Genuine LR187422 Manifold Absolute Pressure (MAP) Sensor, Supercharger Boost Pressure Sensor

The Genuine LR187422 is a manifold absolute pressure (MAP) sensor, also called a supercharger boost pressure sensor. It is a genuine Land Rover part.

Key Features:

• Manifold absolute pressure sensor, also listed as a MAP sensor
• Supercharger boost pressure sensor
• Mounts at the supercharger

A MAP sensor measures pressure in the intake system and sends that reading to the engine control unit. The engine control unit uses it to manage engine operation. Replacing a faulty sensor helps restore proper boost and intake pressure readings.
