Maf Sensor Voltage Chart

Maf Sensor Voltage Chart – The mass air flow sensor (maf) has become a standard part on most engine applications and is mounted in the intake air stream just past the air filter. The mass airflow (maf) sensor reads the airflow entering the engine. Here is a fast and accurate way to track a maf’s performance and output to. With a lab scope a hot wire mass air flow (maf) sensor with frequency output is measured under the following conditions:

This type of signal is common with hotwire and older flap style sensors. The mass air flow sensor measures the amount of air entering the engine or the air flow. When performing these tests, try checking for a voltage signal; A normal maf sensor reading voltage can vary depending on the make and model of the vehicle, as well as the engine conditions.

However, in most cases, a healthy maf. Normal output voltage of a map sensor should be about 4.5 volts or so with key on,. The vane moves in proportion to the airflow.

Generally, the mass airflow sensor get 12 volts when the key is in the on position. If you are able to view the maf sensor signal voltage on an obd2 scanner, then do so. Check the maf sensor and measuring elements for damage.

On a vehicle with a cabled throttle this test works quite well. Making sure the maf sensor is getting 10 to 12 volts: However, there is a flaw with this test when.

A general rule of thumb is voltage should exceed 4 volts. Depending on your maf sensor, your voltage reading should be between 0.60 to 0.80 volts at idle. Use your service information troubleshooting guides or ecm terminal voltage charts to determine where the airflow signal terminal voltage originates.
