J.C. Whitney JRT96090005 Heated 4-Wire OEM Replacement Oxygen Sensor

The J.C. Whitney JRT96090005 is a direct-fit, OEM replacement heated oxygen sensor designed for the 2004–2005 Toyota RAV4 equipped with the 2.4L I4 (2AZ-FE) engine. This sensor restores proper exhaust monitoring and fuel management function, helping eliminate check engine lights caused by a failed or degraded O2 sensor.

The oxygen sensor monitors unburned oxygen levels in the exhaust stream and transmits a voltage signal to the engine control unit (ECU). The ECU uses this data to continuously adjust the air/fuel mixture, optimizing combustion efficiency, reducing harmful emissions, and maintaining fuel economy.

Key Features:

• Heated sensor design — integrated heater element brings the sensor up to operating temperature quickly, ensuring accurate readings even during cold starts
• 4-wire configuration — two heater circuit wires and two signal wires for precise, reliable communication with the ECU
• Direct-fit replacement — designed to match OEM mounting specifications with a threaded installation; no cutting or splicing required
• Female connector — mates directly with the factory wiring harness connector
• Wire harness length: 25.98 inches
• Mounting style: Threaded-in, 7/8 in. (22 mm) hex size
• OEM cross-references: 250-24838, 234-4503
• Sold individually

Replacing a faulty oxygen sensor (O2 sensor) can resolve symptoms such as poor fuel economy, rough idle, failed emissions tests, and illuminated check engine lights with codes such as P0136, P0137, or P0138. This sensor is a cost-effective, quality alternative to dealer-sourced OEM parts.
