SOURCE: where are the oxygen sensors on my 2004 tahoe and installation

There are 4 o2 sensors.They are all on the exhaust system.There is one on the left side exhaust manifold pipe and one on the right exhaust manifold pipe.Then there is one in front of the catalytic converter and one in back of the converter.It would be better if you had the codes that they got because there can be other problems that can cause an o2 sensor to fail.Also I have never had all 4 sensors go bad at one time.You could have other problems.Vacuum leaks,plugged air filter,bad connections,or bad grounds.These vehicles are also good for intake gaskets being bad.Hope this helps.Good luck.

SOURCE: 2004 hyundai elantra oxygen sensor

Your Elantra has more than one oxygen sensor. There is a pre-catalyst sensor and a post-catalyst sensor. Both can be found on the exhaust. You simply disconnect the sensor wire and remove the sensor plug with the proper size deep socket. Be sure you have the correct sensor for replacement.

Because of the heat involved with the exhaust, make sure the engine is cool before attempting to remove and replace the sensors. They may be tough to remove so a shot of WD-40 or 5-56 spray may need to soak into the threads to ease removal. When you replace the new sensors, a coating of anti-seize will be helpful for future removal.

Keep in mind that one malfunctioning sensor can send information that will set off codes on other sensors "downstream" or send codes from other emission controls on the engine.

SOURCE: 2004 escalade ac problem

The AC blend door must be sticking, this is caused by the blend door motor, or in some cases a warped door that sticks, to fix this you will have to pull the dash and test the operation of the blend door which is in the AC ducting plenum chamber.

2004 cadillac escalade reverse lights and backup sensors not working what could be the problem


First check the fuses, one on left side of steering wheel - the other on the left (drivers) side under the hood. Look at the inside of the lids to see what the fuses work on. If fuses are okay, check the ground wires.

If you're wondering about the Traction light on the dash...
Make sure you have all the same tires with uniform tire wear. Large differences in tread wear could cause this.. Another cause is a wheel speed sensor that's reading incorrectly and registering one wheel at a different speed than the other speed sensors. This would require the use of a scan tool that can read ABS data, to find the problem.
