2013 Mazda3 Speedometer not working, p500a error...Help

[Royx]

Hi, I have a Mazda 3 2013 skyactiv 6 speed manual transmission, the speedometer stopped working, the power steering ligth comes out and in the scanned show p500a and it says that low voltage we bought a new alternator and a new battery it keeps doing the same problems, it says that it doesn’t have communication with the abs wheel speed sensors. Plus we’ve been looking for the transmission speed sensor we haven’t found it anywhere in the transmission

@Royx Check all grounds. Then check all power connections. Look for damaged wiring.

I assume you mean a P0500 code? And not a "P500a"?
