Hi Irish,

The mechanic just replaced the fuel-air sensor in my car and scanned the computer. It threw out another sensor failure. Call to Nissan dealership revealed that if the computer in the car is kaput, it will keep killing the sensors one by one.

Sentra computers have a 80k miles & or 8 year (whichever is earlier) warranty. So please check your car computer and change it if it is still under warranty.
