Furthermore - when I unplugged mine to replace them, one connector was saturated pretty well with engine oil, believe it was the intake one - closest to the front bumper. I used electrical contact cleaner spray to clean it all out and let it air dry about 5 minutes before I plugged it back into the new sensor.

Yours might be wet w/ oil and not making good connection or giving faulty reading.

Good luck!
