ACDelco GM Original Equipment Fuel Injection Manifold Absolute Pressure Sensor

The ACDelco GM Original Equipment Manifold Absolute Pressure (MAP) Sensor is a fuel injection sensor that measures pressure or vacuum in the intake manifold. It sends that reading to the engine control module (ECM/PCM). The ECM uses the signal, along with other inputs, to calculate engine load and adjust fuel delivery and ignition timing. Accurate MAP readings help the engine run smoothly, respond well, use fuel efficiently and keep emissions low.

Key Features:

• GM Original Equipment design from ACDelco, GM's parts brand
• Gives the engine control module accurate intake manifold pressure data for fuel and spark control
• Helps maintain drivability, fuel economy and emissions performance
• Built to meet GM standards for fit, function and durability
• Direct-replacement design that simplifies installation

A failing MAP sensor can cause a check engine light, rough idle, hesitation, poor fuel economy or a loss of power. Replacing it with a GM Original Equipment sensor from ACDelco helps restore proper engine management. Each part number in this product line is engineered for its specific application.
