Help anybody.
On my 2007 passat 2.0 FSI there is an open circuit in the high fuel pressure sensor driving me nuts, I changed the sensor and still getting an open circuit. As I do not have the electric schematic I can not trace it.

Did you get the recall done for the fuel pump...? First step would be to check if your car is covered under that...

what he is looking for is the ECU to the sensor "pin outs" ,I have been looking also in regards to this post, but unlike the B5's wiring schematics which are readily available, VW seems to regard (B6's) as a National Secret.

I may use them as a reference the B5 my friend.
Is this the first page of what you’re looking for..?


If so send me a message and I can help you out with the rest of the wiring diagrams. Sorry, better to be late than never!

I’m unable to find out about the high pressure pump recall, do you have any idea when it happen?
The high pump seems that it needs to be primed before allowing normal acceleration. I can not find how to correct the problem.

Thanks for the information.

I had the module on my Passat done by VW dealer, I had the impression that the high pressure pump was recalled also. The pump located on the engine is giving me p2494, Fuel Pressure Regulator 2 Control Circuit/Open, I had replaced one of the regulator on the pump already but still have the problem. Can be that the regulator on the top has the open circuit?

I bought a new Hitachi high pressure fuel pump, the info that I got from Hitachi is that a P2294 is caused by a faulty sensor on the one I pictured.

A 15 amps fuse missing was the culprit.

Does anyone know what fuse this may be. I am having the same issue. On my 2nd hpfp and multiple other parts. Replaced new flashed ecm. Getting 4.5 v on the purple wire but nothing from red.
