LOL i cant find where it is located...

Please help!!!

I think it is in the AFM.

in the afm, it's big less than 2mm and has 2 little wire keeping it, it's on the afm intake before the flap

hummm will take a part and take pics hopefully fix!

Now how to fix and test..!

Found this... From here... http://opel-scan.ru/files/DME_1.1_1.3.pdf

ATS
The ATS is mounted in the AFS inlet tract and measures the air temperature before it enters the inlet manifold. Because the
density of air varies in inverse proportion to the temperature, the ATS signal allows more accurate assessment of the volume of
air entering the engine. However, the ATS has only a minor correcting effect on ECU output.
The open circuit supply to the sensor is at a 5.0 volt reference level and the earth path is through the AFS earth return circuit.
The ATS operates on the NTC principle. A variable voltage signal is returned to the ECU based upon the air temperature. This
signal is approximately 2.0 to 3.0 volts at an ambient temperature of 20� C and reduces to about 1.5 volt as the temperature rises
to around 40� C.

Anyone have any knowledge on this?

This is probably not much help to you, but you are probably better off just replacing the AFM. You can test the ATS by finding the pins on the AFM that it connects to and then get a hair dryer and blow it at the sensor while reading the restance, but what do you do about it? It's probably faster and cheaper just to replace the whole AFM and be done with it.

True true true but im a tool so ya know i have to try

and the code number is code 77 in the verus and 1224 for the stomp test.
