Having problems with your 2003 Toyota RAV4 ?
2003 Toyota Rav4 low voltage light is on after changing Mass Air Flow Sensor, alternator, and battery is good as it's 1 year old. Battery was checked and is good. Car is still stalling and voltage light is still on. Took it for free diagnostic at Auto Zone for a second time and code reads Mass Air Flow Sensor. Sensor has been changed. What else could it be?
Did you have the computer reset after the part was changed? That is what you need to do. It may also take some time for the computer to relearn everything. Was it a bad maf sensor or a probem in th circuit itself? There is a difference. If it was just the sensor and you replaced it, then reset the computer and let it relearn. Make sure your charging fuse and relays are good as well as making sure the ground cables and battery cables have clean connnections and are tight.
