How to Bypass CO Sensor on Champion Generator with Safety Precautions?

CO sensors in generators alert people to the danger before they are exposed to harmful levels of Carbon Monoxide. So it is necessary to know the co sensor bypassing process.

So, how to bypass Co Sensor on champion generator? 

The process is you first have to shut down your champion generator and access the co sensor wire when the generator is at room temperature. Then, remove the control panel’s screws, and there will be a white little box; disconnect it. If your generator operates accurately afterward, then you bypassed it successfully.

It’s recommended that this entire process is conducted by a professional or at least under expert supervision. To gather more knowledge about the process go through this article.

Warning And Precautions to Maintain Before Bypassing the CO Sensor

In order to prevent the formation of Carbon Monoxide, it is crucial to maintain all precautions before bypassing the CO sensor. You need to have knowledge about low-oil Co Sensor too because it can also cause unpleasant situations. 

However, We need to use generators in well-ventilated spaces and perform routine maintenance. That is why you need to maintain some unavoidable safeguards. We highlighted some for you. These include-

  • Always remember to place the generator in a space with good ventilation and never put a fuel container, gasoline tank, LPG cylinder, or any other flammable object in the engine’s exhaust stream.
  • Wait until the generator reaches room temperature.
  • To enable the appropriate performance cooling, maintenance, and repair, a minimum of 3 feet (91.4 cm) of airflow space must be allowed on all sides of the generator.
  • Never try to start a faulty or damaged generator. Make sure that the cap of the fuel, spark plug, air filter, lines of fuel, and exhaust system are all installed correctly.
  • Be sure to read the owner’s handbook or user guide before beginning the procedure.
  • Always turn off all types of equipment that are gas-powered in the area before beginning the process.
  • Always remember to wear personal protective equipment (PPE), including a mask, gloves, and safety goggles.

How To Bypass CO Sensor On Champion Generator

These steps will help you to bypass the Co sensor in your Champion generator easily.

Step 1: Finding Champion Generator CO-Sensor Location:

According to the particular type and construction of the generator, the placement of the carbon monoxide (CO) sensor may differ. Generally, the CO sensor is often located close to the generator’s exhaust.
The CO sensor may be included in the generator control panel on some Champion generator types. But sometimes on other models, it may be a separate sensor located close to the exhaust. 
However, the CO sensor has to be appropriately labeled for quick identification in both scenarios. You should consult the user manual or get in touch with the manufacturer directly for further instructions on how to find the CO sensor on your Champion generator.

Step 2: Cool Down to Room Temperature

At first, You should shut off the generator. After that, wait until the generator’s engine and other components are at normal temperature. This is because metal components could expand as a result of the generator’s heat. It also makes them more difficult to work with, and there may also be residual heat that can cause burns or other injuries if touched.

Step 3:Find and Disconnect the Sensor

At this step, you have to locate the co sensor correctly and after getting it you have to bypass the sensor. Most often, the CO sensor is located in the control panel. To access the CO sensor’s wires, remove the control panel’s screws. Finally, You can able to see a white little box; try to disconnect it in a safe hand

Step 4: Restarting the Generator

After a while, turn on the generator. If your generator operates flawlessly, you have effectively bypassed it. It is necessary to restart your generator after the work is done. Unless you won’t understand whether it is working perfectly or not.

Step 5: Replace the Faulty Sensor

If the current CO sensor is broken, get a new one and swap it out. Because using a faulty generator may cause the deadliest incidents.

Is It Okay to Have A Co Sensor on A Generator?

Carbon monoxide detectors can be very helpful by accurately measuring the amount of gas in the air to make sure a hazardous concentration is not reached. Best generators in the market do have Co senor for safety reasons. Some pros and cons are mentioned below.

People can avoid the dangerous effects of carbon monoxide by using carbon monoxide detectors.CO sensors occasionally set off false alerts, particularly if the generator is being utilized in an area with limited ventilation or if it is not being properly maintained.
The cost of carbon monoxide detectors is not very high.A generator’s price may increase if CO sensors are not a standard feature, in particular.
The ability to buy a carbon monoxide detector offline or online is simple and convenient.If the generator is located in a large area or outdoors, the sensor may not be effective in detecting the gas.
You may feel secure knowing that you and your family are safe from the risks of CO gas by installing a CO sensor on your generator.The lifetime of a carbon monoxide detector is only 5-7 years.

Alternative Processes of Bypass CO Sensor Method?

It is not recommended to ignore or bypass a CO sensor. It is advised to fix the problem or replace the sensor if you are having CO sensor problems rather than ignoring them. Some other alternatives are mentioned for you. 

Try to Use A Battery-Powered Portable Power Station: 

For temporary power requirements, a portable power station with batteries is a reasonable substitute for a generator. They don’t emit any pollutants or carbon monoxide and are safe to use indoors.

Using A Solar-Powered Generator: 

Currently, a solar-powered generator is an efficient alternative to a regular generator. We can use it indoors because it doesn’t produce any carbon emissions. They don’t cause noise pollution and are ecologically beneficial. 

Using A Generator Fueled by Propane And Natural Gas:

Generators fueled by propane and natural gas are safer than generators powered by gasoline. They don’t need gasoline, which may be dangerous to store and use, and produces fewer pollutants.

Utilize Your Power Inverter:

Electricity inverters are devices that convert DC electricity from a car battery or another source into alternating current (AC) for small electrical equipment.  This is a practical solution for powering tiny appliances or charging mobile devices.

Remember, when using any type of generator or power source, it is important to follow all manufacturer instructions. It is also necessary for you to have an idea about bypassing the Co censor in another generator model.


Now you know How to Bypass Co Sensor on The Champion Generator? It’s crucial to remember that the sensor is there for a particular reason and removing it would result in losing an essential safety feature. Always remember that prevention is always preferable to treatment, thus it’s crucial to adopt the appropriate safety measures to reduce your chance of exposure to CO gas.

Frequently Asked Questions (FAQs):

How long will a Champion generator last?
