P0134 Oxygen Sensor Circuit No Activity Detected (Bank 1, Sensor 1).

If the engine seems to be running okay, I would replace the primary oxygen sensor and for the EVAP issues the most common cause for this is a bad gas cap or it has been left off. Here is how to change out the oxygen sensor in the images below. If the engine is not running okay, we can have other issues that caused this code. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem.
