HELP - CEL P24C9 & P24B5 CODES:

[DieselScott]

Hey man, have you heard or ran into problems replacing the sensor.? I have pb blaster on it now and next step is heating it up w butane torch but I couldn’t break it loose w opened end wrench ordered the sensor socke. Also did you have to drop the exhaust to get the module loose?

How’d the sensor replacement go? My truck threw the same codes again but I’m out of warranty. I see the part is available online so I’m gonna attempt the replacement. Did you need to drop the exhaust?

Waking a dead thread, my 23 Ram 2500 just threw these codes. Not part of the TSB according to the website and NHTSA lookup. Did anyone have luck with just the new sensor install?

Lol not a dead thread now, I'm at 141,000 km and just had a great timed regen that really cleared out the DPF (5% at start now, haven't seen that in years). Then today poof threw two codes when reversing in my driveway, the same old P24B5 and P24C9.

I've cleared them for now and will monitor. May look at removing and cleaning the sensor but this seems to always happen in the winder (yuck).
