compared to Ford Ea-El Map Sensor E7DF-9F479-A2A

1. Differance?
2. Is it just product code?
3. Interchange?

thanks for your time guys. :)

I think that number is the OEM's part number.

+1, >PBT-GF30< is the manufacturers part number, others are Fords codes.

Couldn't be more wrong if you tried LOL!

Try googling PBT-GF30 and you will find ppl telling you that it's a noise suppression capacitor for the radio... or a MAF...


...when in fact PBT-GF30 is an abbreviation for "Polybutylene terephthalate and 30% glass fibre".

That MAP is a unique-to-Ford part that AFAIK you won't find on any vehicles other than Fords, everyone else being out of step and using analogue (0-5V) MAP or TMAP sensors rather than digital (frequency-based) as this is. Even Ford Aust relented and moved to an analogue, manifold-mounted TMAP on the AU and later engines.

I once found an output curve for the Ford digital MAP on a US website and can confirm that the EF MAP transfer table is consistent with the US spec.

So they should be interchangeable.

In my opinion (and it's only my opinion), they are the SAME unit.
