Terrain Management / AdvanceTrac System Errors

[peterk9]

So my 2012 explorer just lit up. Terrain management stopped working, traction control stopped and service advancetrac kept popping up on dash.
No codes and my battery and alternator are fine.
Now it's gone and everything is fine after I let it sit for a few minutes.
Should I be worried?

My 2012 Has been getting the Terrain Management System fault quite a bit latley- was there ever a recall or anything done about this? Seems as those this is a pretty common issue, Cycling the key works at times, others the vehicle must sit for a bit. HELP PLEASE!!!!

Welcome to the Forum.
I believe that the fault is an indication that something is failing. There is no Recall since they are only issued for safety-related items. I don't believe anything else was issued either unless it is mentioned in this thread.

Thanks for the welcome!
This is most assuredly a saftey item. When the fault comes on the vehicle loses power.
Thanks for the reply

Hey all,
I've searched the threads and didn't find anything specifically about replacing an abs wheel speed sensor so here we are. I recently had my abs, Trac, tms, and downhill assist lights illuminate in my 14 Sport and Forscan confirmed that my LR wheel speed sensor was the culprit. I swapped it out for a new one *not OEM* cleared DTCs and reset modules in Forscan but the lights keep coming back. Should I suspect the sensor is the issue since it's not from Ford or am I missing something? Anyone have experience with this?
Thanks in advance.

Hi Janob09

Front wheel speed sensor is mentioned - go back one page to Brokanic's post.

I have a 14 Explorer sport and my Left Front Wheel speed sensor popped out causing the same issues and I just put it back in and bolted it. Reset the codes and the problem was solved. If that was your only fault and it's still persistent then it might be the OEM sensor. Have you had a look at the OEM sensor compared to your old one to see if it's a good match for fit/finish?

Hi Brian,
The replacement sensor looks nearly identical to the OEM unit so I'm leaning away from a compatibility issue. Everything was very secure when I removed the OEM sensor and everything was intact so my next move will be to check the hole the sensor goes into for debris and next up I'll return the new sensor and get one from Ford...
