Full details

The Neilsen Lambda Sensor Remover & Installer is a professional-grade 22mm socket designed for automotive technicians and DIY enthusiasts who need to service oxygen sensors in tight engine or exhaust bays. Its 200mm extended length provides the reach required for deep-seated sensors, though its specialized design is strictly intended for 22mm applications and may not fit sensors with unique harness configurations.

FAQs

Will this tool work on all lambda sensors?

It is designed for standard 22mm sensors. Please verify your specific sensor size before use.

Can I use a power impact gun with this tool?

The tool is compatible with air hammers, but high-torque impact guns may cause damage to the sensor or the tool itself.

What is the drive size?

The tool features a standard 3/8-inch square drive.

How long is the tool?

The tool measures 200mm in length.

Is this tool suitable for home mechanics?

Yes, it is suitable for both professional mechanics and automotive enthusiasts.

Troubleshooting

Socket will not seat onto the sensor hex

Clean debris, rust, or excess heat-shield material from the sensor base using a wire brush.

Tool slips during use

Ensure the socket is pushed fully down onto the hex head; if the sensor is rounded, consider using penetrating oil first.

Difficulty getting the wire harness through the slot

Verify the electrical connector is disconnected from the main vehicle harness, allowing the wire to hang free.

Pros and Cons

Pros

Extended 200mm length for excellent access in restricted areas
Compatible with both manual ratchets and pneumatic air hammers
Protects sensor hex head from rounding off during removal
Essential for exhaust system and catalytic converter maintenance

Cons

Limited to 22mm sensor sizes only
May require extra clearance for very wide sensor electrical harnesses
Requires proper socket alignment to avoid damage on brittle sensors

Setup, Compatibility & Care

To use the tool, ensure the engine is cool to prevent burns and to minimize the risk of stripping threads in the exhaust manifold. Slide the wiring harness through the side gap of the tool before seating the socket onto the sensor. After use, wipe the tool clean with a shop rag to remove road grime or exhaust residue. Store in a dry toolbox to prevent rust. Do not use the tool for non-22mm fasteners, as this may compromise the structural integrity of the socket walls.
