Air & turbo
Manifold-pressure sensor
Measures air pressure in the intake system.
In the intake manifold or charge-air tract, depending on design.
Its electrical signal represents pressure; temperature sensing may share the same housing.
A pressure gauge reporting to the engine’s computer.
Implausible boost or load readings can arise from the sensor, connector or an actual air leak.
Filters follow the vehicle service schedule; ducts and boost hardware are inspected for condition, sealing and operation.
A hose or filter is generally simpler to service than a turbo assembly. Access and diagnosis can dominate cost.
Similar-looking BMW pressure sensors can have different measurement ranges and pin assignments.
BMW combustion models; boost hardware applies to turbocharged engines only.
