Laser Tools Particulate Sensor Thread Chaser - M22 x 1.5

This specific M22 x 1.5 thread chaser is primarily intended for use on particulate sensors found in BMW, MAN, and VW Group vehicles. Always confirm the thread size before use.

Axle grease lubricates the threads during cleaning and, more importantly, traps any metal filings or carbon debris removed by the chaser. This prevents contamination of the sensor port and exhaust system.

It is recommended to use this thread chaser whenever a particulate sensor is removed and reinstalled, especially if the threads appear dirty, corroded, or if experiencing sensor-related diagnostic trouble codes.

The TiN coating enhances the hardness and durability of the tool, providing better wear resistance and a longer service life compared to uncoated tools.

No, this chaser is specifically designed for M22 x 1.5 threads. Laser Tools offers other part numbers for different thread sizes (e.g., M12, M14, M16, M18, M20).

Fouled or damaged sensor threads can lead to improper sealing, exhaust leaks, inaccurate sensor readings, and potentially trigger diagnostic trouble codes (DTCs), resulting in poor engine performance or failed emissions tests.

Ensure you are using the correct M22 x 1.5 size. Apply more grease and try rotating gently. If still binding, there may be cross-threading or damage to the original threads which may require professional repair beyond the scope of the chaser.

Ensure sufficient axle grease is applied to the flutes. Clean any packed debris from the flutes and reapply grease. Ensure the chaser is rotating correctly and not just scraping.

Inspect the TiN coating and cutting edges. If significantly worn or damaged, performance may be compromised, and the tool should be replaced to avoid damaging the vehicle's threads.
