Detailed Product Overview

This Vemo MAP sensor is used to measure manifold pressure so the engine control module can calculate load, fueling, and ignition strategy more accurately. It is listed across a broad range of GM platforms, including Buick Lucerne, Cadillac DTS, Chevrolet Silverado 2500 HD, GMC Yukon, and Pontiac Grand Prix, making it a practical replacement for many late-1990s through 2011 vehicles. The V51-72-0091 part number is also referenced against Standard Ignition AS59 for the same application.

What This Sensor Helps Address

• Erratic idle caused by inaccurate manifold pressure readings
• Reduced engine performance from faulty MAP sensor input
• Check engine light related to pressure sensor circuit faults
• Hard starting or poor throttle response tied to incorrect load calculation
• Fuel mixture issues caused by unreliable intake pressure data
