Exactly what type of engine do you have in your 2006 Nissan Altima? I've looked at the picture that you have posted and i can't figure out what that part is since its missing in my engine and i got the 2.5 S model. All i see there is the coolant sensor and the Camshaft position sensor. Hopefully someone on this forum will locate it for you soon.

Looks like the harness connectors for the front O2 sensor to me.

That is the connector for the air/fuel sensor. Similar to an oxygen sensor. Depending on the year of your vehicle you will either have the a/f sensor or an oxygen sensor.

Pls explain further, do u have a pic of the a/f sensor?

The air/fuel ratio sensor is the same exact sensor as the oxygen sensor, not sure why they use two different terms for this sensor to be honest with you. Here are two pictures to show you the exact location and sensor type.

Air/fuel ratio sensors look a lot like O2 sensors, but they aren't exactly the same. Air/fuel ratio sensors have more integral circuitry and work a little differently. They also don't show as great of a variation in signal waves when monitored with a scantool as oxygen sensors so.

So guys, tax for ur feedback, however I wud like to know where d front oxygen sensor connected to the exhaust manifold connects to in the engine compartment.

When you pop the hood and look down you're staring at it. The heat shield may block your view a bit. Disconnect the harness first before loosening as the wire will twist. You need the deep O2 sensor socket. If seized, spray with PB Blaster and wait 5-10 minutes and should come off easy. I suggest NGK or Bosch. BTW- Robert Bosch GmBH developed the O2 sensors in the '60's and Volvo was the first to use it in 1976.
Air Fuel Ratio Sensors and Oxygen Sensors are similar in that they both employ the Stoichiometric principles ( a branch of Chemistry). But they differ in the way the're made and operating characteristics. A/F Ratio Sensors: It operates hotter at 1,200F. At stoichiometric point of 14.7:1 (ideal A/F ratio and ECM base point value) the voltage reference is 0. In rich condition the voltage reference is -3.3 volts (negative), and in lean condition the voltage reference is positive 3.3 volts. It operates in wide band thus more faster, accurate in detecting the ideal A/F ratio. You cannot measure the voltage output directly. The manual suppose to have a conversion table. May be CONSULT can do it directly. Perhaps "mpe235" or "smj999smj" can confirm this. Oxygen Sensors: It operates at 750F and considered to operate in narrow band. At stoichiometric point, the voltage reference is 0.45 volts. In lean condition it will be below 0.45V and above up to 1.0v will be in rich condition. |

Depends what kind of part you are talking about purchasing. When it comes to air/fuel sensors and oxygen sensors, I would not recommend used parts. Purchase a new one and avoid "universal sensors" that have you cut off the old sensor and splice in the new. Nissan sensors can be expensive. As suggested earlier, Bosch and NTK (same company as NGK spark plugs) are very good. I use a lot of Denso sensors and they are very good as well.
For genuine Nissan parts, try: 1stAAANissanParts.com For aftermarket parts, try Rockauto.com For used parts, try: Car-part.com For downloadable service manuals, try: http://www.aubreyandcharles.com/ServiceManuals/ |

So are you missing the connector harness that connects to the air/fuel sensor for your '06? How is your car running so far? Those sensors connect to another harness that goes somewhere towards the firewall i think. Since i have two oxygen sensors in my '03, i have noticed the harness connects to a bunch of other wires that are bundled together coming from other places. Not sure exactly how you could be missing this in your car, if that is what you are asking.
