I need to change the bank 1 sensor 1 oxygen sensor?

Hi,

Replacing the sensor isn't too hard to do. The only issue that may arise is getting the old one out. They have a tendency of corroding and rusting in place. Take your time and make sure the tool you are using fits properly.

To get you started, here is a link that explains in general how it's done. You can use this as a guide. It is more detailed than the manual directions.

If you look below, I attached the directions specific to your vehicle for replacement. Also, I circled the one you are looking for. It will be before the catalytic converter on the driver's side.

When you install the new one, it is a good idea to use an anti seize on the threads in case you have to replace it again in the future. Also, use dielectric grease on the electrical connection to prevent corrosion.

I hope this helps. Let me know if you have other questions.

Take care,

Joe
