Hyundai Accent 2001 1.5cc

Well, if you have a scam, look at the air flow in this one has to be + or - in 1.8 v in vel. I slow down, if you have bosiloscope, look at the signal if it is not cut when you accelerate.
If you can very carefully carefully the sensor with a soft solvent porke if you do not damage
look to see Sieste has no dirt in the elfilamentob ke brings
I hope this helps you this.

Thank you for the help, but I don't know what is the bosiloscope sensor and you recommend me.

The same thing happened to me and it was a broken cable of the connector of the minimum valve sold it and voila.
