Remember, emissions testing is only required if your vehicle is registered in one of the designated emissions counties in Texas. If your vehicle does require an emissions test, our certified technicians will look at three primary areas:
Checking your dashboard for any malfunction indicators. This may appear as a “check engine” or “service engine soon” light or indication.
Making sure that the malfunction indicator light’s status and diagnostics trouble codes are in good operation.
Checking your vehicle’s OBD II readiness monitors.
Older vehicles that don’t have OBD II ports will have a manual emissions test with a reader connected to the vehicle’s tailpipe and measuring the emissions while idling.
