ACDelco Fuel Injection Manifold Pressure Sensor

The ACDelco Fuel Injection Manifold Pressure Sensor, also called a MAP sensor or manifold absolute pressure sensor, measures the pressure or vacuum inside the intake manifold. It sends that reading to the engine control module (ECM). The ECM uses the signal, along with other inputs, to calculate engine load and air density. It then adjusts fuel delivery and ignition timing for efficient combustion.

Key Features:

• Gives the engine computer accurate intake manifold pressure data for fuel injection control
• Helps maintain smooth idle, steady throttle response and good fuel economy
• Helps keep emissions within design targets
• Built by ACDelco, General Motors' parts brand, to meet demanding quality and durability standards
• Designed for reliable electrical performance and resistance to heat, vibration and under-hood conditions

A failing MAP sensor can cause a check engine light, rough idle, hesitation, poor fuel economy or hard starting. Replacing it with a quality ACDelco sensor helps restore proper engine management and drivability. Pick the child item that matches your application.
