Your Jaguar is a British luxury vehicle that requires proper care and maintenance to keep it operating at its optimal performance. The ASE Certified Technicians at Kneble’s Auto Service Center have the skills to run diagnostic tests and make repairs on your Jaguar.
The performance and comfort of your Jaguar are managed by a network of electronic control units (ECU’s) which are essentially computers that monitor and maintain every facet of your vehicle’s performance including fuel & ignition systems, emission controls, anti-lock brakes, airbags, navigation, transmission operation, entertainment system, and much more.
The ECU’s utilize an array of sensors to monitor the health of the various systems that they control. If a system provides feedback through a sensor indicating a malfunction, you will often see a check engine light illuminate on your dashboard to let you know that there is a problem. In the best case, when the check engine light comes on, a diagnostic trouble code (DTC) is also stored in the computer (ECU) which can later be analyzed by one of our technicians to help pinpoint the system that is malfunctioning.
There are a few common issues that might cause a check engine light to come on in your Jaguar.
Loose Gas Cap – This can allow harmful emissions to be released into the environment which is why this can cause your check engine light to come on as a warning.
Overdue for a Tune-Up – As your spark plugs (and spark plug wires) wear out, your car’s performance will deteriorate. The further the vehicle’s performance gets from optimal, the more out of range your oxygen sensor readings will be, causing your check engine light to eventually come on.
Faulty Sensor – There are several sensors that can fail, causing the check engine light to come on. Most commonly seen are failures in the oxygen (O2) sensor and the Mass Air Flow (MAF) sensor.
Catalytic Converter Failure – After many years of usage, your catalytic converter can become clogged. As this happens your car’s performance can decline and your emission readings will be out of specification, causing your check engine light to come on.
This list is provided to give you some insights into common issues that could cause your check engine light to come on. Whenever a check engine light comes on, we recommend that you have a diagnostic test performed by a qualified technician to determine the root cause of the problem.
