Yamaha twin 250 with same sensor problem on both motors

[mrod3222]

I have twin 2007 F250 and the YDS is giving me a code 24 Cam position sensor on my port motor and on my starboard motor im receiving error code 71 cam position sensor (STBD in) ironically both sensors seem to be the same part number. 6P2-85897-00-00.

Could it be posible both sensors went bad?

I replaced all batteries and checked connections all seems good.
