• Emissions test failures related to sensor performance
• Slow sensor response from a worn heated oxygen sensor

Installation Notes and Tips

Verify the exact position on your vehicle before ordering, since this part is listed for front, front left, front right, and rear locations depending on application. Match the 4-wire connector, round plug style, and 18 x 1.5 mm thread size to the original sensor before installation. Use the included instruction sheet and confirm proper routing of the 480.0-length lead away from hot exhaust components.
