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 they can not be cleaned. Must be replaced.
bosch 15716 and bosch 15718 are the same exact sensor, the difference is the length of the wiring the 15718 has a longer wire. Both sensors would go before the catalytic converter. 15717 goes after.
Oxygen Sensor There are actually (4) O2 sensors on your truck. If you look inside the wheel wells behind the fender liner, right about where the frame is one O2 sensor, the other is underneath the truck about half way back in relation to the transmission. If you see where the exhaust joints together, you went about 6" too far. When you start looking at the O2 sensors, they are normally numbered something like "Bank 1 Sensor 1" Bank 1 is on the passenger side; Bank 2 is on the driver's side. Sensor 1 is the upstream sensor (near the frame, between the block and the cat) and Sensor 2 is near the Y-pipe (downstream of the cat). Normally it is the upstream sensors (sensor 1) that go first. They see the harshest conditions. You will need; Oxygen Sensor Socket Anti-Seized Penetrating Oil Sometimes it will take 15 minutes or take a few hours it depends on your luck…
This truck has a timing chain, not a belt. The chain will last longer than a belt and should not be replaced until it fails.
Front drivers side sensor on crossover exaust pipe needs replaced. Note: use a socket made for oxogon sensors. Use anti seize if it's not on the new one when installing. After your done disconect neg. terminal of battery for 30sec. This should clear the code.
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.
There are 3 oxygen sensors and all 3 should be changed for the best performance and fuel economy. ON THE 1995 Ram there is only one O2 sensor on the cat
They are replaced when they go bad.
The oxygen sensors that connect to the exhaust system. There should be two, and they should screw into the side of the exhaust.
When do you replace the timing chain on a 2005 Suzuki Grand Vitara?
Should be 4.
Oxygen bags? Are we talking air bags or oxygen sensors?
It should have 4 of them.
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
