Show original supplier description
The TRQ ESA94889 is an OE replacement manifold absolute pressure (MAP) sensor designed to restore proper engine performance and fuel efficiency. This sensor is a direct fit, intended to function like the original equipment. The MAP sensor measures manifold pressure, providing critical data to the engine control unit (ECU) for calculating fuel injection timing and ignition timing adjustments. This sensor is compatible with a wide range of Buick, Chevrolet, GMC, and Pontiac vehicles, including the Buick Century (1982-2004), Buick Regal (1984-1985, 1988-1996), Buick Rendezvous (2002-2003), GMC C2500 (1984-1998), and Pontiac Grand Prix (1986-2003). It also fits models like the Chevy Camaro (1982-1997) and Oldsmobile Silhouette (1990-1994, 1996-2004), among others. The exact fitment list can be found by checking the specific compatibility information for your vehicle. As an OE replacement, the TRQ ESA94889 is engineered for direct fit and function, mirroring the specifications of the original part. Installation typically involves replacing the malfunctioning sensor, and no special tools beyond standard automotive hand tools are usually required. Ensuring the correct MAP sensor is installed is vital for optimal engine operation, preventing issues like rough idling, poor acceleration, and increased emissions.
