is your TMAP sensor or TMAP sensor scaling and/or voltage
