The onboard computer of your car, truck, or SUV performs many tasks. The Jaguar oxygen sensor is part of your system, and it has an important job to do. Located near the exhaust manifold, the Jaguar oxygen sensor monitors the oxygen level of your exhaust and sends the data it collects to the electronic control unit (ECU). Your Jaguar oxygen sensor strives to meet the optimal oxygen-to-fuel ratio of 14.7:1. The data sent by the Jaguar oxygen sensor is used to determine the amount of fuel that is injected into the combustion chambers. When your Jaguar oxygen sensor is not working properly, your vehicle uses more fuel than necessary for optimal operation. This means that the Jaguar oxygen sensor is essential for fuel efficiency. Additionally, the "rich" fuel mixture that results from too much fuel and not enough oxygen can damage your catalytic converter. With the high price of gas and the cost of replacing your catalytic converter, it is in your best interest to ensure that your Jaguar oxygen sensor is working properly. There are generally no warning signs that your Jaguar oxygen sensor is faulty other than decreased fuel efficiency and eventual catalytic converter failure. Most Jaguar oxygen sensors should be replaced every 100,000 miles. You may also choose to replace your Jaguar oxygen sensors whenever you work on your fuel system.
