What's the p2015 code Jeep Patriot?

The P2015 code means that there is out of range performance from the bank 1 intake manifold runner position sensor. This means that the air intake on the car is not going to be correct. This is important for making sure combustion in the engine is correct. You will notice shuddering when You are idle, and it may even stall out. There will also be less power when You are accelerating, so You will need to make sure You accommodate for this. You should take the car into the shop and have them take a look at it sooner rather than later. If You wait too long You may end up doing damage to the engine.
