My recent purchase of a 2007 E350 just threw up a Check Engine light. The code is P0022.

This happened right after I put in some gas.

I was told to change the Camshaft Position Sensor, which I did one Bank #2 (second sensor from the right I was told.)

I was told to check the oil since the time is coming up for an oil change. The oil is BLACK, but still above the minimum. I am going to do an oil change.

Is there anything else I should be aware of?

The car runs fine, no noises, no decrease in gas mileage, no stalling, no stutters, just a good running car.

Thank you in advance.
