In this situation, you should check the sensor grounds for these sensors, they may share a grounding point, and if it's bad both sensors could have faulty signals. You can also monitor the signals with a scan tool and see that they are within the specifications. Check the wiring real good and if all else fails, the engine control module may be defective.
