What is an O2 sensor?

Modern cars (those manufactured in the last 40 years) contain O2 sensors. This part measures the level of oxygen in your exhaust.

How does an O2 sensor work?

To measure the amount of oxygen in the exhaust, the O2 sensor is located in the exhaust pipe. If the sensor detects too little or too much oxygen, it sends a signal to the computer in the engine so the vehicle’s system can adjust the fuel mixture appropriately. The engine’s control unit changes the amount of fuel released to reduce emissions and ensure your vehicle runs as efficiently as possible.

Why is an O2 sensor important?

If your car uses an inappropriate mixture of oxygen and gasoline, it can release harmful pollutants. It can also cause damage to or failure of your engine.

How do I know if my O2 sensor needs to be replaced?

If your vehicle experiences difficulty starting, erratic jerking or a poor idle, you may need a new O2 sensor. The check engine light may also come on if you need a new O2 sensor. Another sign of a bad O2 sensor is inefficient vehicle operation. If you notice any of these red flags, you should contact your local exhaust shop in Gary, IN for repairs.

Can I replace the O2 sensor myself?

This repair can be a DIY job, but only if you have the right knowledge and tools for proper diagnosis and replacement. To test the O2 sensor, you’ll need a digital voltmeter or an OBD2 diagnostic tool. If you discover the O2 sensor has failed, you’ll need to order the appropriate replacement.
