Customer Question

I have a 2007 Ram diesel 6.7L. it has a code P242F for the DPF filter, I took it to a place to get the DPF cleaned and 2 sensors replaced. The code still comes on and my scanner and my mechanics scanner can not clear the code.

Hi there.

Potential causes for this condition are excessive ash in the system from the engine not getting a high-enough temperature to effectuate self-cleaning; a stuck-open EGR valve; faulty exhaust temperature sensors.

To repair this issue, first inspect the system for accumulated ash or debris - make sure EGR is not suck open. Clean and service as required. Next, connect a capable scan tool and monitor exhaust temperature sensors; temps should be within 6 degrees Celsius of one another. If not, replace the sensor that's out of context.
