You have most likely a sensor harness wiring problem, no signal return, at this point your system needs to be hooked up to what is called a "break out box" to see what lead is dead, most likely a broken burnt or damaged wire, there is no easy way to do this, I strongly suggest this go to the Volvo dealer for diagnosis or rewire that sensor all the way back to the PCM (Powertrain Control Module), but preform these few checks 1st before you give up, pull the connector off at the sensor and look for pushed out pins in either the male or female side of the connector, you may also want to swap that sensor with the adjacent O2 sensor and see if the code comes up for bank 2 sensor 1, in that case the new sensor is defective, that is rare but it does happen.

SOURCE: Just changed my oil on a 2005 Buick Lesabre. The

Most common reset is....... turn on the key (do not start) and depress gas pedal 3 times in 5 seconds.
Remove floor mat to do this.
It should be reset.
You may have to repeat this....it does always take on the first try.

2nd common......push mileage reset until oil life shows......once showing hold button down until 100% oil life shows.

You may have one or the other.

SOURCE: how to replace 02 sensor p0141 bank 1 sensor 2?

there are only two O2 sensors on your vehicle. The one before the catalytic converter is bank 1 sensor 1 (also known as upstream). The one after the catalytic converter is Bank 1 Sensor 2 (also known as downstream).

You will need to jack up the car and safely support it in order to crawl under the vehicle to access the downstream O2 sensor. Unplug the connector and use a 7/8" wrench to remove the O2 sensor from the exhaust pipe. Install the new O2 sensor, tighten until snug, and plug in the connector.

Special socket required to remove. Disconnect the wiring harness from the sensor. Use the socket and a remove. You may need to spare with something like wd40or pb blaster other spray to help with removal.

How to change an oxygen sensor on a 2006 Buick rendezvous


The trouble code should tell you which 02 sensor? The 02 sensors are in the exhaust, sensor 1/sensor2, whatever, bank 1/bank2, whatever, before the cat, after the cat. You have several 02 sensors in the exhaust, don't know which one?
You should be able to remove/install with proper size wrench or deep socket. They do make an 02 sensor socket that has that slot in it, not sure if you need that, though.

2002 Buick Lesabre codes P0131, P0171, and P1133.


Sounds like you just need to replace the one or two 02 sensors on bank 1.If you have over 100,000 miles the 02 sensos are realy to be replaced just as spark plugs and air filteres. If you wait to long to replace them you take a chance of them not comming out and then when they do go bad you will need to replace the exhaust as well.Hope this helps and good luck.
