AAV constantly on

[UKjarvis]

Hi noticed that my auxillery air valve never shuts off, dont think its normal if anyone has any idea of the cause that would be gr8.  1.8 8v kjet.

erm...

This item is a device to aid the engine when cold by opening a small port to increase the engine's idle speed. The fast idle control is achieved by the port being held open by a bi-metalic strip that when heated by it's own heater element, or via natural heat soak from the engine, the port closes. The voltage supply to the air valve is the same as the feed to the fuel pump and the warm-up-regulator. If it is found that the idle speed will not reduce and that the speed is maintained artificially high when warm, clamp the rubber pipe between the air valve and the inlet manifold. If this action causes the engine rev's to return to normal, the fault is within a sticking auxiliary air valve.
It is worth cleaning the valve, lubricating it and re-test it's operation. The internal heater element can also be checked for continuity using a multimeter.

Hope this helps, especially the end bit

aye this should get 12v whenever the fuel pump is on

appears to be sticking, il investigate fully 2moro.

Good work my man, not sure about the AAV but the ISV takes a good saturation of carb cleaner followed by a quick jizz of WD40
