Engine Mechanical problem
2003 Volvo S60 Front Wheel Drive Automatic 128K miles

My check engine light came on, and the code was a P0037. This relates to the O2 Sensor before the catalytic convertor. I replaced the sensor with a universal model and then erased the error code. The check engine light went out, but every time I start the car, the light comes on again. What do I need to do to get rid of the code?>

Do you still get the same trouble? Also is the code for signal too high, signal too low, or signal missing?
