Code B0521???

Just received the code B0521 for the Tachometer Signal Circuit Malfunction. Does anyone know of a quick fix for this. I went to Autozone and had them check my battery and alternator, both were fine, but the code and message (Charge system failure?) still appear. Just looking for possible answers.
TIA

what does your tach read?this fault usually sets if the tach reads over 7000 rpm's.

My tach reading is normal (1800). I haven't had a spike in my tach or driven it hard, lately. I was just driving home and the message charge system failure appeared and the code.
