Dasbecan O2 Oxygen Sensor Kit for 2005-2011 Toyota Camry & 2006-2008 RAV4 — Upstream + Downstream 4-Pin Pair, Stainless Steel

Dasbecan O2 Sensor Kit replaces the upstream 234-4622 and downstream 234-9049 oxygen sensors for select 2005–2011 Toyota Camry and 2006–2008 RAV4 models, restoring accurate exhaust oxygen readings and enabling the engine computer to adjust fuel delivery.

These two oxygen sensors come as a matched upstream and downstream pair engineered to match factory fit and function for 2.4L L4 (2362cc) Toyota engines. Constructed from stainless steel and high-temperature materials, the sensors detect unburned oxygen in exhaust gases and send voltage signals to the vehicle’s engine control module. That data helps the ECU fine-tune fuel trim, support smoother idling and reduce excess emissions compared with a failing sensor. The kit includes one upstream (234-4622) and one downstream (234-9049) sensor, both with 4-pin connectors for direct replacement installation.

How do these sensors affect everyday driving?

Oxygen sensors supply the engine computer with real-time information about exhaust composition, which helps maintain the correct air–fuel ratio. When sensors read accurately, the engine runs more consistently, and throttle response and idle quality are improved. Worn or faulty sensors can cause rough idling, reduced fuel economy, and trigger the check engine light.

• Restores correct air–fuel feedback to the ECU
• Helps stabilize idle and throttle response
• Reduces chance of drivability issues and diagnostic trouble codes

Are these sensors a direct fit for my Toyota Camry or RAV4?

Yes—this Dasbecan kit is designed to be a plug-and-play replacement for the specified model years and engine size. Both sensors use the factory 4-pin, 4-wire connector format and match original mounting and thread specifications to simplify installation. Always confirm part numbers and vehicle compatibility before ordering.

• Compatible with 2005–2011 Camry (Base, CE, LE, SE, XLE, Hybrid)
• Compatible with 2006–2008 RAV4 (Base, Limited, Sport)
• Fits 2.4L L4 2362cc engine applications

What are the build and performance features of these oxygen sensors?

Manufactured with stainless steel and heat-resistant internals, the sensors are intended for long-term exposure to high exhaust temperatures. They measure unburned oxygen and convert that information into electrical signals for the engine control module. This design supports steady operation over extended service life when installed correctly.

• Stainless-steel housing for corrosion resistance
• High-temperature materials for sensor element durability
• Stable voltage output to maintain consistent ECU feedback

How difficult is installation and what’s included in the package?

Installation is straightforward for a mechanically inclined person with basic tools; both sensors are direct replacements using the OEM-style 4-pin connectors. No cutting, splicing or additional adapters are required. The package contains one upstream sensor and one downstream sensor to replace both positions in one service.

• Plug-and-play 4-pin connectors—no modification required
• Includes upstream (234-4622) and downstream (234-9049) sensors
• Saves time vs. sourcing individual parts separately

Who this is for: This Dasbecan O2 sensor kit is for Toyota Camry and RAV4 owners or independent technicians who need a matched upstream and downstream replacement set for the 2.4L L4 engine. It suits drivers troubleshooting persistent check engine codes related to oxygen sensors, those experiencing rough idle or decreased fuel economy, and anyone wanting a cost-effective, factory-style replacement that installs with existing connectors.
