Mazda / Toyota 2-Pin Female Ignition Coil / CVVT / Fuel Injector Connector – OEM GS1D-67UC1 / MG640605 / 90980-10609

Direct OEM-specification replacement for the 2-pin female wire harness connector used on ignition coils, CVVT (Continuously Variable Valve Timing) solenoids, and fuel injectors across Mazda and Toyota platforms. Cross-references OEM part numbers GS1D-67UC1 (Mazda), MG640605, and 90980-10609 (Toyota). Black nylon housing — a versatile 2-pin connector used across multiple engine management actuator circuits on Mazda’s SkyActiv and MZR engine platforms and Toyota’s VVT-i engine platforms.

What Problem Does This Connector Solve?

The 2-pin connector is used on three critical engine management actuator circuits. As an ignition coil connector, a failed connection causes a cylinder misfire (P0300–P0304). As a CVVT solenoid connector, a failed connection causes the variable valve timing system to default to a fixed cam position, triggering P0010–P0015 (VVT system) fault codes and causing reduced performance and fuel economy. As a fuel injector connector, a failed connection causes a cylinder to run lean, triggering a misfire fault.

Frequently Asked Questions

Q: My Mazda CX-5 has a P0011 CVVT fault — could it be the solenoid connector?
A: Yes. A corroded or open 2-pin CVVT solenoid connector is a common cause of P0010–P0015 VVT faults on Mazda SkyActiv engines. Inspect the connector (OEM GS1D-67UC1) before replacing the CVVT solenoid valve.

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