Failure on ARP4:

The engine starts but cuts off at acceleration.
The admission air opening is communicated to the ECU by a throttle switch more or less opened by the accelerator pedal.
Unfortunately the throttle switches are similar but are not identical, the only ones that work:
the variations in resistance measured between the connectors C B A must be as follows:
between C and B from 2.02 to 4.43 ohms
between B and A from 1.02 to 3.60 ohms
between A and C 3.83 and 3.83 ohms (fixed)
Bad

Correct

Thanks for the information API, I guess that would be either the throttle potentiometer (better known at the 'throttle pot') or just the plug for it?

Or perhaps more commonly known as the Throttle Position Sensor (TPS).

writing in English is hard for me, I am of course talking of the Throttle position sensor.
thank Peter.

Absolutely, thanks Peter, and your posts are much appreciatecd API, your English is more than good enough, wish my French was anywhere near as good.

Absolutely. My French is almost non existent much to my shame.
