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?
