NTK MA0091 Manifold Absolute Pressure Sensor (MAP Sensor)

The NTK MA0091 is a direct-fit Manifold Absolute Pressure (MAP) sensor engineered to OE specifications by NTK — the sensor division of NGK Spark Plugs. This replacement MAP sensor restores accurate intake manifold pressure monitoring to your vehicle's engine management system.

How It Works:

The MAP sensor continuously measures intake manifold pressure and vacuum, sending a voltage signal to the Engine Control Module (ECM). The ECM uses this data to determine engine load and calculate the correct air/fuel ratio and ignition timing for optimal combustion efficiency.

Key Features:

• Direct OE replacement — meets or exceeds original equipment fit, form, and function
• Manufactured by NTK, an OE supplier with over 80 years of automotive expertise under the NGK group
• Engineered and tested to withstand thermal shock, vibration, and OBD verification
• Helps restore proper fuel metering, ignition timing, and manifold pressure readings
• Sold individually; wiring harness not included

Common Replacement Symptoms:

• Check engine light illumination (MAP-related DTCs)
• Engine hesitation or rough idle
• Poor fuel economy
• Failed emissions tests
• Engine stalling or extended crank time

The NTK MA0091 MAP sensor may be mounted in the intake manifold, throttle body, or remotely under the hood depending on the application. Trust NTK — The Sensor Specialist — for premium aftermarket sensor coverage backed by genuine OE manufacturing experience.
