It read the temp

Nah seriusly, it makes sure that if the temps get over 69 degrees, because if it does it will retard the ignition and you will loose power. Kind of a safety device. That is why you (should) fit a better intercooler so the temp's never get that high... and with lower temp's come more bhp.
And that's because cold air takes up less space than warm air. And the more air you can get in chamber the more fuel you get in and = more bhp.

Correct me if im wrong people.

 

that sums it up pretty well!

 

So if this was faulty do you think this could cause a top end misfire. When my car hits around 5300rpm it goes lean and totally misfires and wont go any further.

 

i brought a new sensor for mine, they int cheap, it did make a difference, when you look at the old one it had been in there for years!!.

 

It helps with the speed density calculations and is a very important part of teh system in Any EFI Turbo car.

Bosh KE uses it less than most others but its still very important and should never be neglected.

 

Thanks people will have a look at this
