2-Pin Fuel Injector Connector – Type A & Type B Female OEM

This 2-pin female connector is used in fuel injector harnesses across multiple automotive brands. Available in Type A and Type B housing configurations to match different OEM injector connector designs, bare or with 15cm pre-wired leads. The fuel injector connector is a critical engine management circuit component – a degraded connector causes injector misfires, P0200-series fault codes, and rough idle.

Key Specifications

Fuel Injector Connector Pin Functions

A 2-pin fuel injector connector serves the injector solenoid: one pin carries the injector power supply (+12V or switched), and the other carries the ECU-controlled ground signal that triggers the injector pulse. A corroded or damaged connector on either pin causes injector misfires, lean/rich cylinder conditions, and P0201–P0208 (individual cylinder injector circuit) fault codes.

Why Injector Connectors Fail

Fuel injector connectors are mounted directly on the injector body, exposed to extreme underhood heat, fuel spray, and vibration from the engine. Terminal corrosion, housing melting from heat soak, or connector body cracking causes intermittent injector faults. Symptoms include rough idle, misfires, P0300-series misfire codes, and P0201–P0208 injector circuit faults.

Variant Guide

• Type A Female / A Female 15CM – Type A housing for specific injector connector design
• Type B Female / B Female 15CM – Type B housing for alternate injector connector design

Compare the housing shape and locking tab of your existing OEM injector connector to select Type A or B.

Installation Steps

1. Depressurize the fuel system before working on injector components
2. Allow the engine to cool before working near injectors
3. Locate the 2-pin injector connector on the affected cylinder’s injector
4. Release the locking tab and unplug the original connector
5. Transfer the terminal to the new housing or splice in the pre-wired variant
6. Reconnect and clear P0200-series fault codes with a scan tool

Frequently Asked Questions

Q: What fault codes indicate a failed injector connector?
A: Common codes include P0201–P0208 (individual cylinder injector circuit open/short), P0300–P0308 (cylinder misfire detected), and lean/rich fuel trim codes (P0171/P0172) caused by injector misfires.

Q: How do I identify Type A vs Type B?
A: Compare the housing body shape, locking tab position, and connector orientation of your existing OEM injector connector with the product images for each type.

Q: Is this compatible with both port and direct injection?
A: Yes. This 2-pin connector is used in both port fuel injection (PFI) and gasoline direct injection (GDI) systems. Verify the housing type matches your injector connector.

Q: Are terminals included?
A: Yes, terminals are included with all variants.
