Where is the oxygen sensor located in a 1989 cadillac deville?
on the exhaust just in front of the catalytic convertor. Good luck
Could someone tell me on a 1997 Cadillac de ville where would the oxygen sensor bank 1 sensor 2 be located?
the oxygen sensor is on the exhaust system located straight down from the firewall in the middle of the engine compartment you need a special socket tool like a line wrench because you have to go around the two wires that leads into the sensor, you also need long extension to reach the area, like a foot an a half extension with your ratchet.
