OBD and how to access
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!

1996 and later models are equipped with OBDII systems. Check the emissions label under your hood to be sure. OBDII requires a compurer reader to pull and reset codes. The Autozone stores in my area will pull the codes for free.

Re: Re: OBD and how to access
Thanks! I did go by Autozone yesterday. My check engine soon light flashes, especially going up mountains, or trying to pass some one. But as soon as I let off the gas, the light stops flashin and doesn't come on again. The man at autozone scanned it, but it passed. There is definately something wrong, and it feels like O2 sensors?!?! Any suggestions?!?!?

I have used EASE diagostics (www.obd2.com) while I am driving to detect problems. It is an expensive tool ($300), but worth while when you run into as many problems as I do. I have it connected to a laptop and recording specific data while driving. A second option would be the Data-Logger. This would allow you to record everything going on when you get the fault/check engine, and not need any other tools.
I prefer the laptop so the passeger can be checking all systems while driving. Again, not a cheap option, but worth it if you have access to a laptop computer. |

2001 Ram. I did the on off on off on thing and in the odometer section it said " P done" and gave 6 chimes. What does this mean?
Thanks, Bob |

Re: OBD and how to access
You will have a code for a cylinder misfire if the CEL is flashing. The fuel not burning in the misfiring cylinder gets passed into the cat and is burned there. This drives the cat temp way up and destroys the cat. When the CEL flashes, the engine is supposed to be shut off to prevent damge to the cat. That way, Chrysler might save on the cost of a cat.
