MAP = Manifold absolute pressure and is a sensor to measure vacuum, the computer calculates the engine air flow based on the vacuum, throttle position, and intake air temperature. The computer also measures the barometric pressure using the MAP sensor before the engine cranks, this lets the computer compensate for altitude, or how dense the air is. Typical ...

Also, remember that MAF is a reading of the amount of air entering the engine. If you have a backflow issues (high backpressure) or even a timing issue where the valves are not opening and closing at the correct time (slack chains, jumped timing), your MAF sensor readings will reflect this as well. I know this post is late, but any who are looking into this ...

Do you have a source for that formula? Is it possible that you are reading Calculated engine load value, which would indeed be zero when you are in neutral? Range: 0 to 100 Units: % Formula: A*100/255 I did find this page which defines it as: Calculated Load Value -- Indicates a percentage of peak available torque. Reaches 100% at wide open ...

I think you misunderstand the purpose of the Mass Air Flow (MAF) sensor (and whoever wrote what you read doesn't understand, as well). The purpose of the MAF is to read the amount of incoming air. As the incoming air flows over the heated sensor, it cools the sensor which regulates the amount of electricity which can flow through it. It is in no way ...

The Peugeot 207 petrols have a little bit of a reputation for clogging up on the throttle body. Using a tin of throttle body cleaner and a common bath room tooth brush, remove the hose to the throttle body. Spray in and around the throttle and clean off any 'dirt' with the tooth brush. Hold the throttle blade open and clean as much as possible in and around ...
