If the downstream (rear) oxygen sensor wiring harness contacts the propeller (drive) shaft, it can damage the oxygen sensor and the wiring harness for the sensor, and/or cause Check Engine Light illumination. The wiring harness should be repaired and secured away from propeller shaft.

gmc pickup o2 sensor wire contacts front driveshaft
my harness wrapped around my drive shaft and pulled loose 3 other harness. i am having one heck of a time trying to figure out what goes where. if you own a xj you should make sure to check and make sure this harness is tied up in its little slot so this does not happen to you. this happened to me at night on a busy road and i never found the connectors and you cannot buy them at a parts store because nobody manufactures them anymore and the only ones i have found at the scrap yards all of the harness have already been picked apart.
