I replaced the EGR valve now I’ve got a PO406

Post by Rorkie » Mon May 10, 2021 9:21 pm

I replaced the ‘A’ bank (Offside/right) EGR valve on my 2009 Disco 3, all codes cleared happy days.

Now about 3 weeks later I’ve got the EML back on and a PO406 Exhaust Gas Recirculating Sensor ‘A’ Circuit high code.

Does anyone have a wiring diagram for the egr circuit or can tell me which of the five pins the 5v reference wire comes in on?

Thanks guys

2009 is the later model and the EGR's also need a firmware patch to delete from there too - Don't know where you are off hand, but Bodsy can sort it for you if you can't do it your self.
