What Is The Difference Between The Service Engine Soon And Check Engine Nissan? (2023)

The Service Engine Soon and Check Engine Nissan lights in a vehicle serve as warning systems to alert the driver to potential issues with the vehicle’s engine or emissions control system. The “Service Engine Soon” light is a less severe warning than the “Check Engine” light and typically indicates a minor issue that does not require immediate attention.

For example, the “Service Engine Soon” light may come on if the vehicle’s computer detects a minor issue with the emissions control system, such as a loose gas cap or a failing oxygen sensor. In these cases, the issue can often be resolved by tightening the gas cap or having the oxygen sensor replaced.

On the other hand, the “Check Engine” light is a more serious warning and indicates a potentially significant issue with the engine or emissions control system. The “Check Engine” light may come on if the vehicle’s computer detects a problem with the catalytic converter, engine misfire, or other major component of the engine or emissions control system. In these cases, it is important to have the vehicle inspected by a qualified Nissan mechanic as soon as possible to determine the cause of the light and what repairs are necessary.

What Should I Do If My Nissan “Service Engine Soon” Light Comes On?

If the “Service Engine Soon” light comes on in your Nissan vehicle, it is important to have the vehicle inspected by a qualified Nissan mechanic as soon as possible. The mechanic will be able to connect a diagnostic tool to the vehicle’s computer to determine the cause of the light and what repairs are necessary.

In some cases, the issue causing the “Service Engine Soon” light to come on may be minor and can be resolved by tightening the gas cap or replacing a faulty component. In other cases, the issue may be more significant and may require more extensive repairs.

It is important to address any issues causing the “Service Engine Soon” light to come on promptly to prevent further damage to the engine or emissions control system, as well as to ensure the safety and reliability of your Nissan vehicle.

In some cases, the issue causing the check engine light to come on may be a simple fix, such as tightening the gas cap or replacing a faulty component. In other cases, the issue may be more significant and may require more extensive repairs.
