Wanted to know other peoples opinion and see if I have missed anything Dropped oil and new filter in as well Mil light is on as well as a solid dpf followed by flashing dpf Thanks |
Did you carry out the "Oil data" reset after changing the oil?
|
Yes I tried all the combinations of the manual wire to ground reset including 10 presses. 5 presses and finally the 2 press force regen. I'm not a novice been on the spanners for 20yrs jaguar for and vw trained Just the codes keep pointing back at exhaust pressure sensor. No amount of cleating the codes either via obd or earth cable seem to work
|
So you clear the codes, and the come straight back?
Do you have the option on your scan tool to reset the DPF values? Can you Perform injection amount correction procedure, then perform manual diesel particulate filter regeneration procedure? Can you monitor live data/Pids? |
All codes reset. All environmental data reset. Trued both manual 2 pumps force regen and also obd force regen still no joy. Cleaned egr out. Cleaned maf sensor and another one I found on the manifold. Replaced the ambient air sensor and exhaust pressure sensor with £280 supplied Mazda part. Apart from throwing it all in the bin what else can I try?
|
Did you fit a genuine or aftermarket DPF?
Workshop manual does talk of possible ECU faults. Is it a BK or BL MAzda 3? & what year? |
DTC P242F
Diesel particulate filter restriction-soot accumulation POSSIBLE CAUSE • Exhaust gas pressure sensor piping restriction and/or damaged • Diesel particulate filter restriction and/or damaged • PCM malfunction DTC P2463:00 Diesel particulate filter restriction-soot accumulation POSSIBLE CAUSE • Exhaust gas pressure sensor piping restriction and/or damaged • Diesel particulate filter restriction and/or damaged • PCM malfunction |
Changed The rubber pipes from dpf pickups. And the additional pipes to sensor also flushed the metal section on the engine block so defo not that there all clean
|
Did you find a fix?
