The new Santa Fe clean throttle engine fault light comes on.

Just washed the throttle. The mixture will be too thick, so the computer will record that accidental failure. After driving to a certain distance, that situation will disappear, so the fault light will go out by itself. I don't believe you can read the fault code with a computer. It must be an accidental fault. The light should be an emission failure light. At the moment of ignition, the idle speed is almost 2000, which is reduced to 1000. I think it's still a little high. Generally, a four-cylinder engine is between 750 and 850.
