Title: lambda sensor question
Post by: pitchy on 19 March 2010, 17:45

ive been offered some lambda sensors ( my front 1 is throwin up a light ) thing is theyre of a T reg and mines a 02 aum will they be ok ?
also my light is on , code reader says heater circuit bank 1 , my first 2 weeks of ownership i was getting 15mpg which i put down to lambda bein down , thing is ive been driving like my grandad for a week and ive been getting 35mpg, went down the m1 a few j's today and got 50mpg! , does this mean the lambda is not totaly knackered?
cheers

a T reg will only have one sensor. It should have a part number on it that you can match up to yours.

something dodgy going on there then. If it's your pre-cat (wideband) that needs replacing then nothing from an AGU will work as me5 only uses narrowband.
