As I say, always go for factory parts because they can be more reliable, but if you can't afford them or they aren't available then getting aftermarket parts are a good idea. But they are also a good idea for a short time because they are used.
Depends on if the engraving was factory or aftermarket and how good it is. 100-1000 USD
The oxygen sensors on all vehicles are uasually located before and after the catalitic converter to monitor your emisions ! Good Luck !
not a good idea
you have three oxygen sensors, 2 on the front and rear exhaust manifolds, right past where the pipes are connected together. and one by the catlyc converter good luck paul g
The 2000 Nissan Pathfinder has a total of four oxygen sensors - two before the catalytic converter, and two after the converter. The front sensors have 3-wires, and the rear sensors have 4-wires. For a good quality OE-style sensor, they'll cost around $100 each.
There are four of them. Two of them are before the cats and two of them are right after the cats. For a nice diagram of the 02 sensors, jump on over to Smokinvette.com! Good luck!
Oxygen sensors are located at the same place on all cars cause they all do the same thing: analyze your exhaust gas. It will be on the exhaust pipe, between the engine and the catalytic converter. thats good but there are 3 of them
You should consider getting yourself a service manual. Either from your factory manufacturer or aftermarket. Both one should be good as they do teach you how to AC replacement.
The #1 oxygen sensors are installed into the exhaust manifold. If a vehicle has #2 oxygen sensors, they are after the catalytic converter. Bank 1 is between the engine and the firewall. It is highly recommended that you replace both oxygen sensors at the same time, since the failure of one sensor is a good indicator that the other is about to fail.
You can use aftermarket magazines in your handgun. Many after market magazines are as good as or better than what comes with the handgun. On the other hand, many are worse. As a general rule, factory magazines are preferred for reliablility since the factory has done extensive testing.
There really isn't any way to test the oxygen sensor to see if it is good or bad. If your check engine light is on you can take it to Autozone and they will hook it up to computer and if the oxygen sensor is bad, the computer will detect it.
