After my stage 2 delete, one of the codes I get is 244A, DPF pressure and on the overhead service required, see dealer. My truck thinks the DPF is full. The pressure tubes are hanging loose and the electrical connector is plugged in. Also, I have the EGR tube blocked, no plates yet, and plugged in with the valve disk in the air inlet removed. Is there any way to shut off this code without a tuner? I read that a 110 and 390 ohm 1/2 watt resistor would work. Anyone else heard of this? A 1/2 watt resistor is pretty big and hard to find in those exact ohm values. The reason I ask is that my e brake is working only intermittently when turned on.

 

That's what we do in the shop for DPF deletes, if the customer doesn't have aftermarket software like Smarty in the ECM.

 

I finally found the resistors locally and installed them. Actually another member had recommended this fix to me in one of my previous posts. I just couldn't find the 110 and our electrician told me that a 1/2 watt resistor was as big as a little boys ..., finger. He was wrong. All I was trying to do was get rid of the 244A code. Also the service required was for the 30,000 mile clean emissions stuff, not for a clogged DPF. Should I bring the box of parts to the dealer for cleaning? After putting the resistors in and driving for awhile, I checked codes using the 3 key jig. I almost ran out of paper there were so many. This is also due to removing the ETC valve. I got the lightning bolt and the check engine light is still on. I'm going to remove the resistors from the pressure sensor since they didn't get rid of the 244A code and work my way back to maybe re-installing the butterfly and unplugging the EGR. I only got 3 codes that way. The truck runs fine despite all the codes. Again, DPF and CAT removed, simms in the temp sensors, and pressure plug, EGR plugged in / crossover tube blocked, intake butterfly removed.
