Bosch 13354 Oxygen Sensor

Bosch Oxygen Sensor for Lexus and Toyota

Bosch 13354 is a specific-fit, narrow-band heated oxygen sensor built for downstream and upstream applications across select Lexus and Toyota vehicles. It uses a threaded metal housing, 4-wire blade connection, and integrated wiring harness to deliver stable air-fuel feedback to the ECU for accurate closed-loop control.

As part of the Bosch Engineered Oxygen Sensor line, this sensor reflects Bosch’s OE development history in oxygen sensing, including faster light-off response, improved lambda accuracy, and reliable operation under heat and vibration. It is a standard replacement choice for drivers servicing Lexus IS, RC, GS, and Toyota Tundra, Tacoma, Prius, Camry, and related applications.

Detailed Description

Bosch 13354 is engineered to measure oxygen content in the exhaust stream and send accurate air-fuel-ratio data to the ECU. That feedback helps maintain stable combustion control, supports emissions management, and keeps the engine operating in closed-loop mode as intended. The narrow-band heated design promotes quicker sensor activity after startup, while Bosch ceramic sensing elements and optimized heater control support consistent signal output across changing temperatures.

This Bosch Engineered Oxygen Sensor line is backed by more than five decades of OE development and is built for the demands of modern and older Toyota and Lexus platforms. It is a direct-fit replacement for applications such as Lexus IS500, RC F, GS F, IS300, GS350, IS250, and Toyota Tundra, Tacoma, Sequoia, Venza, Prius, Camry, Solara, Echo, Matrix, and more. This part cross-references Toyota/Lexus OE numbers such as 894650C300 and 894650T040 for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Rich or lean fuel trim readings caused by a failing sensor
• Slow closed-loop response after startup
• Unstable idle or drivability issues tied to inaccurate exhaust feedback
• Emissions test failures caused by degraded sensor output

Installation Notes and Tips

• Confirm the exact year, make, model, and sensor position before ordering; this part is application-specific.
• Verify whether your vehicle uses upstream or downstream placement, including right or left side where listed.
• Inspect the connector shape, wire count, and thread size before installation.
• Use proper oxygen sensor service tools to avoid damaging the threaded bung or sensor body.
• Check for exhaust leaks or wiring damage that could affect sensor readings after replacement.

Quality Assurance

Bosch supplies this oxygen sensor as an OE-proven replacement built to the same engineering standards that support vehicle manufacturer applications. The design emphasizes accurate signal response, durable materials, and dependable performance in high-heat exhaust environments.
