Engine Codes, post repair at local shop
So I had my 02 Xterra in for a no start issue the other day. Prior to the replacement of the battery and starter I scanned the truck and found these codes:
P0328-Knock Sensor/Circuit B1
P0174-Fuel System Lean
They stated nothing about the codes I provided them and told me my battery needed to be changed and my starter replaced so I told them to go ahead and do the work. I go the truck back later that evening and it ran but rough started and my electrical seemed a bit wonky ie. the remote would not unlock the tailgate but the inside switch would, that never happened before. I ran it for a day for about 25kms. It sat the next two days and again no start but with additional codes now:
P0420-Catalyst System Bank 1
P0600-A/T Communication Line
Any thoughts ??
