Help!!! Engine Code Problems

[joneill1975]

I got an oil change on Saturday and afterwards poured in some "engine restore". Later on that afternoon the service engine soon light came on. The two codes are:

P0011 - IVT Control performance/Crankshaft Position Sensor/Camshaft Position Sensor - Bank 1

P0021 - IVT Control performance/Crankshaft Position Sensor/Camshaft Position Sensor - Bank 2

What could be causing this? Is there a problem with the oil (dirty, burnt)? Or is this a false alarm? I'm getting a code reader tomorrow and will clear the code to see if it comes back. I don't want to change the sensors out and have it come back immediately. Is there anyway to tell if it's a bad sensor or a true problem?

Does the car seem to be running okay? Smooth idle and revs strong to redline?

The car ran a little rough after I put some injector cleaner in the gas, but it's now running fine. I cleared the codes last night and they haven't come back on....yet.
