There is a silver box underneath the center console, just to the right of the gas pedal.
Pull off the plastic cover (it has two plastic fasteners. It will go back on).
Peel back the plastic film covering the screw.
Put the key in and turn the ignition switch on, but do not strt the car (all the warning indicator lights should go on).
Turn the screw all the way clockwise for two or three seconds and turn turn it back. Repeat just to be sure.
Turn the key off. When you turn the key back on the Check Engine light should be off.
Replace the plastic film over the screw and replace the plastic panel.

This code refers to the front oxygen sensor on Bank
1. The heated circuit in the oxygen sensor decreases time needed to enter
closed loop. As the O2 heater reaches operating temperature, the oxygen sensor
responds by switching according to oxygen content of the exhaust surrounding
it. The ECM tracks how long it takes for the oxygen sensor to begin switching.
It the ECM determines (based on coolant temp) that too much time elapsed before
the oxygen sensor began operating properly, it will set P0135.
Repair short or open or high resistance in wiring harness or harness connectors.
Since you have already changed out your O2 sensor (as long as you used to OEM replacement and not the "Universal" replacement) you should not have to replace it again. You might check your thermostat to part of the time it takes for the O2 sensor to start switching being based on coolant temp, if your thermostat is not operating properly, it could cause the coolant temp to take longer than what is considered by the ECM to be normal.

According to the Haynes manual it is under the intake manifold, Upper and lower intake manifolds must be removed for access. If you go to Auto Zone, they have the sensor and can give you the step by step instructions to replacing the knock sensor with common tools. Good luck and hope this help.

If the car is pinging you will set a knock sensor code.'
This comes from bad gas and running lean., You really need this professionally inspected to rule out the basics. I have seen alot of nissans with the knock sensor code stored but the light is still off.
Fill up the tank with high octane chevron and some techron injector cleaner and clear the light. If it stays off for a couple days then go get it inspected. Even if the code is stored it will still pass as long as the light is still off and the monitors have run.
