Standard Ignition Manifold Absolute Pressure Sensor P/N:AS453
Standard Ignition AS634 manifold absolute pressure sensor for the 2021-2024 BMW 228i Gran Coupe 4-cylinder 2.0L and other vehicles reads manifold pressure for the powertrain's electronic control unit. It is specifically engineered for BMW and Mini vehicles.
A failing sensor can show up as a rough idle, hesitation or poor fuel economy, though other faults can produce similar symptoms. Before replacing it, look over the connector and vacuum port with the engine off for cracks, damage or a loose fit. Each engine takes one sensor, and this listing is one.
It is listed for a wide range of BMW and Mini models, including the 2021-2024 BMW 228i Gran Coupe 4-cylinder 2.0L, the 2020-2024 BMW 228i xDrive Gran Coupe 4-cylinder 2.0L and the 2020-2024 BMW M235i xDrive Gran Coupe 4-cylinder 2.0L. Owners of other BMW or Mini models can look up their car's year and engine in the "Vehicles it fits" section.
