Intermittent limp mode with injection warning light,' pending' p1431 obd.
Identified recent increase in fuel consumption after replacement of ruptured rubber pipe to/from air pressure sensor to dpf. Dpf reading 38%.

Code reading identified as; broken oxygen sensor. Number digits read as; 1 = fuel air metering. 4 = fuel temp. sensor B circuit range/performance. 3 = cold start injector 1 malfunction. 1 = glow plug/heater circuit A malfunction.

No problem with vehicle performance otherwise.

Unable to identify location of fuel temperate sensor ( if it exists on this vehicle). Suspect fuel temp. sensor as would perhaps give cause of increased fuel consumption?

Any comments much appreciated.
Many thanks.

1431 is an DPF issue, this could be caused by your pressure pipe failure.
