In a DTC code what is the meaning of the portion of a code which states; range/performance, for example: PO341 is a Camshaft position sensor circuit,range/performance problem.
This is what is displayed in the OBDII codes list.
Thanks for your help

that means the sensor is not performing the way it should. say it should have 900 ohms when tested with an ohmeter, yet it is only showing 200 ohms, that means it is not in its correct "range".
