This part cross-references Bosch 18043 for the same application.
What This Sensor Helps Address
- Check engine light related to oxygen sensor performance
- Incorrect air-fuel ratio readings from a worn downstream sensor
- Reduced fuel economy caused by inaccurate exhaust feedback
- Slow sensor response after contamination or age-related wear
- Emissions test failures tied to faulty downstream monitoring
Installation Notes
Verify the connector style, wire count, thread diameter, and downstream position before installation. This sensor is a specific-fit replacement, so match the vehicle application exactly to the listed fitment. Confirm the original sensor location and routing on the exhaust system before final tightening.
