Yes, the OP's question has been answered.
Most Emission related problems are not that expensive or difficult to repair. More often than not, the sensors are not the problem, but shops/Pros love to throw sensors at the problem. Unblievable how little most shops/Pros understand about OBDII. I have been dealing with this for a LONG time and rarely do most problems amount to more than vacuum leaks or basic maintance problems.
BUT, everyone should have an OBDII smart phone/tablet App.
Torque is not recommended for many reasons.
Get an OBDII smart phone/tablet App and interface, typically $30 or less. These Apps are usually best for drivability issues and they support Emission Readiness Monitor Status, Freeze Frame and Live/Realtime data. They are also great for Logging data for review after the car has been driven and can really help find unusual problems.
Android - Touch Scan for $5.00 and ELM327 OBDII to Bluetooth interface.
iProduct - OBD Fusion for $9.99 and ELM327 OBDII to Wifi interface.
Some people prefer to have an extension cable to keep the interface away from their feet.
Something like these cables are often of interested:

I usually suggest getting the OBDII interfaces from Amazon if you are located in the US/North America. Make sure you choose an interface that indicates that the order will be "Fulfilled by Amazon" otherwise you may be waiting for WEEKS for an interface to arrive from Asia. Ebay is another option, but pay attention where the interface will be shipped from, again weeks for an interface from Asia, so if you can wait and want to try to save some money, go for it, but if you need an interface soon, choose wisely.
