Dashboard lights go out at will and engine lights show codes even after replacing sensors now 02 sensors not working . Look like this had been a ongoing problem for years now and Chrysler fails to address the problem. Please help myself and other pt drivers having the same problem.
Engine lite came on. Replaced recommended parts. Lite came off and on over a year or so with same diagnostic. Replaced same part in late 2013 and lite still stays on. I am told now it is the computer itself. Have been told this is a common problem for Pt Cruiser owners and that many replace the same parts I did and it is to no avail. To my best of recall it is the upper/in lower/out oxygen 2 sensor. With the computer (engine lite) causing this problem Chrysler should have a recall on it.
