OBD Model B no PID

[BrAjN]

Hi all, i got my obd2 mod B on arduino UNO, the problem is that only the battery voltage is working i tried to retrieve the RPM and SPEED but the UNO always display this value as 0.

i have tried on this cars:

MG ZR 2002 (ISO9141)
Peugeot 206 2003 (KWP not sure if Fast or 5kbp)

Any help would be really appreciated.

Thanks

ISO9141 is not supported. KWP2000 is supported.
