Hi. You need to clean the Mass Air Flow Sensor.
This is an easy job.
Get a can of throttle body or brake cleaner spray at your local auto parts store.
Open the hood, and locate the air filter box. follow the tube from the filter box towards the engine. Look for a small black box with 2 screws holding it to the air tube, Remove the wire connector and observe inside the sensor with a flashlight. You will see 2 small wires, and they will appear fuzzy or dirty. Spray the interior with the cleaner until the wires are nice and clean. Do not use compressed air, you will damage the sensor. Put it all back together and drive it.
This will def fix your issue. This is a vey common problem. If you do it yourself, you will save 70 + bucks.
Thanks for choosing FixYa, and a FIxYa rating for my assistance would be greatly appreciated.

SOURCE: Engine Light on got 3 codes
Fix the leak at the emissions system first. There is a small leak that the PCU detected. That could be the cause of the P0116 problem. Also the PCU detected a lean gas mixture because it is getting more air to the fuel system than gasoline. Start with the leak , then the Engine temperature sensor. I think that fixing the lek will "fix' the othe 2 problems. but it could be either one or all of them.

This is probably referring to problems with your bank 1 oxygen sensor. Without the vehicle make, model and year I can't tell you where it is located. However, if you replace your front oxygen sensor that should clear up the problem. Also, if you do replace it, I always run some fuel injector cleaner through a full tank of gas at the same time. Hope this helps!
