GM GENUINE PARTS MAP Sensor replacement 213-4760 (55567257) – OE fit, engine control accuracy

The GM Genuine Parts 213-4760 (55567257) Manifold Absolute Pressure (MAP) Sensor accurately measures intake-manifold pressure to help your engine control module determine proper fuel delivery.

This replacement MAP sensor is engineered to match the original equipment specifications for compatible General Motors vehicles. It interfaces with the engine control module and works alongside throttle position data to estimate incoming airflow, allowing fuel injection to be adjusted for efficient combustion. Built to GM OE standards, this unit aims to deliver the same fit, function, and durability as the factory-installed component.

How does this MAP sensor affect engine performance?

The sensor provides real-time manifold pressure readings that the vehicle’s control systems use to estimate air mass and optimize fuel injection. When the MAP sensor reports accurate data, the engine control module can better balance fuel and ignition timing, which supports consistent drivability.

• Supplies pressure signal used by the ECM for air/fuel calculations
• Works with throttle position input to estimate airflow
• Helps maintain stable idle and throttle response under varying loads

Will this GM Genuine Parts unit fit my vehicle and match factory performance?

Yes — the 213-4760 (55567257) is manufactured to GM’s original equipment specifications and intended as a recommended replacement for the factory-installed MAP sensor. It is designed to match the vehicle’s original fitment, electrical connector, and signal characteristics for straightforward integration.

• GM-recommended replacement for the original factory component
• Engineered to OEM tolerances for reliable fit and signal output
• Durability and materials aligned with GM OE quality standards

What installation or setup steps should I expect?

Installation often requires more than a simple plug-in; some vehicles need programming or special setup to ensure the new sensor communicates correctly with the vehicle’s control modules. Refer to GM Service Information for the specific calibration procedures and any diagnostic tools required.

• May require programming or special setup procedures
• GM Service Information lists tools and step-by-step instructions
• Use authorized diagnostic tools to confirm proper operation after install

How can I confirm the sensor is working after replacement?

After installation, run the vehicle’s onboard diagnostics and monitor live MAP readings to verify expected pressure values at idle and under load. A stable, responsive signal that changes with throttle input and load indicates the sensor and vehicle calibration are functioning properly.

• Check live MAP values with a scan tool at idle and during throttle changes
• Verify absence of related diagnostic trouble codes (DTCs)
• Confirm improved fuel trim and stable idle behavior

Who is this for: Technicians, repair shops, and GM owners seeking a direct OE-quality replacement for a failing or suspect MAP sensor will benefit from the GM Genuine Parts 213-4760 (55567257). It’s intended for vehicles that require authentic GM fitment and performance and for installations where proper programming and diagnostic verification are available.
