The boost pressure sensor — also called the MAP sensor, turbo pressure sensor, or manifold absolute pressure sensor — measures the pressure of charged air in the intake manifold or intercooler outlet and feeds this data to the ECU to control turbocharger boost and fuelling. A faulty sensor causes the ECU to misread boost levels, leading to reduced power, over-boosting, or limp-home mode. Sensor, boost pressure failures are particularly common on high-mileage turbocharged diesels where heat and oil mist contaminate the sensing element. CarParts247 stocks boost pressure sensors from Bosch, Continental, and Hella for a wide range of turbocharged petrol and diesel engines.
The ECU monitors boost pressure continuously. When the sensor reading deviates from expected values, the management system triggers codes and takes protective action.
Boost pressure sensors typically screw or clip into the intake manifold or intercooler pipe. Disconnect the wiring connector, unscrew or unclip the old sensor, and fit the new unit. Smear the O-ring lightly with fresh engine oil to prevent tearing during installation. Clear fault codes and perform a test drive to confirm boost pressure readings are within specification.
Always inspect the wiring harness for chafing or heat damage before condemning the sensor — intermittent boost-pressure faults on turbodiesels are frequently caused by damaged wiring rather than a failed sensor.
