Check engine light

My truck just threw a cel. Is there any way to get the code without a scanner?

Hi Schlava,

I think that if you put your truck in engineering test mode one of the screens will display active DTCs. Not sure though, and I currently lack a truck to corroborate this with.

I just got my first CEL.
I tried the engineering test mode but it shows CONTINUOUS DTCS not codes that come in intermittently.

So I took my 2012 350 to the dealership and they found something to do with the MAP Sensor. The tech reset and told me to come back for a more detailed trouble shoot if it comes back in. Which it did 15 minutes later! So I have an appointment 1st thing Monday morning...

What I'm getting at is take your truck to the dealer, @$$ pain? yes but they have to fix it if it's under warranty...good luck
