Removing Oxygen Sensor Upstream Of Catalytic Converter
WARNING: This page is about a different variant/trim than selected.
CAUTION:
Hot components
- Risk of burns
- → Let hot components cool down.
- → Wear personal protective gear.
CAUTION:
Risk of damage to sensor if handled incorrectly!
- → Do not remove the plastic cap on the thread until just prior to fitting the sensor. The grease used on the thread must never get into the connector.
- → Protect sensors - before and after fitting - against mechanical shocks.
- → Sensors that were dropped on the floor must not be used owing to the risk of a broken ceramic insulator.
- → The cables must not be twisted or kinked when the sensors are screwed in. Avoid pulling on the cable and connector.
- → Cleanliness in the housing of the plug connections is of utmost importance for the oxygen sensor to function
- → properly. Particles of dirt can impair the function of the sensor. The connector must therefore be protected against any and all types of soiling.
- → Sensors with a soiled or damaged connector must no longer be used.
- → Protect the cables and connectors when carrying or moving the exhaust system with the sensors already fitted.
- → High-pressure cleaning equipment must not be used in the area of the sensors and plug connections.
- → Contact and corrosion agents, e.g. Stabilant, must not be applied to the plug contacts of the oxygen sensors.
Information
- Pre-treat corroded components with anti-rust agent or heat.
Information
The > 3337 - ring wrench set for oxygen sensor is the ideal tool.
