How To Bypass Co Sensor On Generator? [Essential To Learn]

Carbon monoxide(CO) poisoning has been a significant cause of death amongst generator users. Thankfully, generator manufacturers have included a CO detector in new model generators. But, how to bypass the CO sensor on generator can be a valid concern, especially when the CO sensor starts giving false alarms and turning off your generator continuously.

So, how to bypass the co-sensor on generator? To bypass a co sensor, you’d need a plier for cutting the wires that run to the sensors. When you cut the cables, join them back together. The CO sensor light will still be on, but your generator won’t be turned off.

Co-sensors are still a relatively new technology in power generation, but they are a significant invention that will help people be safe from carbon monoxide poisoning. The problem with the CO sensor technology, however, is that sometimes it can just turn off your generator even when it is in open space. That is when you’d need to bypass the sensor.

It is not advisable to bypass any safety feature put on any machine. Still, in cases where the CO sensor will keep switching off intermittently, it is essential to learn how to bypass that feature.

What Is A CO Sensor On A Generator?

Carbon monoxide sensors are a very new technology for generators. CO sensors are features put in the generator to detect the presence of carbon monoxide in the atmosphere. CO sensors were placed in the generator to protect users from carbon monoxide poisoning. Many generator users have experienced fatalities while using generators that release carbon monoxide.

What Is A CO Sensor On A Generator

CO sensors will warn the users of carbon monoxide in the atmosphere and sound an alarm or even automatically turn off the generator.

Carbon monoxide detectors are relatively cheap and easy to get on your generator. You can also buy a generator that comes with the feature in-built. Many CO sensors run with batteries and are easily detachable or bypassed.

Here Are Some Pros And Cons Of The CO Sensor:

  • They are cheap.
  • CO sensor, even though it is a new technology, it is available in a lot of stores and modern generators.
  • CO sensors will protect generator users against the harmful effect of carbon monoxide.
  • They provide an accurate reading of the amount of carbon monoxide in the air
  • CO sensors have a limited lifespan.
  • They need to be changed every six months to one year.
  • They give false alarms and can turn off the generator too often.
  • Some CO sensors cannot detect low levels of carbon monoxide and hence may not give alarms until it’s too late.

Why Do You Need To Bypass A CO Sensor On Generator?

Because the CO sensor alarms are still a technology that is just starting to be implemented, the technology isn’t fully functional and optimized yet. Many CO sensor users complain of frequent false alarms, which leads to their generators turning off.

It is not advisable to turn off the CO sensor of your generator because it is put there for your safety. However, when the sensor of your gen starts to give off false alarms and turn off the generator, then you might want to know How to bypass CO sensor on generator.

How To Bypass Co Sensor On Generator

To bypass a carbon monoxide sensor, you’d need a plier, which you’d use in cutting or removing the wires that connect to the sensor.

How To Bypass Co Sensor On Generator

Next, you locate the CO sensor on your generator. They are usually at the back of the power panel.

After locating the CO sensor, you then cut or remove the two black wires or, in some cases, yellow and black wires that go into the sensor. Could you remove them and then join them? If you can, then remove them and join them together.

When you are done, the sensor light will still be coming on, but your generator will no longer go off. You can reverse this if you no longer require it.

Is It Safe To Bypass Co Sensor On Generator?

No. It is not safe to bypass the co-sensor on your generator. The Co sensor in itself is a safety measure that was put in the generator to prevent carbon monoxide poisoning. You are not advised to disconnect or take off the sensor entirely from your generator.

However, in cases where there is no real threat of carbon monoxide poisoning, and your gen keeps going off because of the Co sensor, you can temporarily bypass it.


How to Bypass co-sensor on generators has proven to be a source of significant concern for generator users worldwide. Due to co-sensor technology being new, many generators suffer from false alarms.
