Keep the engine control module reading intake manifold pressure accurately with the Standard Ignition Manifold Absolute Pressure Sensor AS495. It installs as a direct-fit replacement for the 2014-2018 BMW 328D and 328D XDRIVE, the 2014-2016 BMW 535D and 535D XDRIVE, the 2015 BMW 740LD XDRIVE, and the 2014-2015 BMW X5.
A manifold absolute pressure sensor measures the absolute pressure inside the intake manifold and sends that reading to the engine control module, which combines it with other inputs to help calculate air density and set fuel delivery and timing.
- Function: monitors intake manifold pressure and reports it to the ECM for load and fueling calculations.
- Direct fit: designed to install in place of the original sensor on the listed BMW applications.
- Signs it may need replacing: rough idle, hesitation, poor fuel economy, or an illuminated check engine light — if a failed MAP sensor is the cause. Diagnose the cause before replacing.
Interchange: Manufacturer part number AS495.
