I’m having trouble getting an appointment with a mechanic so I’m hoping someone here can help me out. I have a 2007 freightliner Columbia with a 14 L Series 60 with a full delete. Once or twice a week when going up a hill at approximately 15 RPM I get a check engine light that lasts about 30 seconds then shuts off.Is there anyway to check what this is, and do you guys have any ideas on how to troubleshoot. thanks in advance.
Brief check engine light on 2007 Columbia?

Doesn’t your Truck have a self diagnosis (overide) button? Key on, push and hold button. Count the yellow (stored) flashes or red ( active) flashes.

I’ve had a similar problem. It was caused by the fan coming on, and blowing the coolant sensor plug. Caused it to wiggle and eventually an intermittent break in the wire. New pigtail, and secured better fixed it. Best to get a code, if there’s one logged. Can also get a code while it’s active. Beats guessing which sensor or wire.
