Hitachi MAF0132 Mass Air Flow Sensor

Hitachi MAF0132 Mass Air Flow Sensor

Hitachi MAF0132 is a mass air flow sensor built to measure the volume and characteristics of incoming air so the engine control system can calculate fuel delivery accurately. It is a direct-fit emission control sensor for the 2009 Audi Q7 and is calibrated for the listed application.

Key Features

• Measures intake air volume and airflow characteristics for engine management
• Precision sensing elements and quality components for consistent operation
• 100% air flow tested for application-specific performance
• Calibrated for the 2009 Audi Q7
• Protected circuitry and contaminant bypass port design, where applicable
• OE-approved design focus for emission control service

Application Details

Compatible With 2009 Audi Q7, N/A. This Hitachi MAF0132 sensor is also cross-referenced to Spectra Premium MA126 for the same application. Use MAF0132 when replacing a faulty Audi Q7 mass air flow sensor that is affecting air metering and engine control.

What It Helps Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or poor throttle response from incorrect air measurement
• Check engine lights related to mass air flow sensor performance
• Fuel trim issues caused by unmetered or misread intake air
• Emission test failures tied to airflow sensor errors

Installation Notes

Verify the connector style, housing shape, and engine application before installation. Inspect the intake tract for dirt, oil contamination, or air leaks that can affect sensor readings. After installation, clear diagnostic trouble codes and confirm proper airflow data with a scan tool.

Quality Assurance

Hitachi builds this sensor with precision elements and durable circuitry, then air-flow tests each unit for the listed application. The MAF0132 is calibrated for the 2009 Audi Q7 to support accurate engine management and emissions compliance.
