The oxygen sensors are located on the engine exhaust manifold . The also could be one on the exhaust system past the catyllic convertor.
You need a wrench to remove the sensor and replace them by screwing them back in. The prolblem is the sensor sometimes welds on the exhaust system and almost impossible to remove with out correct equipment.
I would take to a local mechanic.
The repairs are fairly in expensive.

O2 sensors are normally on exhaust manifold or pipe lreading from. They screw in and have eire connectors. WD40 the threads beforeattempting to unscre with proper fitting wrench. the message o2 sensors does not mean they are specifically bad.It could mean they are signalling a plroblem, mainly the cat converters. of course sensors are the less expensive and should be change anyway if the catayctic converters are replaced.. Have your exhaust system and converters checked by a muffler shopbefore spending any money.

Baisically you you will have a sensor some where on the exhaust manifold and one in the cat convertor. They should unscrew with a wrench. But be aware the sensors link into the ECU which means that even if you change them yourself the codes will be stored in the memory and you will need to take the car to a garage that has a computer that can clear the fault codes before the light goes out on the dash.

There are 4 02 seneors in that motor. All are located in the exaust2 befor the cats and 2 after. Which ones did you get codes for? What codes? They are easy to change, 7/8 wrench but do it white the engine is cold or you will damage the exaust system. Good Luck

Is their a fuse for the check engine light on a 2000 olds bravada ?


Probably not.

The check engine light will come on for various things such as an O2 sensor having gone bad. It will also come on if the seal on the gas cap has gotten a leak. It will come on when the air conditioning system is too low on coolant, as well, as well as for a number of other things.

Usually, the car will need to be put on a diagnostic computer to determine exactly what the check engine light actually means.

Most local mechanics have these diagnostic computers these days, as do all of the car dealers, or a Sears Auto Center. Take you pick and have one of them run a diagnostic check on the car to find out what's actually causing the check engine light to come on.

It's highly unlikely that it's a fuse however, as all of the items I mentioned above which I've had experience with have no fuse associated with them. They just trigger the check engine light, and it takes one of those diagnostic computers to determine what the actual cause is.

On my 2000 Olds Bravada, the ABS light came on and, almost simultaneously, the transmission disengaged.


Did you get a check engine light? If so, have someone read the code(s) stored in the car's computer - that will at least lead you down the right path.

How do you know if you have a faulty rear ho2s sensor and where is it located?


o2 sensors are located on the exhaust pipes
1-2 before the cataltic converters and 1-2 after the cat. converters. 4 cyl engine has 1 before and 1 after. 6 and 8 have 2 before and after mostly) to determine if they are bad it is best left to a repair facility to run a computer diagnostic test routine and or emissions system tests.

Where is the fuel pressure regulator located at in a 94 bravada


My friend, I suggest you go by your local Auto Parts Store and purchase a Haynes Repair Manual on this vehicle. There are many sensors and electronic controls involved with this engine as I'm sure you already know. Any one of these can memic something that "it is not".
If your problem is the Pressure Regulator, it is located inside the "Tunnel Ram" intake manifold along with the multiport fuel injection system.
Now,,, before I went through the trouble and expense of going into the Intake Manifold, I would run the EMC in Diagnostic Mode and see if there are any codes present.
