Removal & Installation
- Oxygen sensors (4) are mounted in exhaust pipe before and after catalytic converters. Sensor is equipped with a permanent pigtail, which must be protected from damage when sensor is removed.
- Ensure sensor is free of contaminants. Avoid using cleaning solvents of any type. Sensor may be difficult to remove if engine temperature is less than 120°F (48°C). If re-using sensor, always use anti-seize compound on threads before installation. Tighten sensor to specification. See TORQUE SPECIFICATIONS .
