Where are the O2 sensors on a Mustang?
O2 sensors located after the catalytic converter are referred to as downstream sensors. If the oxygen sensors measure that there is too much fuel being added, called a rich condition, it will tell the ECU (via a certain electrical voltage) to cut back on fuel.
Where is the oxygen sensor in the engine?
An Oxygen sensor that is between the catalytic converter and the engine is known as an “upstream” sensor. 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.
Where are the oxygen sensors on an Audi A3?
There are many oxygen sensor related codes. These codes correspond with what side of the engine they are on (known as the “bank” for cylinder bank) and how far down stream they are. For instance, an oxygen sensor at bank 1 – sensor 1 would be: Bank 1- Side of the engine with the first cylinder in the firing order.
Where are the O2 sensors on a Volkswagen Golf?
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. Oxygen sensors after the catalytic converter are “downstream sensors”.

Where are the oxygen sensors on a Ford 3.0L?
Your 3.0L, 3.8L Ford vehicle comes equipped with several oxygen sensors, this article concentrates on testing the ones that are located before the catalytic converter ( O2S11 and O2S21 ). Contents of this tutorial: Important Suggestions And Tips. Oxygen Sensor Basics.
