Hi guys I checked my Engine codes today and I got a 5 and a 6.

5 is a O2 Sensor
6 is a RPM signal (Crank Angle Pulse)

I know what the O2 is but how do I know which one is bad or should I just replace both.

But #6 I have know clue what and were it is.

I checked the codes at this website:http://www.troublecodes.net/Toyota/
(yes i kno it is for Toyota i went there becouse the Lexus one started at 12)

Any help is appreciated.
