Replacement REPT960926 Heated Oxygen Sensor 4-Wire Flange-Mount OEM Replacement

The Replacement REPT960926 is a heated, 4-wire, flange-mount oxygen sensor designed as a direct-fit OEM-quality replacement for select Toyota and Lexus vehicles. This O2 sensor monitors exhaust gas composition and communicates with the vehicle's engine control unit (ECU) to help maintain the optimal air-to-fuel ratio, supporting efficient combustion, fuel economy, and proper emissions control.

Key Features:

• Heated Design: Built-in heater circuit brings the sensor to operating temperature quickly after startup, reducing warm-up time and minimizing the risk of erroneous signals to the ECU
• 4-Wire Construction: Includes dedicated heater circuit wires alongside signal and ground wires for precise, reliable oxygen level reporting
• Flange-Mount Style: Secures to the exhaust pipe via a bolt-on mounting flange, providing a secure and stable installation
• OEM-Quality Replacement: Engineered to meet or exceed original equipment specifications for a direct-fit installation without modification
• Durable Construction: Built to withstand high exhaust temperatures and harsh under-vehicle conditions

A failing oxygen sensor can trigger a check engine light, cause rough idle, reduce fuel efficiency, and lead to catalytic converter damage over time. Replacing a worn O2 sensor with the REPT960926 restores proper engine management function and helps maintain emissions compliance.
