What does the sensor do exactly?

And would you be able to tell it's clogged from say using a IIDTool?

my was block solid and it did not trigger any faults with IIDTool. i will see if i can feel any difference while driving tomorrow.

It measures boost to inform the ECU. Here's a good explanation.

I think it would be quicker to pull out a torx screw driver and do a visual inspection, compared to setting up an IIDTOOL. The IID will give you detailed information. But without knowing the "normal" readings to compare against I don't know how the IID tool would tell you it needs a clean. ______________________________

it was , i went out and it took me 5 min to pul MAP out,clean it and put it back in.so I will be doing this on a regular basis from now on. maybe every other oil change ( i do oil and filter every 5K km)

Nino,
How easy/difficult job is it to remove the inlet manifold to clean it?Any things to watch out for?Time it took? 2012 TDV8 Vogue SE 4.4

this two connectors are fiddly to unplug/remove

When I was doing my oil cooler fix, I had the map sensor out and let the tip of it soak in some brake cleaner.

Like Nino says, for all the effort involved, it may be worth removing and cleaning it at regular intervals.
