Bosch 0091538628 Manifold Absolute Pressure MAP Sensor

The Bosch 0091538628 is a precision-engineered Manifold Absolute Pressure (MAP) sensor designed to deliver accurate intake manifold pressure readings to the engine control unit (ECU). As a critical component of the engine management system, the MAP sensor enables the ECU to calculate the correct air-fuel mixture and optimize ignition timing for efficient combustion.

Bosch is the world's largest supplier of original equipment (OE) automotive sensors, and this MAP sensor is built to the same exacting standards as the sensors installed on vehicles at the factory. It provides a reliable, direct-fit replacement that restores proper engine performance and fuel economy.

Key Features:

• OE-quality construction engineered and manufactured by Bosch
• Provides precise manifold absolute pressure signal to the ECU
• Supports accurate air-fuel ratio calculation and ignition timing
• Built to meet or exceed original equipment specifications
• Resistant to heat, vibration, and engine bay contaminants
• Direct-fit replacement for straightforward installation

A faulty MAP sensor can trigger check engine lights, cause rough idling, poor acceleration, increased fuel consumption, and failed emissions tests. Replacing a worn or failed sensor with a genuine Bosch unit helps restore proper drivability and engine efficiency.
