ALWAYS check the body grounds first. Ground to the dash gages could be faulty, dirty, or just not tight enough to make a good connection.

How to reset the pressure monitoring system warning light on Mazda 3


Read the manual on the mazda site... it's very helpful. Have you changed tires recently? have a spare on?

"After adjusting the tire air pressures, it may
require some time for the TPMS warning
light to go out. If the TPMS warning light
remains illuminated, drive the vehicle at a
speed of at least 25 km/h (16 mph) for 10
minutes, and then verify that it goes out."

Gauges jump w/ acceleration & batt/charging light on


First, have the battery charged and load tested. If it does not pass load test, replace it. An alternator is not made to charge a battery. it's job is to maintain the current state of charge. By driving and attempting to charge it that way you over-worked the alternator and may have damaged it or the regulator. Once the battery is fully charged and in good condition, you will need to check the charging system for proper operation. If the gauge system does not return to normal, it will need further diagnosis to correct it.This isn't a "cure" but rather, what you need to do in order to get back to "square one". With the alternator running "flat out" trying to charge a dead battery it can put out over 15volts, possibly damaging the dash/body control module or computer.
