  Q: How to check the voltage of a Mass Air Flow Sensor on Mazda MPV?

  A:

  To measure the voltage of the four-cylinder engine, the voltage check of the airflow meter electrical connector should be checked by withdrawing the rubber boot, which exposes the terminals. Test the assigned terminals, beginning with the power supply on the Black/white stripe wire and maintain appropriate voltage connection on the airflow meter terminal connector, some of the tests will need ignition key to be in the ON position. In case the voltages are not correct, check the wiring harness. In the case of the burnoff control system, which is used to heat the hot wire inside the airflow meter to burn him off, disconnect the negative battery terminal not less than 20 seconds with the airflow meter output voltage out of range, then reconnect the cable. Turn on the engine until it reaches normal operation temperature, unplug the rubber boot of the airflow meter electrical connector and continue the engine running over 5 seconds at about 2,000 rpm in Neutral. Once the ignition key is turned to the OFF position, measure the voltage at a terminal G/O and make sure that it is 0 volts when the switch is off, followed by 8 to 12 volts at 1 to 5 seconds. In case of faulty readings, diagnostic the ECU in a dealer or repair shop; in case of correct reading, change the airflow meter. In V6 engines (1989-1995), be it that the airflow meter be removed, inspecting the area of the airflow meter on a crack or other forms of damage is also advisable; the measuring plate should move freely and completely open. Test the terminals with the measuring plate completely closed to ensure that there is the right amount of resistance; in case the readings are wrong change the airflow meter. In order to remove and install the airflow meter of all the engines, one will have to remove the air cleaner assembly, disconnect the electrical connector, loosen the hose clamps, and loosen the bolts in order to elevate the airflow meter out of the engine compartment or air cleaner assembly and then install the airflow meter back in its place.
