Eating O2 Sensors

[discnik]

2002 Elantra. In the last year this vehicle has had three downstream, (After Cat), O2 sensors put in it. The last sensor caused the ECM fuse to blow causing a crank but no start condition.

Has anyone else had this problem with theirs ?

Also in the wire loom going to the ECM there is oily fluid in it but cannot find the source of the intrusion.

Any ideas ???

Have you tired checking on the cat to see if its eithier stopped up or if there is a blockage somewhere along the exhaust to prevent it from breathing and thus causing to burn the O2 sensor?

What kind of O2 sensors are being used for the replacement?

i think you have a wiring problem, not the o2 sensor problem

the trouble codes that gets triggered can be either the sensor itself or the wiring
