Removal & Installation

Disconnect electrical connector and remove oxygen sensor. Install new oxygen sensor and ensure clearance is maintained at boot. When installing new sensor, do not remove coating from threads or install with any type of sealant. Reconnect electrical harness connector. See Fig 1.

NOTE: DO NOT attempt to reinstall an oxygen sensor. Reinstallation of a sensor without the special glass bead thread coating may require replacement of exhaust system.
