Lambda Sensors

Does anyone know the recommended change intervals for the lambda sensor on the BA engine...??? According to the Bosch website they should be replaced at intervals depending on the type fitted (heated ones last a lot longer than unheated, for example). I don't know if Bosch make one for the BA or if we're limited to Mazda supplied parts...

Not sure, but how do you check to see if it needs replacing?

I dunno, unless Bosch or Mazda service manuals have info. Maybe you just replace it at the recommended time and that's that. A precautionary measure I guess, like we do with a lot of "lifed" aircraft parts.

Yeah - you're supposed to scrap it and buy a new one before the lambda sensors go ...

How much are these roughly and where from?

From your Mazda dealer (scary price) or local Bosch agent (scary-ish)???
I would phone around now but I think they all close lunchtime on Saturdays....

There about £40 squids for a Zetec Escort apparently, I was told they aren't car specific and a local motor factor might be able to sort one out. Someone also told me to change mine as it might help hot starting and general good running/economy . Never did it though so I can't verify any of this. :oops:
