What is the MAF sensor reading under no load?

The mass air flow (MAF) sensor reading under no load conditions is typically low, as the engine is not requiring as much air input to maintain operation. In most cases, a reading around 0.85 volts is a standard value for MAF sensors when the engine is idling and under light load conditions.

This low voltage indicates that the engine management system is receiving data that reflects a reduced air intake, consistent with no load. The MAF sensor measures the flow of air entering the engine, and under no load, the amount of air flowing through the intake is minimized.

Higher readings, such as those approaching 1 volt or above, would be more common during acceleration or under a load situation when the engine demands more air. Therefore, a reading of 0.85 volts represents an appropriate and expected value for idle conditions where minimal load is placed on the engine, making it the most suitable choice for the question posed.
