Yes, one up and one downstream.
No. Upstream and downstream O2 sensors are different for a 2000, 1500, Chevrolet Suburban with the 5.3 engine.
The upstream sensor is screwed into the rear exhaust manifold. The downstream is screwed into the catalytic converter.The upstream sensor is screwed into the rear exhaust manifold. The downstream is screwed into the catalytic converter.
the upstream o2 sensor is mounted in the exhaust before the catalytic converter and the downstream sensor is after the cat. conver.
The upstream O2 sensor is mounted in the ehxaust manifold The downstream O2 sensor is mounted in the exhaust pipe after the catalytic converter
The Ford Focus Wagon has two. One before the catalytic converter (called the upstream) and one after (downstream) Most cars have 2 or more oxygen sensors. Most cars have 2 or more oxygen sensors.
both. upstream is under the hood, and the downstream is by the catalytic converter.
( 4 ) 2 that are used for air / fuel ratio upstream of the catalytic converter and 2 that are catalyst monitors that are installed downstream of the catalytic converter
It is located on the muffler by the moter and looks like a sparkplug with wire attached at the end. To be specific, my 2000 Durango has 1 upstream oxygen sensor and 1 downstream oxygen sensor. Both are located on the exhaust pipe. The upstream is between the engine and catalytic converter. The downstream is located between the catalytic converter and muffler. - Mick
It should be equipped with both.
Sensor 1 would be UPSTREAM before the exhaust enters the catalytic converter
The upstream sensor is located on the exhaust manifold, front of the engine easily accessible from the top. The downstream sensor is after the catalytic converter, on the exhaust, underneath the car. The connector is next to the oil filter.
There are two oxygen sensors. One upstream and one downstream. The up stream is located at the front of the vehicle below the radiator and the other is near the cadillac converter. If u go to o reilleys they have a tool just for removing the sensors otherwise u could use a plyers or a cressent wrench to remove them
