How To Bypass Low Oil Sensor On Generator

Simply detach the wire from the low oil pressure switch and tape it so it does not hit the ground to bypass the switch. The switch disables the ignition by allowing the ground to pass through it. It won’t be able to disable the ignition if it can’t ground out. Thank you, that was easy.

How to get around the generator’s low oil sensor: a step-by-step guide:

If you’re having issues like the ones described in this article with a generator that won’t start because the oil sensor reads “poor” oil when the tank is full, you might look for a temporary solution.

Instead of measuring the oil in the tank, the sensor can become stuck at the bottom of the tank, directly touching the surface. You can briefly disconnect your sensor and start the engine if this happens. We’ve included a step-by-step guide to that will show you how to do it safely:

First, make sure you read the safety instructions above and follow them properly. You should then identify the low oil pressure switch. Here you should find a cable. The cable can be easily removed from the switch. Tape the wire so that it does not touch the ground.

The switch cannot be activated to disable the ignition with this wire removed. The generator would be able to start without being stopped by the low oil sensor switch. When the generator is turned on, the oil temperature rises and the viscosity changes, allowing the previously stuck sensor at the bottom of the crankcase to loosen.

When you’re certain the sensor is no longer stuck, reattach the wire to the switch for future use. Alternatively, you can look on the website or in the store where you bought your generator and see if they sell replacement equipment. It is vital that you get the problem fixed or else you risk damaging the generator and anything that is running on it.

Before We Again:

Until we show you how to disable your generator’s low oil sensor, it’s important to note that this can only be done if the sensor is being activated excessively. It’s inevitable that machinery will break down at some stage, and a faulty low oil sensor is one of them. This should not be used to keep your generator running all the time.

They might also be able to give you advice on the problem or recommend that the generator be returned. Always read and obey any instructions in the owner’s manual first. However, we recognize that there will be occasions when it is necessary to act quickly.

If any component of your generator appears to be faulty, we recommend contacting the manufacturer directly before following our advice. This is to make sure the producer is informed.

And if there is fuel in the tank, why does an oil sensor shut off?

Many generators have a low oil sensor and automatic shutdown, which is a significant feature. It shuts down the machine if the fuel level drops too low, preventing the generator from overworking itself and causing serious harm to the generator and everything else connected to it.

A faulty switch, for example, can continue to show that there is no oil when you know you have just refueled. It can get stuck on and prevent the generator from starting. Often the shutoff sensor gets stuck at the bottom of the crankcase.

It ensures the sensor will read “low oil” and the engine will refuse to start. This can be a major problem in an emergency when you need a backup generator to start right away.  


If your generator displays “low oil” and refuses to start despite the fact that it is fully charged, there are a few measures you that can take to bypass the sensor and get the generator running again. This may fully resolve the problem, but it may be necessary to get additional help and replacement pieces.

Often consult a specialist if you are unsure, either through the manufacturer or an engineer, who is familiar with the operation of generators.

Please learn to follow your owner’s manual’s safety directions, as well as the protective measures listed in this study. We hope this information was useful and that you now know how and when to bypass a generator’s low oil sensor.
