Hi all, is there any easy way to access the OBD codes for a 1998 Dodge Ram 1500 4X4? It feels like the oxygen sensors are faulty (I had that problem with my 1995 & 2001 Plymouth Neons). on my previos cars, I could access the Self diagnostics by turning the ignition switch on-off-on-off-on and it would tell me the codes to the problems that the cars were having. Is there something like this for the 1998 Dodge Ram trucks? An help is greatly appreciated!
