The people I am thinking about buying the car off of said they can%26#039;t get one of the oxygen sensors off to replace it. They did 1 , and there is still another. This is an 03 Sonata.
Tell me what you think. They are selling it for 1100 obo.
Is this something a mechanic at a shop should be able to do easily enough?
Thanks|||On my 1990 Geo Metro, there are 2 sensors, one on the front of the engine right on the exhaust manifold, the other down and under in back on the exhaust header where it meets the tailpipe. The back sensor requires the car to be on a lift to get to the sensor. It MAY be they were just lazy and did not swap out the back sensor. More likely, there is something else wrong and using the back sensor claiming it is too hard to reach as an excuse which covers the problem. You need to do MORE investigation here. Take the car to a mechanic, and lay out what you have been told. A reputable mechanic will TELL you of potential problems and what they MIGHT be covering up using the sensor as an excuse. The mechanic has nothing to gain or lose by telling the truth. He gets paid for his time either way, good or bad results so there is no incentive to lie unless you have told him he is getting your business in advance of his results.|||O2 sensors are usually located on the exhaust manifold. If the car is a transverse (side) mounted 6 cylinder motor, they probably changed the easy to reach front sensor. The other O2 sensor is on the back manifold and you may need to raise the car on a lift and reach it from the bottom. Changing the O2 sensors is a relatively minor repair, just difficult to reach.|||Not only should it be fairly easy for a mechanic, it%26#039;s a common repair, and they should have a set cost for it, just like an oil change or brake pad replacement. Just call your dealer, and they%26#039;ll give you a price.|||its not easy for us !
who is mechanic and trained can do easily!
