Thanks for asking your question. I will try and help you out.
Code 3242-2 is defined as DPF intake has temperature erratic.
Code 3251-2 is defined as DPF differential pressure erratic.
These sensors are located in the sensor box on the dpf. You most likely have a faulty sensor box.
I would inspect and clean the connections for these sensors in the dpf. If the problem continues. Next I would make sure the harness that connects them is ok. If it is. I would replace the sensor box.Please reply back if you need more help or have more questions. I am happy to assist.
