SOURCE: change oxygen sensor

Under hood, center, front engine area, above exhaust pipe flange, mounted in exhaust manifold
Application:
Front
Under hood, center, rear engine area, above exhaust pipe flange, mounted in exhaust manifold
Application:
Rear

The oxygen sensor may be difficult to remove when the engine temperature is below 120°F (48°C). Excessive force may damage the threads in the exhaust manifold of exhaust pipe.

  1. Start the engine and let it warm up to 120°F (48°C), stop the engine and disconnect the negative battery cable.
  2. Detach the electrical connector from the oxygen sensor.
  3. Using a special, oxygen sensor socket, remove the oxygen sensor from the exhaust manifold or exhaust pipe.


NOTE A special anti-seize compound is used on the oxygen sensor threads. The compound consists of liquid graphite and glass beads. The graphite will burn away, but the glass beads will remain, making the sensor easier to remove. New or service sensors will already have the compound applied to the threads. If an oxygen sensor is removed from the engine and if for any reason, it is to be reinstalled, the threads must have this anti-seize compound applied before installation.
  1. Coat the threads of the oxygen sensor with anti-seize compound 5613695 or equivalent.
  2. Install the sensor and tighten it to 30 ft. lbs. (40 Nm).
  3. Reattach the electrical connector to the sensor and the negative battery cable.

SOURCE: can only find oxygen sensor on rear exhaust fork

Normally you'll find at least one before the catalytic converter & after. You'll have to look real close at manifolds as they route from cylinder head then down , and then follow exhaust pipes to & after catalytic converter.

its simple to do. just unplug the sensor and unscrew it. if its frozen and hard to break loose, then just heat the base the part of exhaust that it goes into.

SOURCE: remove oxygen sensor

There is no special tool needed, try spraying WD-40 on it to loosen it up, or try using a Breaker Bar or Pipe on the wrench for more leverage. It has received alot of heat there in its lifetime and could be very tight and could have welded itself to the bung. When you reinstall a new one put some Anti-Seize Compound on it so you won't have that problem next time.

My 2000 Cadillac Deville engine light on. Engine code PO420


Catalyst System Efficiency Below Threshold (Bank 1)

A code PO420 may mean that one or more of the following has happened:
  • Leaded fuel was used where unleaded was called for
  • An oxygen sensor is not reading (functioning) properly
  • The engine coolant temperature sensor is not working properly
  • Damaged or leaking exhaust manifold / catalytic converter / exhaust pipe
  • Retarded spark timing
  • The oxygen sensors in front and behind the converter are reporting too similar of reading

  • Check for exhaust leaks at the manifold, pipes, catalytic converter. Repair as required.
  • Use a scope to diagnose the oxygen sensor operation (Tip: The oxygen sensor in front of the catalytic converter normally has a fluctuating waveform. The waveform of the sensor behind the converter should be more steady).
  • Inspect the downstream heated oxygen sensor (HO2), replace if necessary
  • Replace the catalytic converter

How do I change the oxygen sensor


Locate the faulty oxygen sensor in the exhaust system, disconnect the electrical connection, and then you will either need the correct size box wrench or oxygen sensor socket(available at most part stores) to remove the sensor. I recommend either warming up the exhaust system a bit and being careful not to get burned or using liquid wrench to help loosen it up. Installation is the reverse. Just make sure you remove the correct sensor, these new vehicles often use more than one oxygen sensor.(bank1 is driver's side, bank2 is passenger's side, sensor1 is before the catalytic converter, and sensor2 is after the catalytic converter)

'97 Grand Marquis needs a new Oxygen Sensor


this is going to be on the left side of the exhaust second sensor back or if you only have two sensors it will be just after the cat. all you need is a 7/8 wrench. to change it unless you have the o2 sensor socket.

REPLACING OXYGEN SENSORS


    Remove the Oxygen Sensor
  1. Step 1 Start the engine and let it idle for four minutes to raise the exhaust system temperature. This will make removal of the oxygen sensor much easier and prevent damage to threads on the exhaust pipe.
  2. Step 2 Turn off the engine.
  3. Step 3 Detach the ground battery cable using a wrench.
  4. Step 4 Locate the oxygen sensor or sensors you need to replace. The sensors are threaded into the exhaust pipes before and after the catalytic converter. The oxygen sensor has a cylindrical body and the approximate size of a spark plugmag-glass_10x10.gif.
  5. Step 5 Raise the front of your vehicle using a floor jack and support it on two jack stands. This will help you gain access to the sensor or sensors if necessary. If you need to work under the vehicle, wear safety goggles.
  6. Step 6 Unplug the sensor electrical connector.
  7. Step 7 Unscrew the oxygen sensor using a box-end wrench or a ratchet and oxygen sensor socket.
  8. Step 8 Remove the sensor or sensors from the vehicle.
  9. Install the New Oxygen Sensor
  10. Step 1 Apply a light coat of electrically conductive anti-seize compound to the threads of the new oxygen sensor.
  11. Step 2 Thread the oxygen sensor into the exhaust pipe by hand first.
  12. Step 3 Finish tightening the sensor using the box-end wrench or ratchet and oxygen sensor socket.
  13. Step 4 Plug the sensor electrical connector.
  14. Step 5 Lower the vehicle.
  15. Step 6 Attach the ground, battery cable using the wren

How do you change the oxygen sensor


Follow the thin, stiff, wire to the oxygen sensor down the exhaust manifold, to the pipe where it is installed. It is just screwed in and comes out with the right size socket or wrench. Liquid Wrench or WD40 helps loosen it. But don't get anything on the new one. If you put antiseize on the threads, stop short, so that you don't get any on the sensor portion.
