Land Rover Repair/Fault Code


Just in time for inspection...2004 Discovery SE.

Check engine light on.

Check for codes with "Bearmach, Hawkeye" scanner.  

Getting a "fault: 93 Evaporative Control System Fault Minimum Value Not..."

Not an expert by any means but way more than handy.  Any advice would be greatly appreciated.

The code you cite is not a a standard OBD code; you would need to look in the information that came with the tool to interpret it.  All I can say is the code relates to the evaporative control system, which regulates vapor emissions from the gas tank.  The code you have suggests the need for testing; it does not point to a specific part you can change.  Not all parts for the eval system are available; some are discontinued.
