3.0 Journey

at some points the reading will be 70%, its like the system is trying to do a full burn, how ever it will not prompt one and then throws service exhaust system. I am not sure what the parameters are for the regen to start. when this happens I am in 8th gear and running about 1800-1900 rpm. All but one time this has been on the highway.

i'd suggest you dedicate one of the fields on that iDash to Voltage and start watching what's going on with the battery system.

when i see a 2022 with 30K miles, i'd suspect that the batts were likely original and likely need to be changed (or in the case of the Aux, better deleted).

aside from that, i''d follow the suggestions to do your own oil and fluid changes, to make sure they're current with the correct stuff.

any chance you have a Tazer? we've seen those throw some weird codes.

I thought the same thing, due to the amount of codes that its throwing, some are related and others are not. Especially with not codes point to the Exhaust or the dosing system. The dash has never displayed anything about needing to regen or the system being full. there is never communication about the Def system. how ever I have read the manual and noticed it should show messages.

You sir, have an electrical gremlin.

While I agree with a earlier poster that the type of oil used does effect how quickly the DPF fills up since it cannot burn off ash, that would generally take a lot more miles than 6 to go from 43% to 83%. Oil with certain additives do make you regen sooner and eventually require you to get it serviced/replaced quicker, but not that quick.

Prob the Can-C Star connector in the glovebox.
When I bought my 21, it would throw a code for the MAF and go into limp mode, then traction, ABS, etc After messing around with the bus, I found out the connector behind the glovebox was crap, causing the bus to randomly drop packets. When I wiggled the connector, everything lit up.
I replaced the connector and haven't had an issue that wasn't self caused since.

I love ChatGPT:


The Differential Pressure Sensor - Mopar (68302134AA) is an OEM sensor used primarily in Dodge, Jeep, Chrysler, and RAM vehicles with diesel engines. Its main function is to monitor the pressure difference across the Diesel Particulate Filter (DPF) in the exhaust system.

Function of the Differential Pressure Sensor (68302134AA):

1. Monitors DPF Condition:
   • Measures the pressure difference before and after the DPF.
   • As soot accumulates in the DPF, the pressure increases. The sensor detects this buildup.
2. Helps Trigger Regeneration:
   • When the sensor detects a high pressure differential (indicating soot buildup), the Engine Control Module (ECM) can trigger DPF regeneration—a process that burns off the soot.
3. Ensures Emission Compliance:
   • By accurately monitoring DPF health, the sensor helps maintain proper exhaust flow and ensures the vehicle meets emissions regulations.
4. Diagnostics:
   • If the sensor detects abnormal pressure readings, it can trigger check engine lights or DPF warnings, helping technicians diagnose exhaust or sensor issues.

Typical Symptoms of a Faulty Sensor:

• Poor fuel economy
• Loss of engine power
• Frequent DPF regeneration cycles
• Check engine light (CEL) or DPF warning
• Diagnostic trouble codes (DTCs) related to exhaust pressure

Location:

• Usually mounted on the firewall or engine bay, with tubes connected to both the upstream and downstream sides of the DPF.

Update! Dealer is not able to find any thing wrong, all components check out just fine, battery in a good state, boots have zero holes in them, injector trim is correct. Support ticket was placed.

Drove home last night 45 min, soot levels stayed around 19-20. 80 mph, 8th gear, 1800 rpm. going to replace air filter, fuel filter, oil and filter.

Really thinking about going on a diet.
