Do you have to a tech reset check engine light or if it goes out on its own 2000 jaguar type S?

It may be necessary to perform a tech reset to turn off the check engine light in your 2000 Jaguar Type S. While some check engine lights may turn off on their own after the problem that triggered them has been resolved, this is not always the case. If the light stays on, a tech reset may be required to clear the fault code from the vehicle's computer. This can be done using a diagnostic tool or by disconnecting the battery for a short period of time. However, it is important to note that simply clearing the fault code does not necessarily fix the underlying issue, and further diagnosis may be necessary to ensure the problem is fully resolved.
