I have a 1996 cadillac deville concours, an it has 4 oxygen sensors
Three
On a Cadillac DeVille, the oxygen sensors are typically located in the exhaust system. There are usually two sensors: one before the catalytic converter (upstream sensor) and one after it (downstream sensor). The exact placement may vary slightly depending on the model year, but they are generally mounted on the exhaust pipes or manifold. Accessing them may require lifting the vehicle for better visibility and reach.
Should be two front and rear of engine
Do 1978 Deville come with a oxygen sensor?
The oxygen sensors are located in the exhaust pipes.
The oxygen sensor in a 1988 Cadillac Deville is located in the exhaust manifold. It constantly monitors oxygen levels in the exhaust to allow the engine to operate and peek efficiency.
In a 2000 Cadillac DeVille DTS, the oxygen sensors are located in two main positions: one upstream (pre-catalytic converter) and one downstream (post-catalytic converter) for each bank of the engine. The upstream sensors are typically located near the exhaust manifold, while the downstream sensors are positioned after the catalytic converter in the exhaust system. Accessing them may require lifting the vehicle or removing certain components for better visibility.
The 2000 Cadillac DeVille typically has four oxygen (O2) sensors. There are two upstream (pre-catalytic converter) sensors and two downstream (post-catalytic converter) sensors for each of the vehicle's two catalytic converters. These sensors help monitor the exhaust gases to ensure optimal engine performance and emissions control.
on the exhaust just in front of the catalytic convertor. Good luck
one
ur cadillac has two oxigen sensors one is behind the fans of the radiador under the car its located in the manifold the other one its on the pasenger side under the car its bolted on the cadilaconberter
