i just replaced the o2 sensors upstream or before the cat. and added new wires due to poor maintenance bye the last owner.

 

Enter the code in the upper right corner.

Land-Rover B3457 OBD/DLC Error Code -

 

By those codes, your 3 amigos are on, 1590 and the other codes indicate you need to replace your MAF. When replacing it buy only a replacement MAF with matching part numbers, British Parts of Utah has a pretty good price.

 

alright i replaced the 2 o2 sensors before the cat ureka the truck runs better now. i went ahead and cleaned the maf and seemed to work better but now. but the truck is sluggish and has barely any power and a new code came up about the maf sensor/ so ive looked around and found just the insert for about 60 bucks. its exact bosch numbers 0 280 218 010 found on my maf. i just want some advice on replacing cleaning again or maybe used? thanks guys
