Mercedes-Benz Wittig reports that the hot film air quality sensor is not credible compared with the throttle position.

Hello, according to your description, you can use the diagnostic computer to read the related data streams of these two. If the throttle opening is within the normal range, but the air flow is small, then there is the throttle opening caused by our recent pipeline leakage. Not normal, but the air intake is normal. That may be a problem with our sensor. I suggest you analyze the data, and then check and judge the fault with a multimeter. I hope it helps you.
