Why does my Onan diesel generator shut down?

I have a 7500 Onan diesel generator that runs for a minute and shuts down with a high coolant temperature fault code, but the coolant level is good and nothing feels hot, just warm. I went ahead and changed the fuel filter and air filter hoping for an easy fix but the same problem exists.

Can a bad coolant sensor cause a car to not start?

Some cars use the engine coolant temperature sensor to control the electric cooling fans. You have two separate temperature sensors for the fans, dashboard gauge, and engine management in most cars. However, if your car has a single sensor, a bad engine coolant temperature sensor may result in your fans won’t start at all.

Why is a coolant temperature sensor so important?

A coolant temperature sensor is especially important for the optimal performance of your vehicle. While you drive your vehicle, the engine goes through continuous combustion. This can make it very hot during the drive, especially during daytime driving.

How to read Onan generator fault code Code 58?

Code 58 – Exhaust Gas Temperature Shutdown What causes this error code is a lean fuel supply, restricted exhaust system, bad ignition system, bad heat sensor, and other issues. To keep your warranty valid, you need to take your generator to your Onan dealer for diagnosis and repair. Code 81 – Exhaust Gas Temperature Sensor Open

What does code 27 mean Onan battery controller?

The manual states that the only solution is to go to your authorized Onan dealer to rectify the issue. Code 29 – High Battery Voltage

What’s the name of the coolant temperature sensor?

Coolant temperature sensors are also known as engine coolant temperature sensors or ECT sensors. The principle working of this sensor involves the use of an electrical resistance which measures the temperature of the coolant.

How can I tell if my coolant temperature sensor is bad?

To diagnose the coolant temperature sensor, you need a repair manual for your car model to find what measurement values you should expect from the coolant temperature sensor. Connect an OBD2 Scanner and look for related trouble codes. Check the live data to see the temperature from the sensor.
