What Are The Common Reasons For The Nissan Check Engine Light Symbol To Come On? (2023)

The Nissan check engine light symbol can come on for a variety of reasons. Some common causes include a faulty oxygen sensor, a loose gas cap, a malfunctioning catalytic converter, a damaged or worn spark plug, or a failing ignition coil. Other potential causes include a clogged air filter, a malfunctioning mass airflow sensor, or a problem with the vehicle’s electronic control module (ECM).

It is important to note that the check engine light is not always an indicator of a serious problem. In some cases, it may simply be a minor issue that can be easily fixed. However, it is always best to have the problem diagnosed and repaired as soon as possible to prevent further damage to the engine and emissions system.

Can Driving With The Nissan Check Engine Light Symbol On Cause Damage To The Car?

Driving with the Nissan check engine light symbol on can potentially cause damage to the car, especially if the issue is related to the engine or emissions system. The check engine light is an important indicator that there is a problem with the vehicle’s onboard computer or emissions system, and it should not be ignored.

When the Nissan check engine light symbol comes on, it means that the vehicle’s onboard computer has detected a problem with one of the many sensors or systems that it monitors. If the problem is left unchecked, it could potentially cause further damage to the engine or emissions system, leading to costly repairs down the line.

For example, if the check engine light is caused by a faulty oxygen sensor, it could lead to decreased fuel efficiency and increased emissions. This could eventually cause damage to the catalytic converter or other emissions components, resulting in expensive repairs.

In some cases, driving with the check engine light on could also cause additional problems, such as decreased engine performance or increased fuel consumption. This could result in decreased acceleration or difficulty starting the engine, among other issues.

Therefore, it is always best to have the problem diagnosed and repaired as soon as possible to avoid potential damage to the car. If the check engine light comes on while driving, it is recommended to pull over and turn off the engine, then consult the vehicle’s manual or a qualified mechanic to determine the cause of the problem.

How Can A Nissan Owner Reset The Nissan Check Engine Light Symbol?

Resetting the Nissan check engine light symbol can be done using a diagnostic scanner or by disconnecting the car’s battery. However, it is important to note that resetting the check engine light without addressing the underlying issue will not fix the problem.

To reset the check engine light using a diagnostic scanner, connect the scanner to the vehicle’s onboard computer and follow the instructions provided by the scanner. This process typically involves clearing the fault codes stored in the computer, which will turn off the check engine light.

To reset the check engine light by disconnecting the battery, first, turn off the vehicle’s engine and make sure all electrical components are turned off. Then, locate the battery in the engine bay or trunk and disconnect the negative (black) cable. Wait for at least 15 minutes, then reconnect the cable and start the engine. This should reset the Nissan check engine light.

However, it is important to note that disconnecting the battery can also reset other settings and systems in the car, such as the radio and climate control. If you choose to reset the check engine light by disconnecting the battery, be aware that you may need to reset these systems as well.
