Honda K-Series Black 2-Pin Sensor Connector – IAT / VTC / OBD2 (K20 / K24 / D17)

OEM-Style Black 2-Pin Connector for K-Series & OBD2 Honda Applications

The Honda Black 2-Pin Sensor Connector is an OEM-style plug used across K-Series engines and various late-model OBD2 Honda platforms. This connector is commonly found on IAT (Intake Air Temperature), VTC oil control solenoid circuits, and other 2-pin engine management sensors.

Due to Honda’s connector standardization, this plug is also used on select OBD2 B-Series, D-Series, and D17 applications, making it a versatile replacement or harness-build connector.

Designed for professional harness repair and motorsport wiring fabrication, this connector provides secure terminal retention, proper sealing, and reliable sensor signal integrity.

Common Applications

This black 2-pin connector is frequently used on:

• K20 engines

• K24 engines

• D17 engines

• Late-model OBD2 B-Series

• Late-model OBD2 D-Series

Common sensor uses include:

• IAT (Intake Air Temperature) sensor

• VTC oil control solenoid

• Various 2-pin Honda engine sensors

• Select solenoid and sensor circuits on newer Honda platforms

If your engine uses a black 2-pin rectangular Honda sensor plug, this is the correct OEM-style replacement or harness fabrication solution.
