Hello! I recently bought a ‘13 SXT, 2.0 auto, to drive as a commuter car to work (I drive 150 kms a day, and the truck is a bit to harsh on gas for that!). The car has 190,000 kms (118,000 m) on it.
Its in real nice shape and runs/drives well, but I’m having a few issues I can’t sort out (or don’t know where to start looking!).
- Speedometer shows I’m going 5 kph faster then I am
- doesn’t show proper tire pressure at random
-doesn’t calculate gas mileage even remotely close (will show 45 mpg, but the math works out to low 30’s, which I think is terrible for a little car like this!) happens consistently
- I get a code every week or so, P1D73. Scanner shows it as Heat Pump Temperature Sensor 'B' Temperature Out of Range Low, when I google it with my car, it comes up as active grill shutter performance, which one is correct?

Any help with these is greatly appreciated!
