The Jeep oxygen sensor is part of the network of data-gathering devices in the vehicle that prevents poor engine performance. Typically mounted on the outskirts of the vehicle's combustion chambers, the Jeep oxygen sensor screens the fumes on their way out to the car exhaust assembly and feeds the oxygen content read of the gas to the on board electronic control unit (ECU). A low oxygen count in the exhaust can mean a rich fuel delivery, an imbalance characterized by a decrease in power. And, because more air are not being used in combustion and simply go out to the exhaust system untapped, the air-to-fuel imbalance results in an uneconomical use of the fuel and often leads to more exhausts and wasted fuel. Depending on the oxygen content read of the Jeep oxygen sensor, the ECU makes the necessary adjustments on the fuel injection and air intake systems of the vehicle. By calculating the exhaust hundreds of times per minute, the Jeep ECU is able to make adjustments, maintain optimum engine performance and lower smoke emissions. This functionality of the Jeep oxygen sensor is especially useful in the trails, when driving under diverse weather conditions and different drive applications. Air intake is fickle, and depends on numerous factors like altitude, engine temperature, air temperature, engine load, barometric pressure, etc. The level of oxygen in the exhaust is a determinant of the quality of the burn material itself. This is critical as a poor burn not only wastes fuel but may also affect the performance of the Jeep. There are many types of Jeep oxygen sensors currently available, with the single wire oxygen sensor and the heated oxygen sensor being the most commonly used because of their durable finishes. The heated Jeep oxygen sensor has a built-in heating ingredient specifically-designed to maintain the vehicle's ideal engine operating temperature. The sensing element of these Jeep oxygen sensor types are enclosed in a heavy-duty billet to ensure their precision reads. Common factors that affect the reliability of the Jeep oxygen sensors are bad electrical connections, poor air supply, improper operating temperature, and the exposure of the sensing element to unleaded gasoline.
