MAP Sensor Manifold Absolute Pressure Sensor 12569240 Replacement for Chevrolet/GMC/Buick/Pontiac/Cadillac/Oldsmobile 1982-2004 Suburban 1500 S10 Camaro Trans Am Grand Prix Cavalier by AUTOMAJOR

The AUTOMAJOR MAP Sensor (Manifold Absolute Pressure Sensor) is a direct OEM replacement designed for GM vehicles spanning two decades. This sensor measures the absolute pressure inside the intake manifold and sends the signal to the ECU (engine computer), which uses the data to calculate engine load, control fuel injection timing, and adjust ignition timing for optimal performance and fuel economy. This sensor replaces GM OEM 12569240. Cross-references with 16137039, 16254719, 16158055, 2131545 (213-1545), 5S2397, 2MAP0005, AS5T, MP102, F00099P169, 3933024750, AS5, 1580380, 2251001, MA0089, PS10075, 103001, and V40720323. If your vehicle uses any of these part numbers, this sensor is the correct replacement. The MAP sensor is mounted on the intake manifold or near the throttle body. It uses a pressure-sensitive diaphragm to measure manifold vacuum/pressure and converts the reading to an electrical signal sent to the ECU. The ECU compares this data against engine RPM and other sensor inputs to determine the precise amount of fuel needed for current engine load. A failed MAP sensor causes incorrect fuel mixture calculations — leading to drivability problems and emission issues. Common symptoms of a failed MAP sensor include: check engine light with codes P0068, P0069, P0105, P0106, P0107, P0108, P0109, rough idle and stalling, hesitation or stumbling on acceleration, poor fuel economy (engine runs rich), black smoke from exhaust, lack of power under load, hard cold start, surging at steady throttle, failed emissions test, and engine misfire codes that disappear after MAP sensor replacement. Replacing the MAP sensor is a 15-30 minute DIY job. Tools needed: 8mm or 10mm socket (depending on application), ratchet, screwdriver, and shop towels. Procedure: locate the MAP sensor on the intake manifold or near the throttle body (small electrical sensor with 3-pin connector and either a vacuum hose or direct manifold mounting), disconnect the electrical connector, disconnect the vacuum hose if equipped, remove the mounting bolt(s), pull the sensor straight out, install the new AUTOMAJOR sensor in the same orientation, reconnect the vacuum hose to its original port, install mounting bolt(s) and torque to specification (typically 7-9 ft-lbs / 10-12 Nm), reconnect the electrical connector, start the engine and verify smooth idle, clear any stored diagnostic codes. This sensor fits Chevrolet Suburban 1500/2500 (1988-2000), Tahoe (1995-2000), Silverado 1500/2500/3500 (1988-2000), C/K 1500/2500/3500 (1988-2000), Astro (1988-2005), Blazer (1988-2005), S10 (1988-2004), S10 Pickup (1988-2004), Cavalier (1988-2002), Camaro (1988-2002), Corsica (1988-1996), Beretta (1988-1996), Lumina (1990-2001), Monte Carlo (1995-2007), Impala (2000-2005), Malibu (1997-2003), Caprice (1991-1996); GMC C/K 1500/2500/3500 (1988-2000), Yukon (1992-2000), Suburban 1500/2500 (1992-2000), Sierra 1500/2500/3500 (1988-2000), Jimmy (1988-2005), Sonoma (1988-2004), Safari (1988-2005), Envoy (1998-2009); Pontiac Trans Am (1990-2002), Firebird (1990-2002), Grand Prix (1990-2008), Grand Am (1990-2005), Bonneville (1992-2005), Sunfire (1995-2005), Sunbird (1988-1994); Buick Regal (1988-2004), Century (1988-2005), LeSabre (1992-2005), Roadmaster (1991-1996), Park Avenue (1991-2005), Skylark (1990-1998), Riviera (1995-1999); Cadillac DeVille (1990-2005), Eldorado (1990-2002), Seville (1990-2004), Fleetwood (1991-1996), Escalade (1999-2000); Oldsmobile Cutlass (1988-1999), 88/98 (1990-1999), Aurora (1995-2003), Bravada (1991-2004), Silhouette (1990-2004), Intrigue (1998-2002); Hummer H2 (2003-2007).

• The MAP sensor measures the absolute pressure inside the intake manifold and sends the signal to the ECU. The ECU uses this data along with engine RPM to calculate the precise amount of fuel needed for current engine load. A failed MAP sensor causes incorrect fuel mixture calculations — leading to drivability problems and emission issues across the engine RPM range.
• Symptoms of a failed MAP sensor: check engine codes P0068, P0069, P0105, P0106, P0107, P0108, P0109, rough idle and stalling, hesitation or stumbling on acceleration, poor fuel economy (engine runs rich), black smoke from exhaust, lack of power under load, hard cold start, surging at steady throttle, failed emissions test, engine misfire codes that disappear after MAP sensor replacement.
