In Topic: The Button I Never Use??????

Thanks fellas for all the replies on the button. I guess I will use it more in summer time but can always use it to keep out those diesel fumes and smells from the outside lol!

engines were much better before 2005 on most manufacturers definitely before 2002 on all manufacturer's
only one oxygen sensor in exhaust and a catalyst.
some had map sensor others had a MAF
proper distributor cap and HT leads no coil packs,
Cars had LSD instead of ESP
Turbos had bleed valves instead of EGR Valves
DPF's didn't exist.

Totally agree with you Lenny. It be interesting to see what its like in 10 years times.  :)

Technically the measure the same thing but interpreted differently.

By running an electrical current through a wire you know how hot it is, by changing that temperature you alter the voltage due to resistance, with some Maths you can work out what the temperature is and or how much air is flowing past it, if its covered in crap it will reduce the effect of air temp so buggers up the readings to the ecu

Thanks Darren, Great Info there. Its amazing the way that the sensors are designed on modern engines and how it all works together compared to the older engines back in the day.

Sonic, your right about the MAF, the TMAP sensor sits in the inlet manifold and measures the intake air temp and the manifold vacuum.


Temperature and Manifold Absolute Pressure (T-MAP) sensor


Well I'm glad I'm on the right tracks there lol! Can the TMAP sensore be cleaned using special cleaner and if so what one is best? also is there any way to test the TMAP sensor the same way that a MAF can be tested.

whats the difference between a MAF and a TMAP?

You don't have a MAF,  Focus Petrol engines from 2002 use a TMAP sensor.

Does the MAF measure the amount of the air going through and the TMAP measure the Temperature of the air going through?


Just wondering as its always good to know these things lol!
