I recently purchased an ELM 327 OBDII device to diagnose an issue i had with my truck. This device plugs into your OBDII port an Bluetooth's the information to your phone. So once you download a compatible app such as OBD auto doctor ($9.99 full version). You can watch your gauges on your phone. Perfect for the sonic that doesn't show water temp, intake manifold temp, battery voltage, real-time mpg and more!
Heres some real-time screenshots i took while i let my G/F drive
You can pick which sensors youd like to view, and watch the numbers live.
My total investment was less than $20 with purchasing the full version of the app which works as a code scanner/clearer
Here's the device i purchased, it looks like the seller is out of stock, but youll find any by searching "ELM 327" on ebay. Please note if you try this make sure its being shipped from America so your not waiting 3 weeks on a china e-packet!
