Pressure differential sensor location

[gumby6371]

Just ran planet on the 307 as it's down on power but no EML or fault messages coming up, it picked up turbo pressure low and FAP not present. When I went into more detail I got pressure differential at zero. I presume the FAP is pretty well blocked causing low pressure to the turbo and the pressure sensor is fubar'd giving the not present message.
It occurred to me that the sensor may be the same as the redundant one in my 406 but as I didn't do the gutting myself I have no idea where it is, any ideas where it is on a 2.2 and what the part number is?
The 307 part is 1619 Z9, which Google tells me is an uprated version of 1618 09 which seems to be shared across the 307 HDI engine flavours so fingers crossed the 406 as well.

The good lady is still nervous about the de-fap so I'll see if the sensor is at fault first.

Cheers

Not sure exactly where it is, but it's somewhere below the brake servo. From underneath, you should be able to follow the two pressure sensing pipes from the cat/fap assembly back up to it.

A zero reading may just indicate one or both pipes detached......

As you look at the engine it's on the left just behind the driver's side headlight right at the top I can take a picture for you if that will help

On a 2.2HDi Coupe, it's exactly where Doggy says.
So assuming the saloon is the same, it's on the engine side of the bulkhead, more or less opposite where your passenger's feet would be. Look for a brown 2 pin connector.

Ignore me thought you were asking about the 307

Look for a brown 2 pin connector.

By the by, a bit of excitement there as Sedre wouldn't start, just told me it needed reinstalling. Where's my back up? Anywhere? This back up disk? That back up disk? Lap top? Nowhere, seems I've kind of, er, deleted my back up. Oh crap, that took ages to download one tiny piece at a time. On the plus side, I managed to download the keygen no problemo, generated a new one and now I have Sedre back, but... Anyone know where I can download it?

If it's only 2 pin then it won't work as the 307 is 3 pin

Sedre says 3 way, black

Thanks gents, I'll investigate when I get chance
