Where is the secondary oxygen sensor located?

Where is the secondary oxygen sensor located?

The Primary Oxygen (PHO2) sensor is placed between the catalytic converter and the exhaust system. The secondary sensor, located after the catalytic converter, is now used to monitor the first sensor to improve fuel economy and emissions control.

Where is the upper O2 sensor located?

The oxygen sensor helps keep that balance in check. The sensor is typically located on the passenger side of the car, mounted directly onto the exhaust pipe near the catalytic converter. When the sensor goes bad, your car may lose up to 40 percent of its fuel efficiency, because your car will use too much gas.

Why do I have 2 O2 sensors?

The dual oxygen sensors within an exhaust pipe can detect the cleanliness of the exhaust before it enters the catalytic converter, and then compare it to the cleanliness of the exhaust as it leaves. The sensors help ensure the optimal performance of your vehicle.

What is a secondary O2 sensor?

The secondary o2 sensor just measures oxygen after the cat to check the efficiency of the cat but otherwise it functions the same way as the primary o2 sensor.

Do you need a secondary O2 sensor?

You must have the secondary O2 sensor for the car to run correctly. That doesn’t sound too nutty if you have some E85 in the tank.

How does an oxygen sensor on a Chevy Venture work?

The computer on your Chevy Venture uses data from the oxygen sensor and other components to determine the best air/fuel ratio during engine operation at any given moment. This helps lower harmful emissions and improves engine performance.

What is the O2 sensor wiring diagram for Chevy?

09 Aveo O2 Sensor Wiring – Wiring Diagram Data – O2 Sensor Wiring Diagram Chevy The diagram provides visual representation of an electric arrangement. However, this diagram is a simplified version of this structure. It makes the procedure for building circuit easier.

Where are the oxygen sensors on a car?

You will find one on the front exhaust pipe, between the exhaust manifold and the catalytic converter. It is called the upstream oxygen sensor. The downstream sensor is just after the catalytic converter, threaded on the back pipe.
