SOURCE: My Grand caravan displays fault codes P0401 & P0406

Off the top of my head I beleieve these are EGR codes, the EGR valve is located on the top front left side of the engine, you may need a valve and solenoid.

Saturn Astra P0420 Problem


Hi , A PO420 code on all cars and trucks is a bank 1 cat failure and this code is determined by the ECM (Engine Control Module) by 2 sensors the Up stream O/2 sensor (otherwise known by some car manufactures as a Air/fuel sensor) and the down stream O/2 sensor. If you remove the Cat you will still receive a code due to the down stream O/2 is looking for certain gases which is produce only by the Cat as exhaust gases is passing through it. So yes there is no way around it if your getting a PO420 it is best to first take your car into a reputable shop to find out what is causing the cat to fail in the first place ( most likely due to O/2 sensor failure ) and possibly other things that could of failed leading to O/2 sensor failures along with the Cat.

Hope this answers your question.

2007 Dodge Grand Caravan Engine Light Code P 0405 ?


P0405 is an Exhaust Gas Recirculation fault. This could be a faulty valve. You could try cleaning the valve first, chances are it will need to be replaced in the long run. Hope this helps...
