The USEPA and state
authorities have generally found that OBD II systems are more effective in detecting
emission-related malfunctions on in-use vehicles compared to existing Inspection and
Maintenance (I/M) tailpipe testing procedures. Current Smog Check data indicates that
vehicles are more than twice as likely to fail an OBD II-based inspection than the
required tailpipe emissions test.
