Possible Speed Sensor failure but need advice

[jfoj]

Start with a generic OBDII tool.

Smart phone/tablet Apps are very good and cheap.

Get an OBDII smart phone/tablet App and interface, typically $30 or less. These Apps are usually best for driveability 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. Logging is very helpful for the less technical to pass date on for more advanced users to offer comments.

Android - OBDFusion formerly known as Touch Scan for approximately $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 or in your specific Region/Country. 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.
