Hello to everyone. I have a problem with the o2 sensor after removing the catalyst.How do I deceive an o2 sensor?

 

You'll need to get what's called an "o2 emulator" or "o2 eliminator" or "o2 simulator".

Basically it's a device with a small circuit board that emulates a working o2 sensor, in place of a real o2 sensor.

Depending on where you live, it might not be legal for emissions.

Good luck.

 

What year of truck and what engine?

Hi friends. I have ford f 150, 2001, engine 4.6I want to share my experience.Removed the catalyst and thought for a long time how to deceive sensor2 О2.Found a solution.4 wires depart from sensor О2. 2 wires - sensor heating. 2 wires - sensor data.I cut off 2 wires (sensor data) and connected them to each other.The other 2 wires (sensor heating) were left in place.The sensor has not been removed.

 

Sorry. Here's the right photo.

 

The first real repair in 19 years. + changed all oils and liquids.
