Brief check engine light on 2007 Columbia?

What part of the country you in?

 

check the coolant level. those trucks have to run high coolant level above the bottle sensor. the water pump draws so much in a pull. it can cause a low coolant light and shut down. run coolant level about 1-2 inches above the line. hope this helps

 

#### I’m if you wer in atl I could hook up Jpro software up to it for free.I’m in my last semester of tech school and we have a software we are allowed to use called Jpro

 

coolant level.

 

I had same truck/same engine and same set up. I also had the same issue. Try changing your turbo boost sensor. There is another sensor, I think its a manifold sensor or something, change that one also. It fixed my issue a few years back. Light would only come on in a hard pull such as going up a hill. Didnt come on all the time but, it did it every now and then.

 

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.

 

If his truck was anything like mine(mine was deleted and had same exact symptoms) it of course only flashed "25". I would remove the turbo boost sensor and clean the bottom of it and it would work also.
