Honda 5-Pin HV/HVG 040 Series Air Flow Meter (MAF) Waterproof Connector – OEM 6189-6909
Direct OEM-specification replacement for the Sumitomo HV/HVG 040 series 5-pin waterproof wire harness connector used on mass air flow (MAF) sensors and air flow meters across Honda platforms. Cross-references Sumitomo / Honda OEM part number 6189-6909. Uses the 040 contact series in black nylon housing with waterproof sealing — the HVG 040 series is Sumitomo’s standard connector for MAF sensors and air flow meters on Honda’s K-series, R-series, and J-series engine platforms.
The 5-pin MAF sensor connector is located on the air intake pipe, between the air filter and the throttle body. It is exposed to heat from the engine bay and vibration from the intake system. A failed connector causes the ECM to lose mass air flow data, triggering P0100–P0104 (MAF sensor circuit) fault codes. Without MAF data, the ECM cannot accurately calculate the air mass for fuel injection, causing the engine to run rich or lean, increasing fuel consumption and emissions, and potentially causing catalytic converter damage.

Q: My Honda has a P0102 MAF sensor low voltage fault — could it be the connector?
A: Yes. A corroded or open 5-pin MAF connector is a common cause of P0100–P0104 on Honda vehicles. Test the MAF sensor output voltage at idle (typically 1.0–1.5V) — if the sensor is within specification, the fault is in the connector (OEM 6189-6909) or wiring.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
