Can do, can also mean an intermittant fault that just doesnt happen to be presesnt that minute.

Clear it, if it comes back, then its time to investigate  :y

Generally 3 common states:

PRESENT - ECU is currently detecting the fault (or in some cases has detected the fault during this session, but currently unable to confirm if still present)

INTERMITTENT - The fault has been seen to disappear then come back during this session. Often, status changes pretty quickly to PRESENT

NOT PRESENT (NP) - Fault has been detected 'recently'.  Can mean a present fault, but engine/ecu in a condition it can't check for it.

The definition of 'recently' can vary from this session to last 20 clean starts, or in one or 2 cases (particularly immobiliser codes), since codes were last cleared.
