What is Code 89 on a Vauxhall Mokka?

Faulty Thermostat

A defective thermostat usually causes code 89. In some cases, a faulty thermostat may cause your engine to run too hot or too cold, which can cause the ECM to display a warning code.

The thermostat regulates the coolant temperature during engine operation. In order to prevent hot engine coolant from entering the radiator, your car’s thermostat closes when it’s cold.

The valves of a warm engine open immediately, allowing coolant to flow through the system.

Thermostats are prone to wear and tear over time, especially on Vauxhall vehicles. As the thermostat housings age, they can crack, allowing coolant to leak out.

There is a possibility that your Vauxhall Mokka will run hot if its thermostat housing is cracked or faulty.

Bad O2 Sensor

Using oxygen sensors, an engine’s exhaust is measured for oxygen content. Located before or after them are catalytic converters, which reduce harmful emissions.

After replacing the thermostat, if your Vauxhall Mokka still displays the code 82, one or both oxygen sensors may need to be replaced.
