SOURCE: Check Engine Light 1996 Nissan Maxima

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.

SOURCE: Check Engine Light - O2 Sensor - bank 1 running lean

you should have three oxygen sensors on your car, one for each bank of three cylinders; should be towards the Y pipe on each exhaust manifold. Additionally you should have one on the exhaust pipe before the cadilitic converter.

SOURCE: check engine light on 2003 toyota tacoma, O2 sensor?

An O2 sensor code is a tricky one. It could mean SEVERAL different things, and I know how bad it sucks to hear this, but your best bet is to take it in and have a diagnostic ran on it at either a dealer or a good mechanic shop with a computer they can hook up to it. I had an "O2" code come up a while back on another car I used to have, and literally spent weeks and hundreds of dollars trying to fix it, and never did. Finally out of desperation took it in, paid the $90, and they found the problem and fixed it in like 30 minutes. Something I would have never even thought of was causing it (can't remember off the top of my head). After that I stopped wating time and money on check engine lights. One comes on in my car, I take it to have it ran for free at and auto parts store just to make sure it's not a loose gas cap or something, just to get an idea of what I'm looking at, then go and make an appointment to have to hooked up to a diagnostic computer to track down the problem. Good luck, and hope this helps save you some time and money.

Something odd about what you posted. An engine that is running lean shouldn't be using a lot of fuel. Lean is when there isn't enough fuel going into the engine. Two other sensors that regulate fuel flow are the map sensor and throttle position sensor. Temp sensor generally would cause a rich condition but I'd test that too. Be sure to check for vacuum leaks at the manifold and lines as well as fittings... A vacuum leak will give the O2 sensor a lean reading...seeing that, the computer will try to compensate by adding fuel. Clearing codes can change the way it's running but as soon as the computer runs through it's internal diagnostics it will turn the light back on if there is a problem.

My check engine light came on it said P2626


This is an O2 sensor failure with the sensor located in the manifold. The associated heater probably failed causing the sensor to fail.

More likely something else is going on. If you had an O2 sensor issue, I would expect a check engine light...read those codes and you will knwo where to go next...

When an O2 sensor fails, the system goes into a limp home mode, and esentially runs poorly, again look for error codes.

O2 sensor


are you sure that it is still the O2 censor? are you assuming because the check engine light is still on? because you have to reset it after fixing something you just disconnect your battery completely for a bit like 15mins and then reconnect it and the light should go away.

Check engine light on.


Replace O2 sensor. They have to be really hot in order to read right. Did you ensure to drive around a good 30 min to make it hot?
