General Smog Check

Will TPMS Light ON Pass The Smog Test in CA?

The TPMS light on my SUV is flashing. The tire center told me the battery in few of the tire pressure sensors went dead after a tire rotation. Will I pass the smog test with the TPMS light on? I am in California. Thanks!


The TPMS (Tire Pressure Monitor System) will not cause a smog check failure. The TPMS light can be ON and a vehicle pass the smog inspection. It is not uncommon for vehicles to have an illuminated TPMS light due to low battery levels in either or all of the tire monitors, including the tire monitor of the spare tire.
