Learn how to bypass low oil sensor on generator with this 8-step guide. Keep your power supply running smoothly with these helpful tips and tricks.
While low oil sensors are designed to protect the generator from damage due to insufficient lubrication.
If the generator keeps on running on low oil, internal friction can permanently damage the internal components.
While low oil sensor is an incredible safety feature, they can also be a nuisance if they are triggered unnecessarily.
Fortunately, there are ways to bypass the low oil sensor and keep your generator running smoothly.
In this article, I’ll share some tips and tricks for bypassing the low oil sensor on your generator.
I have explained one general method, one for my champion generator, and one for my Generac generator.
So let’s dive in and learn how to bypass that pesky low oil sensor!
The tools required to bypass the low oil sensor on a generator may vary depending on the make and model of the generator, but some common tools that may be needed include:
How to Bypass Low Oil Sensor on Generator in 8 Steps?
Before attempting to bypass the low oil sensor on your generator, it’s important to understand that doing so may void your warranty and could potentially cause damage to your generator if you’re not careful.
However, if you’re experiencing issues with a faulty low oil sensor or simply want to bypass it for some other reason, here are some general steps I want you to follow:
Step 1: Locate the Low Oil Sensor on Your Generator
This will typically be a small device located near the oil reservoir. It may be labeled as a “low oil switch” or “oil level sensor.”
Read the user manual or manufacturer’s instructions for specific guidance on where to find the low oil sensor on your particular model of generator.
Step 2: Remove the Sensor
Using a screwdriver or wrench, remove the sensor from the generator. This step will vary depending on the type of sensor and the make and model of your generator.
Be sure to follow any instructions provided by the manufacturer to avoid damaging the sensor or other components of your generator.
Step: 3 Disconnect Electrical Connection
Once the sensor is removed, disconnect any electrical connections that are attached to it.
The low oil sensor will typically be connected to two wires, which should be disconnected before proceeding to the next step.
Step: 4 Take a Reading with a Multimeter
Use a multimeter to test the electrical continuity of the two wires that were attached to the sensor.
Set your multimeter to the “continuity” setting and touch the probes to the two wires that were attached to the low oil sensor.
You should get a reading of “closed” or “continuity” when the wires are connected, and “open” when they are disconnected.
Step 5: Connect Two Wires
Connect the two wires together using electrical tape or wire connectors.
Once you have determined which wires were connected to the low oil sensor, connect them together using electrical tape or wire connectors. This will create a closed circuit that bypasses the low oil sensor.
Step 6: Put Back the Sensor
Replace the sensor back into its original location and reattach any bolts or screws that were removed earlier.
Carefully replace the low oil sensor back into its original location on the generator and secure it in place using any bolts or screws that were removed earlier.
Step 7: Check the Oil level.
Before starting up your generator, be sure to check the oil level to ensure that it is at the appropriate level. If the oil level is too low, it can cause damage to your generator even if the low oil sensor has been bypassed.
Step 8: Start up your generator
Turn on your generator and run it for a few minutes to ensure that it is running smoothly and that the low oil sensor has been successfully bypassed.
If the generator runs without shutting off due to low oil, then you have successfully bypassed the low oil sensor.
How to Bypass Low Oil Sensor on a Champion Generator?
- Low-oil sensors on most Champion generators are located near the oil cap and dipstick. Just near the fill cap.
- It will be either two red wires or two yellow wires.
- Disconnect both wires.
- Start the generator.
- Let it start for a minute or so.
- Now connect both wires.
- Turn OFF the generator and let it rest for a minute or so.
- Now start the generator with both wires connected to each other.
- If the generator starts normally, the troubleshooting is successful.
- If it doesn’t, just bypass the low oil sensor by disconnecting the wires.
NOTE: If you know how to replace that little green sensor, replace it. If you don’t know, hire a mechanic to prevent further damage.

How to Bypass Low Oil Sensor on a Honda Generator?
- Low-oil sensors on Honda generators are located between the switch and the coil.
- With the help of a male/female switch, two blacks are connected together.
- Disconnect the wires as we did with the Champion generator.
- Start the generator and let it run for a few minutes.
- Now connect both wires.
- Now start the engine with the wires connected.
- If the generator starts, troubleshooting is successful.
What are the Effects of Low-Oil Sensor Malfunctioning?
The engine of a generator is designed to operate with a certain amount of lubrication provided by the oil. If the oil level drops below this point, the engine can suffer damage due to increased friction and heat.
Without the protection provided by the low-oil sensor, the engine can suffer serious damage that may require costly repairs or replacement.
When the oil level is too low, the engine can overheat due to increased friction and heat. This can cause the generator to shut down, which can be frustrating if you’re relying on it for power.
A generator that is running with low oil may experience reduced efficiency, which can cause it to consume more fuel than it would if it were running with the appropriate level of oil. This can lead to increased fuel costs over time.
Increased Maintenance Costs:
A low-oil sensor malfunction can lead to increased maintenance costs due to the increased wear and tear on the engine.
Regular oil changes and engine maintenance can help mitigate these costs, but a malfunctioning low-oil sensor can make it more difficult to keep your generator in good working order.

Frequently Asked Questions (FAQs)
Is it safe to bypass the low oil sensor on a generator?
Bypassing the low oil sensor on a generator can create safety risks, as it eliminates an important safety feature that is designed to protect the engine and prevent fires or other hazards. In addition, if the engine suffers damage due to low oil, it can create additional safety risks such as overheating, smoke, or even fires.
Can I bypass the low oil sensor on my generator?
It is possible to bypass the low oil sensor on a generator, but it is not recommended. Bypassing the sensor can lead to engine damage, safety hazards, warranty issues, and environmental impact. It is important to weigh these risks and consider alternative solutions, such as adding more oil or repairing or replacing the sensor, before deciding to bypass the low-oil sensor.
What are the risks of bypassing the low oil sensor on my generator?
The risks of bypassing the low oil sensor on a generator include engine damage, safety hazards, warranty issues, and environmental impact. Running a generator with low oil can lead to increased friction, heat, and engine damage, which can be costly to repair or replace. In addition, bypassing the sensor can create safety hazards and void the manufacturer’s warranty.
How can I tell if the low oil sensor on my generator is malfunctioning?
A malfunctioning low oil sensor on a generator may trigger a false alarm, indicating that the oil level is low even when it is not. In some cases, the generator may shut down or fail to start if the sensor is malfunctioning. It is important to regularly check the oil level on your generator and have it serviced if you suspect a problem with the low oil sensor.
What should I do if the low oil sensor on my generator is malfunctioning?
If the low oil sensor on your generator is malfunctioning, it is important to have it repaired or replaced as soon as possible. Ignoring a malfunctioning sensor can lead to engine damage and safety hazards. Contact a qualified generator technician to diagnose and repair the problem.
