My wife's 2016 1.5 turbo has lately started throwing P0011-00 intake camshaft position system performance and P0016-00 crankshaft position not plausible codes along with a P0826-00 up and down shift switch circuit codes. If I clear the codes, it will go for days and then then pop up again. The same 3 codes and this has happened probably 5 times now. I have ordered new cam sensors which I hope will fix the sensor code issue and they look pretty easy to change. But a) why in the world does the P0826-00 up and down shift switch circuit code set with these cam codes and what the heck (and where can I get a replacement) is an up and down switch? I've looked on all the normal parts sites and the closest I can find are shifter assemblies that don't specify whether they include any switches. Thanks for any help! Wife is not happy with this vehicle as it has been troublesome since we purchased it.
