Hi, need your help, my red light comes up on my dashboard. According to the
Scanner, the code is P1131.
I would like to know where the upstream Bank 1 sensor is located.
If possible a diagram would be very helpful.
Thank you, Kenny

It is accessible from under the lower engine splash shield under the front of the vehicle.
I have attached a picture that should help you locate it. You can either use a box end wrench after cutting off the old connector, or use the special tool that you can pick up at most parts stores.
