NO. there 2 different things / sensors.
As far as I know they can not be cleaned. Must be replaced.
If the oxygen sensors for the 1991 Chevy 4.3 is running rich when it is warmed up it is best to have the sensors replaced. Once the sensors are replaced this should resolve the issue.
They are replaced when they go bad.
If you have a 2.3 or a 2.6 motor, there should just be one oxygen sensor. It will be located on the exhaust manifold. On the driver's side of the motor you should see it down by the firewall. It will have a single wire coming from it.
The oxygen sensors that connect to the exhaust system. There should be two, and they should screw into the side of the exhaust.
Oxygen sensors are located in the exhaust manifolds & in front pipes, should have 4
Should be 4.
Oxygen bags? Are we talking air bags or oxygen sensors?
Follow the exhaust back, in the exhaust there should be spark plug looking sensors with a smaller single wire coming out the top, these are your oxygen sensors. Depending on year there can be one to four sensors on your auto.
Should be two front and rear of engine
It should have 4 of them.
most o2 sensors are on the tailpipe between the engine block and the catylitic converter. if you have 2 exahst manifolds, then you should have 2 sensors
A faulty EGR valve can cause a 98 Chevy to fail a smog test. The oxygen sensors should also be tested as they can also cause a 98 Chevy to fail a smog test.
mine is not a sr5, which should be the same, has 1
It all depends on the size of the engine, but there should only be one.
The fuel additive container should say "O2 sensor safe".
If your XL-7 is a V6, then it may very well have two o2 sensors, in the event that it does it will always be worht it to replace both of these, that way it makes for less headaches down the road.
As far as I know there is 2 02 sensors if you look into the wheel well with the tires turned you can see them just to the back of the manifolds. They should be pointing straight up. I just replaced the o2 sensors in my 98 and there was 2. It may depend on if you have standard or CA/MA emissions. My truck has one with standard emissions. The same truck in CA or MA has two. 95 f150 5.8
There should be two Oxygen sensors; the one that wears out most frequently is installed in the exhaust manifold, close to where the exhaust pipe connects. The second Oxygen sensor should be behind the catalytic converter.
there should be one on the exhaust manifold and there should be another one after the catylitic convertor on the exhaust pipe
There should be one in the header and one more in the catalytic converter.
there should be 4 two are pre cat and two are post cat
should be right above the catalytic converter, on the exhaust manifold
there should be 3/1 on the left header then 2 going back
