Bosch Manifold Absolute Pressure MAP Sensor

The Bosch Manifold Absolute Pressure (MAP) Sensor, also called a manifold pressure sensor or MAP sensor, measures the pressure inside the intake manifold. It sends that reading to the engine control unit (ECU) as an electrical signal. The ECU uses the signal, together with other sensor inputs, to calculate engine load and air mass. It then adjusts fuel delivery and ignition timing to match.

Key Features:

• Measures absolute intake manifold pressure and sends a signal to the engine control unit
• Supports accurate fuel metering and ignition timing for efficient combustion
• Helps maintain smooth idle, steady drivability and good fuel economy
• Helps keep emissions within the engine's design limits
• Made to Bosch quality standards for dependable, long-term operation in under-hood conditions
• Direct-replacement design for straightforward installation

A failing MAP sensor can cause a rough idle, hesitation, poor fuel economy, black smoke or a check engine light. Replacing it with a Bosch sensor helps restore proper engine management.
