My V70 shows the following DTCs under a Heading of Cl:

Cl-132 RPM Signal, Signal missing
Cl-211 D+ Signal, Signal missing
Cl-221 VSS Signal, Signal missing
Cl-121 12 PULS VSS out, signal short to supply
Cl-124 RPM Signal, Signal fault
Cl-222 VSS Signal, Signal fault
Cl-113 Fuel Sensor, Open circuit.

The vehicle runs fine but continually throws these codes.
Where can I find info on these codes?

Thanks to all.
