Toyota 2-Pin Waterproof Sensor Connector – OEM 90980-12490 | Female

The OEM 90980-12490 is a 2-pin waterproof female connector used in Toyota sensor harnesses including wheel speed sensors, temperature sensors, and other 2-wire sensor circuits. Sealed nylon housing with IP67-equivalent waterproofing ensures reliable sensor signal continuity in underhood and underbody environments. Available bare or with 15cm pre-wired leads.

Key Specifications

Why Sensor Connectors Fail

Toyota sensor connectors in underhood and underbody environments are exposed to heat, vibration, road spray, and salt. Terminal corrosion or housing damage causes intermittent sensor signal faults, triggering ABS codes (C-codes), temperature sensor faults (P0115–P0118), or other 2-wire sensor circuit errors. Replacing the connector restores clean sensor signal continuity.

Variant Guide

• Female – Bare 2-pin housing with terminals
• Female 15CM – Pre-wired with 15cm leads for direct splice-in installation

Installation Steps

1. Disconnect the vehicle battery
2. Locate the 2-pin sensor connector on the affected sensor harness
3. Release the locking tab and unplug the original connector
4. Transfer terminals to the new housing or splice in the pre-wired variant
5. Reconnect and clear sensor fault codes with Toyota Techstream
