step -by -step

I have a fiat siena year 1999 full injection I want to know that the Speaker has step by step is the Q in the air journey where it accelerates I think that it works as a solenoid valve opens and closes an air of air and I know that it is damaged because I disconnect the cables and keep working I thank the person who knows of this sensor so that it helps me and I am well detailed.

To eat it is not a sensor but actuator, and it is called the valve or motor by step by step, in your vehicle especially you have installed iac valve of the Magnety Marely type, it is a enough one that comes out and enters an inner channel inside the admission body, this vasto has a route of approximately 8 mm, it is responsible for maintain These valves can be removed and clean two screws that affirm the body unless you have the Fire system that is a complete set included TPS, you take it clean its accommodation, disconnect the battery a minute you connect it and play 5 times to open and close the contact with a period between 15 seconds turn later and the Relay deveria deveria to stabilize, luck.

Hello if you disconnect it and continue the same may be that this iac valve already spoiled but it can also be dirt and is stuck and its return resort is stuck, so when it is disconnected it remains the same, it will be an electric valve but its work is mechanical you understand it has a solution

with
a
good clean They are already calibrated with an initial exit measure that is inscribed in the same IAC valve for that reason to the cleaning and put again
unintentionally you can unfold your engine
you have it with a mechanic of your trust

Thanks for the help, it will be that this valve can be burned since I can get it and provide the contacts are four pins and observe that there is no continuity between them or is normal
