The engine light came on in the 2011 a couple weeks ago. It was on for about a day and a half, and during that time I was doing a lot of idling and driving very slow. After driving at highway speed a little more the light went off. About a week and a half later, it came on again, and is still on 3 days later. I swung by Advance Auto and had them check it, and their tester said "Reluctant pressure low". Does anyone know what that means?

 

I would not take there reading as gospel. Do the engineer mode and check for DTC's and report back.

 

If it's "reductant" low pressure, you may have an issue with the DEF pump.

 

What was the code number?

 

Nothing in engineering mode.

Don't know the code number.

I think I'm just going to take it in. It has some oil leaks that I'm going to try to have fixed under warranty, this gives me an excuse to call.

 

keep us posted.

 

Good idea, deere55; let us know what you find out. How many miles do you have on your truck?

If I'm interpreting his signature accurately, it looks like approx 84,000 ?miles?
