Call Mike on 0161 873 8300 and tell him what model.
I have just bought a new Transit alternator from him at a very good price.
PS I have no connection with them other than as a customer .

Albatross, if you want to borrow an ELM cable to double check the live data before you jump, I might be able to help.

Might be worth posting the Bosch part number from the side of the MAF. The 2.6 / 3.2 don't have a separate intake air temperature sensor. Not sure if that makes the MAF sensor different to the 2.5/3.0. :-/

Kevin

Its an interesting one as the 2.5/3.0 makes little or no use of the air temp in the correction anyway. Which is not surprising when you consider that air mass has already taken air temp into consideration anyway effectively!
would the maf know the air temp? surely it can only know the amount of air, not its temp/ Obviously this would vary with temp for a given load though...


It does not need to know the air temp in reality....just the mass of the air......and then it supplies a corresponding mass of fuel  :y
Yup, my understanding :y

So why do early ones have air temp sensor  :-/

Having just received a very welcome PM from Kieran, I have just ordered a MAF sensor for £33.50 which will be here this week.

That's £100 off what I thought was a good deal and £150 less than the retail price from Vx.

No bl00dy wonder they're called "stealers".

Thanks Kieran and Olympia what a STAR! :y

I was just wondering if the MAF had a built in air temp sensor which wasn't present on earlier cars, thus rendering an early MAF sensor incompatible. It has 2 additional pins above and beyond the power supply and sensor output, suggesting another sensor.

live data shows an IAT reading so it's measuring it somewhere. I agree it won't add a huge correction.  I guess there are times when the engine is not using MAF as the primary load input, even if only in limp-home, and knowing IAT is useful then. It's also going to be a big factor in cranking and startup where heat soak might have got to the induction system, although coolant temperature would give it a big clue there too.

If it's the one pictured on Ebay, I'm not 100% sure it's the right one.  :-/ Might be best to double check the Bosch part number.
