It is engineered to meet or exceed OE specifications for fit, form, and function, helping restore accurate manifold pressure signal input to the engine control system.\u003c\/p\u003e\u003cp\u003eCompatible with applications such as Chevrolet Silverado, GMC Sierra, Tahoe, Yukon, and Cadillac Escalade models, this MAP sensor supports precise engine management across many 2008-2024 vehicles.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eManifold absolute pressure sensor for emission control and engine management systems\u003c\/li\u003e\n\u003cli\u003eOE-style fit, form, and function for direct replacement service\u003c\/li\u003e\n\u003cli\u003eDesigned for broad coverage on Chevrolet, GMC, Cadillac, Buick, Saab, Hummer, and Isuzu applications\u003c\/li\u003e\n\u003cli\u003eCross-references Standard Ignition AS394\u003c\/li\u003e\n\u003cli\u003ePart number MP144 for catalog and service identification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDetailed Description\u003c\/h2\u003e\u003cp\u003eThe Spectra MP144 MAP sensor measures intake manifold pressure and sends that data to the vehicle’s engine control module for fuel and load calculations. Accurate sensor output is important for drivability, throttle response, and emissions-related engine control. This part is a strong match for GM truck, SUV, and car platforms including Silverado 1500, Sierra 1500, Tahoe, Yukon, Camaro, Corvette, and Express van applications. If you are replacing a failing MAP sensor on a Chevrolet Silverado 2500 HD or GMC Sierra 3500 HD, MP144 provides a direct-fit service solution.\u003c\/p\u003e\u003cp\u003eThis part cross-references Standard Ignition AS394 for the same application. The MP144 designation is also useful when verifying service records or matching an existing sensor by part number.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRough idle caused by inaccurate manifold pressure readings\u003c\/li\u003e\n\u003cli\u003eHard starting or extended crank conditions\u003c\/li\u003e\n\u003cli\u003eReduced engine performance from incorrect load data\u003c\/li\u003e\n\u003cli\u003eCheck engine light concerns related to MAP sensor faults\u003c\/li\u003e\n\u003cli\u003eFuel trim and drivability issues tied to sensor signal errors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the connector style and mounting location before installation. Fitment varies by platform, and some applications place the sensor in the throttle body, air cleaner, or air cleaner pipe. Confirm the vehicle year, make, and model against the listed fitment before ordering. After installation, clear diagnostic trouble codes and confirm stable idle and sensor readings with a scan tool.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eSpectra states that this replacement sensor is built to meet or exceed OE specifications for fit, form, and function.\u003c\/p\u003e","brand":"Spectra","offers":[{"title":"Default Title","offer_id":44724447576245,"sku":"BCNK-MP144","price":82.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/SQ_MP144_Fro_47d54f6e-c100-42ba-a6ce-e6892788e773.jpg?v=1775096725","url":"https:\/\/www.partcatalog.com\/products\/spectra-mp144-manifold-absolute-pressure-sensor","provider":"PartCatalog","version":"1.0","type":"link"}
