Just locate the connector with the white cable, in the front of the Engine and it lead you to the oxygen sensor. It has to be attached to the Pre- Cat
You need get a special socket for oxygen sensors. Disconnect the harness, use the socket to remove the sensor. Reinstall a new one. Tighten the sensor the proper torque. Put some dielectric grease on the harness, reinstall the harness. Reset the ECU.
in the exhaust manifold toward the firewall its the hard one!!!
