Product Information

Downstream oxygen sensors monitor exhaust gases exiting the catalytic converter. Unlike upstream sensors, downstream sensors are primarily used to monitor catalytic converter efficiency rather than directly adjusting fuel trim.

Oxygen Sensor
The oxygen sensor works with the engine control unit to monitor exhaust composition and emissions system performance. A failed downstream oxygen sensor can trigger a check engine light, although similar faults may also indicate catalytic converter issues.

Common failure symptoms:

  • Reduced fuel mileage
  • Failed emissions testing
  • Check engine light
  • Poor driveability

About Bosch

Bosch is a global leader in automotive components and engineering innovation. Founded in Germany in 1886, Bosch has been at the forefront of automotive technology for over a century. They pioneered mass-produced fuel injection systems in 1967 and introduced the first oxygen (lambda) sensors in 1976 — setting the standard for modern engine efficiency and emissions control.

Today, Bosch supplies a wide range of OE and aftermarket parts trusted by vehicle manufacturers and independent repair shops worldwide. From ignition systems and sensors to filters and electronics, Bosch products are designed with precision and built for performance, safety, and reliability.
