## NHTSA's summary

Service NewsDue to On\-Board Diagnostic \(OBD\) regulation change starting with 2019 vehicles, American Honda’s Variable Valve Timing and Lift Electronic Control \(VTEC\) On\-Board Diagnostic monitors are now included in the EGR/VVT OBD Monitor Readiness status group. Due to some customer’s driving patterns, they may not drive in the fashion needed to operate the VTEC \(EGR/VVT\) that only operates above 5,350 rpm to run the OBD monitoring. Therefore, the EGR/VVT OBD monitor group readiness status is not set to “Complete” when the customer presents their vehicle to a Smog Check station for inspection.
