I have a Hyundai Accent 1.3I LS, which is equipped with a MAF (flowmeter) Bosch F 00c 2g2 042. It seems to be an admission air temperature detector by means of a diod, a metal sheet I imagine for the density, and a body with two sensors and a tiny heater, within a design that seems to improve the stability of the measurement.
The symptom is when it accelerated thoroughly, the car simply lost speed. If I disconnect the connector flowmeter, it goes from fable, but in the emission control the monoxide triggered appears, and a high percentage of fuel non -burned, in reling above all. The fault indication is turned on.
I clean the flowmeter properly, and now when I start, the check does not appear, if the engine is cold, and the operation is quite good. If I start it hot, I can't slow down, but the operation is quite good.
The measures of the 5V switchboard value, of the value of thermal compensation 3.5-3-2V, OK, but I have a fixed value of 6.9V in PIN 1 and a 0V in PIN 4, when the common (Pin 3) is already 0V, so that my doubt is whether it needs an additional electrical circuit signal by PIN 4 and what value it has to be.
All the best.
Santiago.
