Footwell temperature sensor code
2015 E350 W212
My scanner shows code 911315 and N70B1. The sensor is showing a -58 F temp, and it's summer. Maybe that's the default short circuit or broken wire temp.
Is this the sensor that you bump into when replacing the cabin air filter on the passenger side? The wires look fragile if handled roughly.
Does anyone have the sensor or wire repair part number? It looks like 2128300872. Any words of wisdom, since this looks like a quick easy repair?
Everything seems to be working just fine on this 47K mile car.
Thanks!

That does help. I ordered a sensor and the wire repair kit, so that I have them in hand when I open it up. I will keep you posted.
Edit-I couldn't stand the suspense, and opened up the footwell compartment. That took a full 15 seconds.
The sensor was just unplugged! I nervously plugged it back in, and it worked perfectly. No shorts or a fire. The code 911315 went away, and I could track that vent's temps on my scanner now. Pretty cool to be able to do that.
Still, the N70 code, which looks like the overhead panel. I will have to figure out what code N70B1 means, unless someone has some insight.

Answer: OCP
Neither this Temp sensor nor the OCP host module have proven to fix the issue after swap...
I believe this has something to do with the serial LIN
which I have not nanaged to fix by eating a lot of my own dog-food...
