The intake manifold pressure sensor — also called the MAP sensor, manifold absolute pressure sensor, or boost pressure sensor — measures the pressure inside the inlet manifold and reports this to the ECU to set fuel injection quantity and ignition advance. On turbocharged engines it tracks boost pressure as well as vacuum. A faulty Sensor, intake manifold pressure causes incorrect fuelling, limp-home mode, and failed emissions tests. CarParts247 stocks OEM and aftermarket intake manifold pressure sensors from Bosch, Continental, Hella, and Siemens VDO for a broad range of naturally aspirated and turbocharged engines.
The sensor contains a piezo-resistive element that flexes in response to pressure changes, producing a voltage output that varies linearly with manifold pressure. At idle on a naturally aspirated engine, manifold pressure is low (high vacuum); under full load it approaches atmospheric. On turbocharged engines it rises above atmospheric at boost.
A drifting or failed MAP sensor causes the ECU to use incorrect load values for every injection and ignition calculation, affecting everything from idle to full-throttle performance.
MAP sensors are usually mounted directly on the intake manifold or connected by a short vacuum hose. Replacing the sensor is a simple plug-and-play operation in most cases. If the sensor uses a vacuum hose, inspect the hose for splits before assuming the sensor is at fault — a cracked hose causes exactly the same symptoms.
