• Includes 1 vacuum port for accurate pressure readings
• No hardware, mounting brackets, O-rings, or wiring harness included

Detailed Product Description

The Standard Ignition AS147 MAP sensor features a three-terminal design with male blade terminals that connect to a single female plug-in connector. Its black finish ensures resistance to environmental factors under the hood. The sensor includes one vacuum port, essential for measuring the absolute pressure inside the intake manifold. The connector shape is a combination of round and rectangular, providing a secure and reliable electrical connection. This sensor is engineered specifically for Mazda Miata and Millenia vehicles, ensuring compatibility and accurate data transmission to the engine control unit (ECU).

Common Applications and Issues Addressed

• Helps regulate air-fuel mixture for efficient combustion
• Prevents engine stalling and rough idling caused by faulty pressure readings
• Reduces emissions by providing accurate manifold pressure data
• Improves throttle response and overall engine performance
• Assists in diagnosing vacuum leaks or sensor malfunctions

Installation Notes and Tips

Installation of the Standard Ignition AS147 sensor requires no additional hardware or mounting brackets, as it is designed to fit directly into the existing manifold port. Ensure the connector is securely plugged in, matching the female plug to the male blade terminals. Since no O-rings or wiring harness are included, reuse existing components or source replacements as needed. Proper handling of the vacuum port is essential to maintain sensor accuracy and prevent leaks.
