Hi all,

I understand that the MAP sensor has the IAT sensor built in. I have a fault code for the IAT, Could anyone advise which wires are for the IAT sensor ??

The colours are: Brown, light purple, White, Blue.

I'm new to forums, so please excuse for not introducing myself, is there a place to do so ?

thanks in advance.

Hi Painterman,

No need for introductions.

Unfortunately I don't know the wiring for the MAP/IAT (Manifold Absolute Pressure)/(Intake Air Temperature) sensors. But;

The units are an easy removal and refit and cost only about £20.

My thoughts are, even if you did know the wiring, will you be able to interpret the data from the MAT to the ECU? to diagnose a response.

Swapping the MAT out for a known working one can save a lot of time in faulting the MAT itself.

But, as always, check the obvious stuff first, like the air filter.

Sorry I didn't answer your question directly (or even at all!)
