What Is a MAP Sensor?
The MAP sensor helps your engine fuel correctly under load. A Cranbourne West specialist explains.
What it is & what it does
The MAP (manifold absolute pressure) sensor measures the pressure in the intake manifold, telling the computer the engine load (and, on turbo cars, the boost) so it can set the right fuel and timing. Many engines use it alongside or instead of a MAF sensor.
It’s key to correct fuelling, especially under load.
Signs of trouble & how we help
A faulty MAP sensor causes hesitation, poor economy, rough running, black smoke, or a check-engine light — symptoms similar to a MAF fault. On turbo cars it affects boost control.
We read live MAP data to confirm the sensor before replacing it.
