Amber check engine light on

I find a piece of black electrical tape solves the problem.........at least that's how I solved mine

 

My freightshaker dealer that works on ours said a amber light needs attention, but dont freak out. A red light, best shut that truck down as soon as possible... take it for what its worth, 3rd hand advice over the internet...

 

Mine does that when pulling heavy loads in hills going east. Then it goes out when I come back to the Midwest.

Maybe it's a New Jersey proximity warning light.

 

Generally the engine light with nothing inside means it should get checked but don't freak out. The engine with the wrench in it is more serious. If you get the red light you risk imminent damage to the engine or it's about to shut itself down.

 

Lots of minor issues it could be, but more than likely has something to do with the DPF system. May have a clogged DP filter that needs special attention. Regardless, there is a code that will point you in the right direction once you extract the info

 

Is this a Cummins?.....I agree with STexan...probably DPF related..They have several sensors before and after the filter.
Also the DPF needs baked and cleaned about every 250k...

It should show any active or inactive codes if the yellow light was or is on.

 

Do what striker said and then turn up the volume on the radio. Usually solves the software problems.
