So I went to get the Charger state inspected today and it failed because the OBD "wasn't ready". Neither I nor the used car dealer I bought it from a month ago disconnected the battery nor did any electrical work on the car. Some members say that if the check engine blinks after 10 seconds of turning on the ignition means that the car needs to be driven more trips to make the OBD ready. Mine is blinking so that may be the case but I've driven it more than 400 miles in multiple trips in the past month. Also, the used car place said that since the car has a Whipple supercharger with a new aftermarket PCM that the oxygen sensors may have been turned "off" making the car fail the inspection. Does anyone know how to access the PCM and see if the oxygen sensors are turned on or is this something only the Dodge dealer can do ? Any suggestions would be appreciated ?
