FAQs
Why would My Vehicle Fail a Smog Check?
The most common causes of a failed smog inspection are:
Incomplete OBDII readiness monitors
A check engine light or malfunction indicator lamp being illuminated
Aftermarket parts that are not approved by the California Air Resources Board (CARB)
Engine performance or emissions-related problems
California’s Smog Check Program is designed to verify that your vehicle’s emissions system is functioning properly and that the original emissions equipment has been properly maintained.
At Broadway Automotive, we perform a complimentary OBDII pre-check on all 1996 and newer vehicles to help identify common issues before the official inspection begins.
What Are Readiness Monitors?
Modern vehicles constantly perform self-checks on their emissions systems using the vehicle’s onboard computer, commonly called the PCM or ECM.
These self-tests are known as readiness monitors.
Each monitor checks a specific emissions-related system — such as the catalytic converter, EVAP system, oxygen sensors, or EGR system — while the vehicle is being driven under certain operating conditions.
When a monitor completes its test:
It is marked as “ready” if the system passes
It may trigger a diagnostic trouble code (DTC) and illuminate the check engine light if a problem is detected
If too many monitors are incomplete or “not ready,” the vehicle can fail the smog inspection even if the check engine light is off.
This commonly happens after:
A dead or disconnected battery
Clearing fault codes
Recent repairs
Long periods without normal driving
Because every manufacturer uses different drive cycles, some vehicles require additional driving before the monitors can complete and the vehicle is ready for testing.
