Hi danny,

 

There is a wealth of info on this forum from past members who are no longer around.

I recommend you search limp mode in the top right corner.. I just did - and found lots of great threads.

 

Good Luck

MAP sensor and manifold pressure sensor are the same item.

I have the same issue, a garage told me it COULD be an air leak from a pipe. Now I'm only going by what they said, which was, check all the pipes :/

Hmmm ok there's loads.

 

I've ordered a MAF sensor and hoping it works

[Argrdnr]

Fault codes from the reader says its the MAF and EGR, well Diff pres feedback sens upstream hose off/plugged. Can I get cleaner for this?

[Argrdnr]

is this the EGR valve???

please help

hello

       you do not say what year type etc, I have had this on a 1995 diesel and it was the vacuum pipes feeding the manifold pressure sensor that is located behind the instruments it was blocked with oil and the pressure was finding it hard to get to the sensor,

there can be other reasons for this fault, with the early models when it went in to limp mode it is possible to reset it by backing off the throttle, on the later ones the ignition has to be switched off

Your picture is of the secondary air injection system as far as i can tell. If its a split pipe i'd start by looking at the one on the brake servo firstly as I've found mine had split. I also had the two pipes from the sai system that go up to the module near the battery fall apart although you would probabbly notice if they had gone as mine sounded like there was a large hole in the exhaust when those pipes split.

Thanks Brian, every picture I've found tells me that the pic I uploaded looks alot like the EGR, I'm confused lol

[BrianH]

Have a look at this thread - this looks to be the diesel engine but at least should give a clue of where your looking to start with. Theres too much snow here to look on mine unfortunately. I'm not even sure without looking if mine even has one either. Your going to get people confused by posting your problem in other peoples threads - either continue your own or create a new one where necessary

I can't find any posts on here mentioning egr and petrol that seem to be relevant but that could be down to the way i'm searching.

Here's a diagram showing location of various bits and bobs on 2.0/2.3L petrol engines
