Code P0135

I have a 2000 LX Civic and recently my "Check Engine" light came on. I know the code is P0135. What does that mean? Does any one know how much and what is entailed in fixing it? Do I maybe need a new sensor?

Thanks in advance for your help!

P0135 is a heater failure in the primary o2 sensor. Thats the Oxygen sensor thats closest to the engine in the exhaust manifold on your car.

Probably about 200.00 for the sensor.
