B) How to Test the MAF Sensing Element for Continuity Now, connect your meter's black probe to the ground on the connector terminal (on the side going to the computer) and the meter's red probe to the battery's positive (+) terminal.If not, you may have a fault in that part of the circuit between the electrical connector and the car computer. Your meter should read between 10 and 13 volts, close to battery voltage.Turn the ignition key to the ON position, but don't start the engine.Connect your meter's red probe to the connector power terminal (on the side going to the computer) and the meter's black probe to ground (this could be on the engine block, an unpainted bracket, or the negative (black) terminal on your car battery).Set your digital meter at or close to 20 Volts DC (direct current).A dirty, burnt, contaminated, or loose wire will interfere with the sensor signals. Gently pull on the wires to check for tightness. Visually inspect the electrical connector and terminal for dirt or damage. So even if you don't have this information at hand, go ahead with the tests anyway. Sometimes, you can identify these wires by testing them as described later. Check your repair manual, ask at your local auto parts store, or search online for this information. Identify the power, ground(s), and signal wires on the electrical connector.If you use the latter method, wrap the pierced wires with electrical tape when you're done with the tests, to prevent rust from creeping into the wires. If not, you'll need to pierce the wires using a pin when conducting your tests. To test the MAF sensor, you'll need to have the electrical connector plugged into the sensor.

If you have difficulty locating the sensor, look it up in the vehicle repair manual for your particular vehicle make and model. Look for an electrical connector on the air duct right after the air filter housing.On some models, you'll find it inside the filter housing. This could be a small block or a cylindrical section mounted as part of the air duct. Usually, you'll find it between the air filter housing and throttle body. First, open the hood of your vehicle and locate the MAF sensor on the air cleaner assembly.Now that you have a broad knowledge of how an airflow meter works, you are ready to test the MAF sensor.
