The OSF-104 Oxygen Sensor Fix is designed to permanently clear the Check Engine light caused by faulty O2 sensor readings. It is universal and designed to work on any zirconia sensor with one, two, three or four output.
A faulty O2 sensor reading can be caused by several things such as:
- Worn out catalytic converter
- Fuel contamination
- Aftermarket modifications
This product does NOT meet USA emissions regulations. It is the end users’ responsibility to comply with local laws and regulations. Compatible with Toyota and Lexus vehicles. Does NOT replace primary O2 sensor.
