    My Check gauge light came on then my speedometer started pinging then I noticed my battery gauge went from 14v to 12v. I replaced the speed sensor a few days ago and it started doing the same thing again this morning any ideas??

    Welcome @Truedark1 ! Auto parts stores like Advance Auto offer free battery/alternator testing. While you're there get the engine codes read and post them.

    Well she made it to O’Reilly for a battery test and tested the alternator. Battery was good just needed to be charged and the alternator was bad. I also had them scanned the system and no codes came up. New alternator put in and the voltage gauge went up to 13.5 so will see!!
