Bosch Turbocharger Boost Pressure Sensor

The Bosch Turbocharger Boost Pressure Sensor (also called a turbo boost sensor, manifold absolute pressure or MAP sensor, or charge pressure sensor) measures the air pressure in the intake or charge-air system of a turbocharged engine. It sends a signal to the engine control unit (ECU). The ECU uses that signal to regulate fuel delivery, boost control, and ignition timing.

Key Features:

• Accurately measures absolute pressure in the intake or charge-air system for precise engine management
• Built to Bosch's OE-quality standards for reliable performance across a wide temperature range
• Designed to resist vibration, heat, oil, and the other harsh conditions found in the engine bay
• Helps maintain proper air-fuel ratio, throttle response, and turbo performance
• Sealed housing and a robust electrical connector help protect signal integrity

A failing boost pressure sensor can cause reduced power, poor fuel economy, rough running, limp mode, or a check engine light. Replacing it with a quality Bosch sensor helps restore proper engine control and boost regulation. Bosch is a leading global supplier of automotive components and original equipment, known for its sensor technology and engineering quality.
