Seanmannino Posted February 9, 2010 Report Share Posted February 9, 2010 Okay, so I really hope I am not as blind as they tell me! Does anyone here have picture locations of where the four O2 Sensors are on the 97 De Ville? I have searched high and low on this car and cannot find them. I need to replace the one in Bank 1 Sensor 1 but would like to know were the others are for sure. Any help on this will be greatly appreciated. Thank you all for your time and assistance!

Ranger Posted February 9, 2010 Report Share Posted February 9, 2010 There is one on each exhaust manifold. One before the CAT and one after the CAT. Bank 1 Sensor 1 is on the right exhaust manifold by the firewall. It's the hardest one to get to. Link to comment Share on other sites More sharing options...
