Need help w/Sensor location and P111E code

[blamkin86]

Afternoon all - I have not been on here for quite some time (like a year) but could use a boost.

 

This morning, I added some more Baja lights to my 3500HD AT4. I used the Upfitter switches and didn't really hack into anything. I did use a fuse splitter to trigger the lights with the high beams.

 

I had the grill off for the install. When I got it all done and back together, I got a P111E sensor error and the dreaded "Reduced Engine Power" message.

 

This is something I've just done, but I have no idea where to start looking.

 

Any idea where the coolant or ambient temp sensors are?

All of my work was either behing the grill, or in the fusebox in front of the brake booster, or in the LF Fender area.

 

I didn't hack any wires, I thought I did a good job. Obviously I pullled too hard on something and there's a ground or sensor I've pulled loose.

 

Help!

OK I buttoned it up, cleared the code and drove around the block.

 

The gauges say 185* for coolant temp. And the reduced power and check ending light are cleared on the dash.

 

But the reader still says P111E and it does feel a little down on power.

 

Any thoughts are appreciated.
