Shop Jeep Liberty Replacement Oxygen Sensor

The road is rough, but your Jeep Liberty was designed to overcome it as long as it is maintained with top quality replacement parts. You invested in your high-performance car or truck to take advantage of its high-end engine power and performance, support your investment and install the best new parts. A high-performance vehicle needs the best replacement parts you can find. Found near the exhaust manifold, your vehicle's Jeep Liberty Oxygen Sensor passes oxygen levels present in the engine's exhaust system to the engine computer. Oxygen Sensors are necessary parts that are installed in the fuel system to maximize fuel performance. In cases where the air-fuel mixture is too lean, poor engine function will be the result; in addition, a too-rich mixture can lead to excessive wear to the engine and unwanted air pollution from the car or truck's tailpipe. A high quality Oxygen Sensor measures the amount of oxygen which is feeding your car's engine cylinders. The Oxygen Sensor operates in combination with the vehicle's central processing unit to decide whether the fuel vapor provided to your engine needs to be fine-tuned.

Research on Oxygen Sensor for Jeep Liberty

Sold from 2002-12, the Jeep Liberty was the successor to the Cherokee, one of America's original compact SUVs. True to its brawny Jeep lineage, the Liberty boasts extensive off-road capability, and is able to tow up to 5,000 pounds, which is a robust figure for its class. These are qualities not found in most other small utility vehicles from this era, which saw the rise of crossover SUVs being fine-tuned for the suburban lifestyle. On the down side, the Jeep Liberty has a weak engine lineup, with sluggish acceleration and poor fuel economy from both the four-cylinder and V6 engines. Interior quality and comfort are also lacking, and by today's standards, the Liberty's general lack of refinement leaves much to be desired.

The oxygen sensor measures oxygen levels in the exhaust gases that are exiting the engine. This information is used by the Powertrain Control Module (PCM) to determine the correct air to fuel ratio for your engine. The sensor is located in the exhaust system and allows the fuel injection and engine timing to work efficiently, which assists with emissions control. The oxygen sensor transmits the data to the vehicle's PCM to maintain the optimal air to fuel ratio for your engine. A bad or failing oxygen sensor will have a negative impact on environmental emissions and engine performance.

If you have a bad or failing oxygen sensor, the Check Engine light will illuminate. This light can come on for many different reasons, so it is important to have it looked at by a professional who can correctly diagnose the exact cause. A bad or failing oxygen sensor will throw off the accuracy of the fuel-delivery and fuel-combustion systems. If a bad or failing oxygen sensor disrupts the air to fuel ratio mixture, or too much fuel enters the engine, you will suffer reduced gas mileage.

As your oxygen sensor goes bad you may notice your vehicle is running rough, misfiring or running irregularly while idling. Since the oxygen sensor output helps control engine timing, combustion intervals, and the air to fuel ratio, a bad sensor can disrupt these engine functions, causing a rough or irregular engine idle.

The oxygen sensor does fail with time and age, so if your vehicle was manufactured within the past 15 years, the oxygen sensor should be replaced every 60,000 to 90,000 miles. Replacement of a bad or failing oxygen sensor will reduce the level of emissions your vehicle puts into the atmosphere, while keeping your engine running smoothly. As soon as you notice your Check Engine Light, poor gas mileage, or an irregular engine idle, you should replace your oxygen sensor to keep your engine running smoothly and efficiently.

What is the Jeep Liberty Oxygen Sensor replacement cost?

Both Denso and Bosch manufacture superior oxygen sensors for the Jeep Liberty, and there is little variance in the prices they can be purchased for at PartsGeek. The Densos run from $20 to $28, while you can get a Bosch for $24 to $38.
