New Readiness Monitor Standards for OBD System Functional Inspection

A vehicle will FAIL a Smog Check if:

Gas Powered
1996 – 1999 : If 2 or more monitors are incomplete

Gas Powered & Hybrid
2000 – Newer: If any monitor other than the Evaporative system monitor is incomplete.

Diesel Powered
1998 – 2006: If any monitor is incomplete
2007 – Newer: If 3 or more are incomplete

Sometimes, readiness monitors will not set because of a broken emission control system component. The Owner’s Manual often contains drive cycle information to achieve monitor readiness. BAR has found that certain vehicles, including the vehicles listed below, may have difficulty completing all monitors during normal driving:

  • 2000-2001 Nissan Maxima
  • 2000-2001 Infiniti I30
  • 2000 BMW 323i
  • 2004 Ford E350 Super Duty (5.4L)
