Eddie84 Posted March 11, 2022 Share Posted March 11, 2022 Hi, I had off car DPF cleaning done. The company provided me with the following before and after results. All was good for 10 min before the dash light came back on with the p244B error. Is the flow rate after the cleaning ok? Is the issue somewhere else? Please help. Kind regards, Eddie Quote Link to comment Share on other sites More sharing options...
Frembrit Posted March 11, 2022 Share Posted March 11, 2022 Fuel vaporiser most likely blocked so it can't get hot enough to do a regen. No idea on those figures, but to me it looks like the flow is worse after the clean. Do you have a Transit or Transit Custom and which engine do you have? 2.2?

Eddie84 Posted March 11, 2022 Author Share Posted March 11, 2022 vaporiser was cleaned too. After reinstalling the dpf all was good for 10 min. The engine didn't even got up to temperature. Quote Link to comment Share on other sites More sharing options...
Eddie84 Posted March 12, 2022 Author Share Posted March 12, 2022 I have checked the voltage on DPF pressure sensor. Reference wire shows 5 volts and signal wire 4.75 volt with ignition in accessory mode. When sensor is disconnected both wires show 5 volts. Does that mean the pressure sensor is dead?
