Fault code P1429

Post by 310den »

(2004 307 SW 2.0 HDI 110)

I have the above fault, on PP2000 it shows as 'Permanent fault difference of exhaust pressure' so I took out the pressure sensor and there was a little water in it so dried it out but cannot clear fault so I will need a new one.
I looked at the readings and got this:

pef inlet/outlet pressure difference 118 mbars

engine speed 0 rpm

distance travelled since las regen 308km

output injected 38 mm3/stroke

air flow volume 0 m3/h

From what I have found on searching the 118 mbars is too high, what should the reading be?

Should be zero if the engine is not running. Might be a couple of mbar at idle, rising to about 50-60 at 3000 rpm. Suspect the sensor has had it. Surprised a 2.0 110 has a DPF but you learn something every day.... :)

Thanks. The car certainly does have the DPF... or rather it did! Done away with it today as going for the deletion of it so that will solve it.
