Coming from a Mondeo MK5, I half expected the S-Max to give me some useful info on DPF_Load & DPF_Soot, however it can only give me the weight of soot. I have no idea what is good, bad or indifferent. At least it could give me the Differential Pressure, but again, not sure if the figure is telling me the DP sensor is blocked.
The PCM registers the P2459 code when it detects that the exhaust pressure didn’t hit the right level or if the passive regeneration process didn’t follow the programmed frequency. The P2459 code can be caused by a bad DPF pressure sensor, a restricted DPF or exhaust system, accumulated soot, circuit problems, or an issue with the PCM.
google search "6.7 Coffee Table Book". page 79 shows where they are along the frame/DPF. If i remember correctly Bank 1, Sensor 2 is between the DOC and SCR. it would be the second sensor from the front (front being where the down pipe flange is). 2012 F250 Lariat CCSB SRW: H&S XRT w/ Gearheads tunes, Edge CTS, 5" FLO PRO DP Back w/ Muffler. DashCommand and Torque both read boost pressure as roughly -6psi with the engine off and at idle.. it only gets to 0 and positive pressures when the MAP reading equals and goes higher than the Baro, 144kpa. -6psi does actually make sense given the readings. 144kpa = 20.88psi. Mass air flow and intake air temperature sensors are located on the intake manifold of the Cummins 6.7L engine. NOx, O2, and differential pressure sensors are present on the exhaust manifold. You can find the crankshaft and camshaft position sensors on the left-hand side of the crank pulley beside each other. Furthermore, the EGR temperature sensor has a location on the crossover tube. diagnosing a diesel particulate filter differential pressure sensor 1: check voltage supply at plug. 2: check hoses to DPF from the sensor for leaks. 3: with the sensor connected, apply 1.

Hi there am just after some advice the local garage replaced my dpf pressure sensor and 2 pipes off it is it rite that read that they need programming as when he put it on he said it had a electrical problem soDBER.
