Compatible Applications

• Chevrolet: MAF sensor harness connector – Cruze, Malibu, Equinox, Silverado (Delphi sensor platforms)
• Honda: Air flow meter and MAP sensor harness connector – Accord, CR-V, Civic (Delphi-sourced sensor variants)
• General: Fuel injector harness connectors on 5-pin Delphi sensor platforms

Diagnosis – MAF Sensor Faults

• P0100–P0104 (MAF Circuit): Before replacing the MAF sensor, inspect the 1928405138 connector for corrosion, bent terminals, or damaged wire seals – a faulty connector is a common root cause
• Rough idle + black smoke: A corroded MAF connector causes the ECU to read a low airflow signal and over-fuels the engine – check connector resistance before replacing sensor
• Intermittent fault after rain: Inspect wire seal integrity – moisture ingress at Pin 3 or Pin 4 causes intermittent signal faults and P0101/P0113

FAQ

Q: Is 1928405138 a MAF connector or an injector connector?
A: 1928405138 is a Delphi 5-pin waterproof connector used for both MAF sensors and fuel injectors depending on the application. Confirm the pin count and housing profile match your vehicle's harness before ordering.

Q: What is the difference between a MAF and MAP sensor connector?
A: A MAF (Mass Air Flow) sensor measures air volume entering the engine; a MAP (Manifold Absolute Pressure) sensor measures intake manifold pressure. They use different connector types – confirm which sensor your vehicle uses before ordering a replacement connector.
