2Pcs Upstream & Downstream O2 Oxygen Sensor For 03-06 Toyota Camry RAV4 2.4L L4

O2 Oxygen Sensor Set for Toyota

This pair of upstream and downstream O2 oxygen sensors monitors exhaust oxygen levels and sends voltage signals to the ECU to adjust air-fuel mixture on 2003-2006 Toyota Camry and RAV4 models with 2.4L L4 engine.

Overview

The O2 oxygen sensor set replaces worn or failed primary and secondary sensors, restoring correct fuel trim and emissions performance. Designed for 2003-2006 Toyota Camry and RAV4 2.4L applications, these O2 oxygen sensors help the engine control module maintain the ideal air-fuel ratio, preventing rich or lean conditions. This plug-and-play O2 oxygen sensor pair is essential for resolving check engine lights and passing emission tests.

Built For Performance

• Heated zirconia sensing element reaches operating temperature quickly for accurate readings
• Direct-fit OE-style connector eliminates cutting or splicing
• Pre-coated threads with anti-seize compound for easy installation
• Dual-layer protection tube resists contamination and thermal shock
• Laser-welded stainless steel body prevents exhaust leaks
• Wide-band response ensures stable voltage output across engine loads

Fits These Machines

• for Toyota Camry (2003-2006) 2.4L L4
• for Toyota RAV4 (2003-2006) 2.4L L4

On-The-Job Use

• Replacing slow-responding sensors that cause P0133, P0153, or P0420 codes
• Restoring fuel economy after upstream sensor degradation
• Ensuring proper catalyst monitoring by downstream sensor
• Completing a full sensor refresh during exhaust or engine work

Specs At A Glance

Good To Know

Q: Do I need any special tools to install these O2 sensors? A: A standard oxygen sensor socket and torque wrench are recommended to avoid damaging the sensor body and ensure a proper seal.

Q: Will these sensors work with a California-emissions vehicle? A: These O2 sensors fit the listed engine and year regardless of federal or California emissions, but always match sensor position (upstream/downstream) before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
