Yes — gasoline-electric hybrids receive a full smog inspection using OBD-II protocol only (no tailpipe probe), but the start-stop engine behavior often requires a 30-plus mile warm drive beforehand to set all readiness monitors.
- Hybrids use OBD-II protocol exclusively — tailpipe probe is not inserted because the engine may shut off mid-test
- Engine-off electric driving clears readiness monitors faster than on conventional vehicles — drive 30-plus highway miles before testing
- Prius Gen 2/3 inverter cooling pump failures can cause hybrid system faults that show as readiness incomplete
- Accord Hybrid, CR-V Hybrid, and RAV4 Hybrid have seen EVAP monitor reset sensitivity issues post-battery work
- Plug-in hybrids (PHEV) are NOT exempt from smog — they follow the same full inspection as regular hybrids
Per BAR hybrid testing protocol and OBD-II readiness monitor standards.
