What does a code 89 mean in a 2012 Holden Barina?

Answered by CarsGuide 13 Jun 2025

The answer to this will depend on exactly which model Barina you have. In some models (typically earlier ones) the code is simply a servicing reminder to make sure the owner knows maintenance is due.

But in some versions of the Barina of this era, fault code 89 usually relates to a problem with the car’s thermostat. So don’t drive it any farther as the faulty thermostat could cause the engine to overheat with catastrophic results. Have a mechanic check things out and see if the thermostat is indeed faulty. If it is, it’s a relatively cheap fix, certainly compared with the cost of a new engine.

Sometimes the code relates to a switch in the thermostat that is responsible for switching on the car’s electric fans, but either way, it could lead to overheating. Don’t ignore it in any case.
