Video tutorial

Cleaning the mass air flow sensor, also known as the MAF sensor, on a Toyota Yaris is not a frequent task, but if necessary, it is good to know how to do it because the cost at a garage would be no less than £20, while doing it yourself requires only a cleaning spray costing about £10 that lasts for years.

The MAF sensor is located in the engine bay, right at the entrance of the air filter: remove it by pulling it out after disconnecting the electrical connector and removing the two screws.

After cleaning it with the appropriate cleaner, allow it to dry for a few minutes before refitting it.
