FAQs

Does this sensor include the air intake housing?

No, this product is an insert-style sensor and does not include the outer plastic housing.

It is designed for specific models requiring part number AF10374-12B1 or AF10757-12B1. Please verify compatibility with your vehicle's specific engine requirements.

Can I touch the wire element during installation?

No, you should never touch the delicate sensing element as skin oils can damage the sensor's accuracy.

What is the operating voltage?

This sensor operates on a standard 12V electrical system.

Should I reset the ECU after installation?

It is highly recommended to reset the computer or clear the stored codes to ensure the engine adjusts to the new data inputs correctly.

Troubleshooting

Check engine light remains on after installation

Clear the diagnostic trouble codes (DTCs) using an OBD-II scanner to allow the ECU to relearn the new sensor values.

Setup, Compatibility & Care

To install the Delphi AF10374-12B1, locate your vehicle's air intake assembly between the air filter box and the intake manifold. Carefully unscrew the mounting screws of the old sensor insert and remove the unit. Before installing the new Delphi sensor, clean the housing cavity using an approved MAF sensor cleaner. Once dry, insert the new sensor, ensuring the O-ring is properly seated to prevent unmetered air leaks. This part is compatible with select Ford and Mazda models requiring a 4-pin configuration. Avoid touching the internal sensing elements with your fingers, as oils from your skin can contaminate the calibration.
