Weekend Project – Check Your Check Engine Light For $20

Modern cars offer a ton of on board self diagnostic  equipment to help point us in the right direction when things begin to fail. However it seems that most auto manufactures would prefer the diagnosis of the dreaded “check engine” light left to the professionals. I don’t believe this should be the case. If you own the car you should be able to diagnose issues and make decisions on how and where to have them repaired.


Fix your check engine light with a $20 ODB2 scanner

Cars have had some kind of ODB (on board diagnostic) system since the early 1980’s. I can remember a hack that allowed me to short a pin in the ODB port to ground on my 82 Buick that would allow the check engine trouble codes to “blink” out on the idiot lights.  There was no modern internet service then so it was still a quick call to my friend at the garage to look up the trouble code.

Today we don’t have to make a huge effort to find out what our car is thinking.  This simple ODB2 dongle supports all protocols and will transmit the diagnostic data directly to your phone via WiFi. Plus there is a wealth of information regarding the trouble codes on the internet.
