How do you check corsa air flow meter?

To check the airflow meter on a Corsa, first ensure the engine is off and disconnect the electrical connector from the airflow meter. Then, inspect the wiring and connector for any visible damage or corrosion. Using a multimeter, measure the resistance across the terminals according to the specifications in the service manual; if the readings are outside the recommended range, the meter may be faulty. Lastly, you can also perform a functional test by monitoring the output voltage while the engine is running, ensuring it responds appropriately to changes in airflow.
