Porsche Manifold Absolute Pressure Sensor - Genuine Porsche 9A790605201

Product Information

A Manifold Absolute Pressure (MAP) sensor is an essential component in a vehicle's engine management system. It measures the pressure inside the intake manifold, providing data to the engine control unit (ECU) to help calculate air density and determine the correct air-fuel mixture. This information is critical for optimal engine performance, fuel efficiency, and emissions control.

• Check Engine Light: A malfunctioning MAP sensor often triggers the check engine light, indicating a potential issue with the engine management system
• Poor Engine Performance: If the MAP sensor fails, it can lead to reduced engine power, sluggish acceleration, or hesitation during driving due to an incorrect air-fuel mixture
• Rough Idle: A faulty MAP sensor may cause the engine to idle roughly or inconsistently, often leading to stalling or difficulty starting the engine

About Genuine Porsche

The original parts used by Porsche to build your car are available as replacement parts under the “Genuine Porsche” brand. Manufactured under the direction of Porsche, expect excellent quality and a premium price since these parts are exclusively available through the Porsche Dealership network.

You may not realize this, but the parts that make up your Porsche are not necessarily manufactured by Porsche. No cause for concern, as Porsche designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Porsche for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine Porsche parts box and find an OEM branded part inside, simply with the addition of a Porsche logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
