mrwitty_1 Posted August 23, 2006 Share Posted August 23, 2006 Can anyone advise of a low cost reader that will show real time inputs from the ECM ? I would like one that will be able to read inputs from the O2 Sensor, Coolant Sensor etc. I have a 0420 code that keeps returning and would like to see if it is a lazy 02 sensor or a truly bad cat.

Also even if it is not, your going to replace the O2 sensor with the new cat anyway, so you really dont loose any money. Also you can rent one from autobarn for a few days that will show you real time nipper Link to comment Share on other sites More sharing options...
