the air intake sensor measures the flow of air into the engine, it will be
located after the air filter, and before the intake manifold. i have a
feeling on this model it is located just after the air leaves the air box
where the air filter is.
regards.
Steve.

The Punto almost certainly uses SPI (Single Point Injection)

The injection unit will resemble a traditonal carburettor style housing on
top of the inlet manifold.

As far as I can remember SPI units in Fiats do not measure air flow as such.
They measure air intake temperature, RPM, throttle position etc. and the
fuel pulse is calculated on the fly.

I would research further for you but at this point in time I have business
commitments that I need to serve first.
