Product Details

The Walker Products 225-1019 MAP sensor measures intake manifold pressure so the engine control module can calculate load, fueling, and timing inputs more accurately. For Cadillac Allante, Eldorado, Seville, and DeVille applications, correct MAP sensor operation is important for stable drivability and consistent engine response. Walker Products backs its engine sensor line with in-house manufacturing, engineering, and technical support focused on accurate vehicle applications and OE-level specifications.

This part cross-references Standard Ignition AS37 for the same application.

Common Issues This Part May Address

• Rough idle caused by incorrect manifold pressure readings
• Hard starting related to inaccurate engine load input
• Hesitation or poor throttle response during acceleration
• Fuel mixture problems from faulty MAP sensor data
• Check engine light concerns tied to MAP sensor circuit faults

Installation Notes and Tips

Verify the connector shape, terminal count, and terminal gender before installation. Inspect the vacuum source, wiring, and connector terminals for damage or contamination before replacing the sensor. After installation, clear diagnostic trouble codes and confirm that live data readings are stable during idle and under load.
