Where are my 02 sensors located?
Location of the Oxygen sensor These sensors are always located in the exhaust gas flow of your vehicle. Most cars have one O2 sensor located close to the engine, typically in the exhaust manifold. Some cars have two O2 sensors or more, and the second Oxygen sensor is typically installed behind the catalytic converter.

What is oxygen sensor golf?
Your Golf’s oxygen sensors are responsible for helping to keep your engine running at optimal efficiency. The engine management computer uses the data from all of the O2 sensors to keep the air/fuel mixture optimized. A bad oxygen sensor can affect the mixture greatly. Without being able to optimize the air fuel ratio, ...
What is the first O2 sensor?
Sensor 1- Sensor 1 would be the first O2 sensor in the line of sensors starting with the exhaust manifold and making its way back to the exhaust pipe. An Oxygen sensor that is between the catalytic converter and the engine is known as an “upstream” sensor.
What is the oxygen sensor after the catalytic converter?
Oxygen sensors after the catalytic converter are “downstream sensors”. As a rule, the upstream sensor is more important for engine timing and air/fuel ratios. By using a OBDII scanner you can determine exactly which sensor is bad, and what is wrong with it.
What happens when an O2 sensor goes bad?
When an O2 (oxygen) sensor go bad, it’ll cause your Volkswagen Golf ‘s engine to run less efficiently.
How do you know if your oxygen sensor is bad?
One of the most common symptoms that an oxygen sensor has gone bad is exhaust that does not smell good. The smell is often described as “rotten eggs” or sulfuric. Either way, like with rotten food, “the nose knows”.
Does the oxygen sensor on a golf club come on?
Oxygen sensors can change the way that your Golf’s engine runs. Most of the time, the check engine light will come on. It’s a good thing that the check engine light would come on, as there is more than one oxygen sensor, and they can be difficult to get to and test.
Can a golf fail an emissions test?
Failed Emissions. Often enough, there won’t be any noticeable signs of a bad oxygen sensor. You’ll go to get an emissions check done, and your Golf fails the test. Without a check engine light, it can be tough to lock down exactly what would cause the vehicle to fail, but oxygen sensors are one of the more common causes.
How much wire does a Ford sensor have?
The Ford sensor #15718 only has about 15-16" of wire. You're going to need around 30", so don't get too eager and cut off your VW harness just yet, lthough you can cut off the plug of your new Ford sensor as close as you can towards the connection.
When did the Jetta start using wideband sensors?
At some point between 1995 and 2002 (I'm looking it up), Jetta began using wideband sensors. If you have one, begin your research by calling your VW dealership and see how much they would charge for a front sensor; some old ones may be on clearance. Tools you will need to replace an O2 sensor in VW 2.0L engines.
Where is the oxygen sensor located on a GTI?
The oxygen sensors are located in the exhaust system of the engine, and they sense the oxygen content of the exhaust gases. There are two on the GTI MkIV: one on each side of the catalytic converter. The sensor located just in front of the catalytic converter measures the mixture of the exhaust gas exiting the engine.
What is an oxygen sensor?
The oxygen sensors (also called O2 sensors) are one of the most important elements of the modern fuel injection systems. A finely tuned fuel injection system with an oxygen sensor can maintain an air/fuel ratio within a close tolerance of .02 percent. Keeping the engine at the stoichiometric ratio ...
