      i was wondering where the oxygen sensor was located at on a 1985 pontiac parisienne.(v8 305)

        The Oxygen sensor (Denso Oxygen Sensor Direct Fit - Part No. 234-1001) on your 1985 Pontiac Parisienne is in the exhaust pipe system. Start looking in the exhaust system, starting up by the exhaust manifolds and work your way towards the muffler. There will not be any after the muffler. It is about 3 inches long and screwed into the exhaust pipe with a electric wire on the end of it. For any further assistance please feel free to call us at: 1-877-238-2623 or visit the nearest Advance Auto store and one of our representatives will gladly assist you with any questions or concerns you may have.

    • Q:

      Number of and location(s) of Oxygen Sensors for an '88 Chev Cavalier Z24?
      Asked on 10/7/2011 by Big Joe from Mifflinburg, PA

      1 answer



        1. Locate the oxygen sensor that needs replacing. If you're replacing the front one (upstream), you can access it in the engine compartment by lifting the hood. If you are replacing the rear sensor (downstream), you'll need to lift the Cavalier's front end with the floor jack and support it safely and securely onto the jack stands. The front sensor is located in the front lower center of the engine and screwed into the header pipe. The rear sensor is located in the exhaust pipe near the catalytic converter. Put on safety glasses if you crawl under the Cavalier. 2. Locate the wire harness to the oxygen sensor. Use the flathead screwdriver to press in on the clip lock of the plug on the oxygen sensor wire and separate it from the wire harness. 3. Spray a liberal amount of penetrating oil on the threads of the oxygen sensor and allow the oil to soak in. 4. Place the box end wrench or socket onto the oxygen sensor and turn it counterclockwise to unthread it from the exhaust pipe. Remove the sensor. 5. Thread the new sensor into the oxygen sensor porthole in the exhaust pipe and tighten using the wrench or socket and a ratchet. Do not overtighten. Make sure its snug, but it is easy to strip the threads on the oxygen sensor so be careful. 6. Plug the oxygen sensor wire back into the wire harness and secure the wire so it does not dangle. 7. Remove the tools and either lower the vehicle or close the hood.

      I am having a Mazda MPV Dx 2001 And its engine lights are On. Mechanic tested and says that itS Air mixing to fire the engine are not proper so O2 sensor has to be checked. Can you please let me know, the all sensor cost will be, how much and how many total sensor are there. Some says 4 on both bank and two more. is this correct.
      Asked on 9/18/2010 by Masood Khan from Hamilton On. Canada

        There are 4 of them on this car. Typically Bank 1 Sensor 1 refers to the same bank that cylinder 1 is on. Being that there is 3 o2 sensors on this vehicle,1 sensor is always before the cataletic converter. Bank 1 sensor 1 should be located to the front of the vehicle. You need to get underneath the car. Because the engine is turned sideways the first sensor on Bank 1 is near closer to the driver than the front of the vehicle. Just follow the tailpipe up to the engine. The first one goes up and it's in a tight position, but do what you can to get to it. Lot's of WD-40. The rest of them follow down the tail pipe.
