another important Channel to add is the Mass Airflow Sensor, not to be confused with the Mass Airflow channel which we will cover later. And shouldn't it be called a MAS and not a MAF (sorry couldn't help myself).

We want the Mass Airflow Sensor to show either 0 volts or 0 hertz depending on the units we have chosen, with just the key On, and the engine not running. Simple as that, does it show any numbers at all? Yes / No? If yes does it read zero. These are not bullet proof tests but they are designed to catch glaring errors and omissions.

Again just another readiness check.
