in the exhaust pipes that go to the catalytic converter is where the 2 sensors are you need to replace, note these are the sensors just off the engione, not after the catalytic converters, you will need to get under the car to replace them, u will need to buy a special O2 sensor socket to remove them, if they seem to come out hard spray the base with WD 40. the socket is avil from any good auto parts store, about $12 USA

2004 Volvo with under 60,000 miles may still be under emissions warranty. If the car is under 60K and less than 5 years old check with dealer to see if it is covered under emissions warranty. Depends on mileage and in service date.

Thank you for replying so quickly.
I was told there was only two on this model.
The check engine light came on and Advanced Auto hooked up a device under the dash and said the code was "P0133" for the front 02 Sensor.
I called the dealer and their service department said I should replace both.
