If your OBC is reading a temperature of -40F, the temperature sensor is probably missing, or has a broken wire. I would find the sensor, behind the front spoiler, on the left side, and I would short the connector pins with a bent paper clip. The temperature reading should shoot up to well over 100F. If it does, replace the sensor.

I assume the MPH you refer to is the AVG MPG button. If so, it is reporting your average speed. You can hit the SET-RES button to throw out the old data.

I have the same problem, it is reading -40F, plus the mph on the OBC is set to 37.5 mph, anyone know if this a sensor or could it be the OBC itself?


Any info on how to reset the temperature display for the OBC would be appreciated. It was 14 degrees here in Boston this morning but my OBC temerature displayed 139 degrees.
