The two codes indicate issues with both front O2 sensors. Once O2 sensors are contaminated they can continue to throw these codes even if the original cause of the contamination has been remedied. The problem can also be with the wires and/or connectors in the O2 sensor circuit, but with both codes present the primary suspect becomes the connection of that wiring harness at the PCM.
