Check Engine Light
This light came on after about 2 hours of travel yesterday; we were scared, having never experienced this. We finally found a place to stop. All instrument gauges were normal. I turned the engine off and checked the coolant and oil levels; both were normal. I left a message for James T to get advice. He called about 1/2 hour later. That warning light did not persist after turning the key ON and did not return after starting the engine again. James said that means it is a Inactive code, Active codes will keep the warning light on. He thought it was probably a sensor connector and that we should go ahead a drive it; we did without further problem. His only suggestion was maybe sitting on the engine and disconnecting and then reconnecting the weather proof sensor connections. The Diagnostic switch behind the dash will only read Active codes. James said if it happens again we should take it to a shop that can read Cummin's codes and to NOT turn the engine Off until they check it. If the Check Engine light is Off they will have to drive it until it comes back on and will charge labor.
Anybody have any ideas or know how to locate the different sensor connectors?
Thanks, Dick
