CEL P0420 fault code.
Hi, had the cel come on my car at the wkend got myself a fault reader and it's has a P0420 code. Does anybody know what it is, possible severity or can I just erase it?
The car's a 2005 wrx which was standard up till the autumn, where I had Alan Jeffery fit a de-cat up pipe, Prodrive sportscat dp, de-cat centre, ic pipe, Prodrive boost solenoid and supporting mods to get to 278 bhp. It was then re-mapped by them.
Any help greatly appreciated Lee

P0420 is Catalyst System Efficiency Below Threshold (Bank 1)
If is this code,i think your front Lambda sensor is gone,cost around from £88-£120 from eBay for Denso genuine one or from dealer around £286.
