Bosch LR021587 Air Temperature and Manifold Pressure Sensor (TMAP)

The Bosch LR021587 is an air charge temperature sensor that includes turbocharger boost sensor functionality, commonly referred to as a TMAP (Temperature Manifold Absolute Pressure) sensor. This dual-function sensor is designed to read both manifold absolute pressure (MAP) and intake air temperature (IAT) in a single compact unit, providing instantaneous manifold pressure information to the engine's electronic control unit (ECU).

Key Features:

• Genuine Bosch OEM quality sensor used in Land Rover vehicles worldwide
• Dual-function design measures both intake air temperature and manifold absolute pressure
• Mounts at the engine intake manifold location
• Supersedes part number LR008887
• Essential for proper engine performance and fuel management

This sensor fits multiple Land Rover models including Defender 110, Defender 90, Discovery, Discovery Sport, LR2, LR4, Range Rover, Range Rover Evoque, Range Rover Sport, and Range Rover Velar across various engine configurations including 2.0L, 3.0L V6, and 5.0L powerplants. The TMAP sensor enables the ECU to make precise fuel delivery and boost pressure adjustments based on real-time temperature and pressure readings from the intake system.
