195° is the stock temperature setting. He should have printed you a read out of the SES code (DTC) that you threw. Do you know what the code was, number wise? What modifications have you performed if, any?
A temperature too low will cause your SES light to activate.

Are you the original owner? 
Maybe the previous owner installed a 160° t-stat which will usually set the SES light. The stock t-stat is 195° and a good upgrade is the 180° t-stat made by JET. I have never set the SES light with my 180° t-stat. 
If the engine is running too cold the emissions will be higher and this is why the SES light is turned on.
