G'Day Fellas,

Posted this on the US site. Anybody know anything from this end?

G'day Fellas,

The truck had a sudden case of indigestion and had a pretty solid burp (HICUP!!), followed by a few soft burps.
Got home threw the AE on and got the P0344 code.
Luckily I always carry a couple spare CP Sensors. I've got a few F-Truck 7.3 owners on the road over the years buy having those spares with me. It's the first time it has happened to my truck.
I done a mates truck a brace of months ago and just asked him to order a couple of CP sensors from Clay (I have been using Clay's excellent service for years (my go to supplier)).
Anyway what I'm getting to is CPS Part Numbers:
The Sensors I'd been carrying were the 'Grey' CPS Part # F7TZ-12K073-B.
When the mate received the replacement CPS from RR it was Part # F4TZ-12K073-C and is a very dark grey colour and noted as 94-03 7.3.
Now the original CPS I pulled from my truck was "BLACK" with these numbers etched on it: 1825899 also 0812 and KC93.
I believe that Black was the original colour and that the upgraded was a Grey.
After fitting the Grey CPS Part # F7TZ-12K073-B the truck runs excellently and feels smoother at idle and lost the # 8 injector cackle .
So, the only CPS available from RR is the F4TZ-12K073-C.
What's the go with the Part# change? Is yet another upgrade or is Ford using another maker/supplier. The number etched on this CPS is 5F27.

Cheers Reg
