Hitachi MAF0122 Mass Air Flow Sensor

Hitachi MAF0122 Mass Air Flow Sensor

Hitachi MAF0122 is a mass air flow sensor for select Honda and Acura applications, including Honda Accord, CR-V, Odyssey, Pilot, Ridgeline, and Acura MDX. It measures incoming air volume and air characteristics so the engine control system can maintain accurate fuel delivery and emissions control.

Key Features

• Precision sensing elements for accurate air flow measurement
• Calibrated for each application for OE-style signal output
• Protected circuitry for added durability in engine-bay conditions
• Air flow tested for performance verification before release
• OE-approved design approach for direct replacement use

Detailed Overview

Built by Hitachi, part number MAF0122 is engineered for vehicles that rely on precise intake-air measurement to manage drivability and emissions. This sensor is used across a wide range of Honda and Acura models, including 2018-2022 Honda Accord, 2020-2022 Honda CR-V, 2019-2025 Honda Odyssey, and 2022-2025 Acura MDX. It also cross-references Standard Ignition MAS0423 for the same application. By matching the vehicle’s calibration requirements, the sensor helps the engine computer respond correctly to changing airflow conditions.

Hitachi uses quality components and application-specific calibration to support consistent readings. The design includes protected circuitry and, where applicable, a contaminant bypass port to improve durability. For shoppers searching for a Honda Accord mass air flow sensor, Acura MDX MAF sensor, or a direct-fit replacement for Honda Pilot and Ridgeline models, MAF0122 provides an OE-style solution.

Common Issues This Part Can Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or poor throttle response during acceleration
• Check engine light related to mass air flow sensor faults
• Incorrect fuel trim from a contaminated or failing sensor
• Reduced drivability on Honda and Acura vehicles with intake-air measurement errors

Installation Notes and Tips

Verify the connector style and terminal type before installation; listed applications use blade terminals. Inspect the intake tract for leaks, dirt, or oil contamination that can affect sensor readings. Clear diagnostic trouble codes after replacement and confirm the repair with a road test and scan tool data review. Use the exact vehicle application match for 2010-2025 Honda and Acura models to ensure proper fitment.

Quality Assurance

Hitachi tests each MAF for air flow performance and calibrates it by application to support accurate operation. The brand’s OE-focused manufacturing approach and protected circuitry help deliver a reliable replacement for emission control service on Honda and Acura platforms.
