WHERE ARE OTHER SENSORS RELATED TO THE SPEED SENSOR @ TRANSMISSION?

1999 Infiniti Q45 • 250,000 miles

When I bought car 3 codes were on it knock sensors and speed sensor i
changed knock sensors and speed sensor @ thans. But the speed sensor code comes back, forgot to mention. The speed odometer is at 10 on standstill
and the rpm at 10 also the code is p0500a is this at wheel if so how will I determine witch one

You need a scan tool to verify a signal from the trans is reaching the pcm. If it is, you have a failed dash cluster. If not then the reason needs to be determined.

A shop has the actual scan tool you need. Get some help with this

Does not mean anything. Each works independent of each other.

Yes, you can but it needs to be verified with a scan tool, not a guess. It is expensive if it is the cluster

Has nothing to do with the speedometer, sorry, that is a separate issue
