Jeep Genuine Mopar Oxygen Sensors

Refine Results

Oxygen sensors measure the proportional amount of oxygen in a liquid or gas. These sensors help in maintaining the optimal performance of your engine while also regulating the emission levels of the vehicle. JeepsAreUs offers a quality selection of genuine and high-quality Mopar oxygen sensors for select Jeep models and model years.

Keep your Emission Levels in Check Using Oxygen Sensors

Oxygen sensors or lambda sensors are electronic devices that measure the oxygen levels in liquid or gas. These sensors are mounted in the exhaust manifold so that it can easily monitor the amount of unburned oxygen in the exhaust as it exits the engine. The sensors then send data to a computer and analyze if the fuel mixture of the engine is burning rich or lean. Monitoring oxygen levels aid in identifying whether or not the fuel mixture after combustion is at optimal levels.

Since oxygen sensors are crucial in keeping your engine performing at its best, they must be immediately replaced once they start to malfunction. While faulty O2 sensors would set a fault code indicated by the Service Engine Lamp, some continue to function despite degradation but fail to maintain the emission levels and fuel consumption of the vehicle. Shop for Mopar O2 sensors at JeepsAreUs now and keep the engine of your Jeep in top condition.

Frequently Asked Questions:Oxygen Sensors

How many oxygen sensors does a car have?

Modern cars come with at least four O2 sensors within key points in their exhaust systems. They mostly have a sensor in front of their catalytic converters and a set of sensors in their exhaust manifolds. The number of sensors in vehicles also depends on how many exhaust pipes the car has.

How do oxygen sensors work?

These sensors create electrical power at around 600°F, the highest temperature they can reach. Lambda sensors have a zirconium ceramic bulb at the tip that goes into your exhaust manifold. The bulb gets power from varying oxygen levels between it and the outside atmosphere once it comes in contact with hot exhaust gases.

How long do oxygen sensors last?

Older or worn-out O2 sensors can last between 30,000 to 50,000 miles or 3 to 5 years, depending on your car. Newer oxygen sensors with updated heated elements can last for up to 100,000 miles or 7 to 10 years.

What causes oxygen sensors to fail?

Your vehicle could have a failing lambda sensor if it exhibits the following symptoms:

  • Your Check Engine Light is on.

  • Reduced fuel efficiency

  • The smell of sulfur and black smoke from the exhaust

  • Higher emission levels

  • stalling, skipping or bucking engine

  • Malfunctioning catalytic converter

It’s best to have your oxygen sensors replaced so your car can keep running at its best.

How do I test an oxygen sensor?

Get a digital voltmeter and set it to the millivolt DC scale. Then, start your vehicle and wait until it reaches its optimal operating temperature. Switch your engine off after that and connect your voltmeter to your oxygen sensor. Start your car again and check your voltmeter readings if they reach anywhere from 100 to 900mV.
