Diagnostic fault codes never say to replace parts. They only indicate the circuit or system that needs further diagnosis. You could have a wiring problem to the sensor, a leak in the fresh air tube between the sensor and throttle body, or the sensor could be defective. There's a procedure for checking the wiring to eliminate that first, THEN you can suspect the sensor.
