Front air vent sensor?????
 

Bit trcky to explain.
Open the bonnet.Down to the left,black plastic air duct that looks like it's part of the induction set up.Should it have a wire/sensor plug into it?
Hey i tried.

Urmm, guessing its the MAF. Mass airflow sensor.

Think it depends on which MY it is. Mine (MY97) had a small black sensor where you describe. Where the air is drawn in above the n/s head light. Think it measures incoming air temp.

yep that's the one.Mines missing,well the sensor is but the loom end plug is still there.Guess it's either inactive or taking a reading from more or less the same place i.e just above o/s headlight.
Thanks for your help

I'd be inclined to investigate or replace it, as presumably, the ecu uses this sensors reading.

Yep will do.It's a shame the search option has gone down,ah well.

If you don't know what it looks like, PM you e-mail and I'll send you a pic of it.
