Nissan Check Engine Light: Causes, Solutions, And Troubleshooting
It can be troubling to see your Nissan check engine light glowing on the dashboard, but is it always a cause for concern? There are many reasons why this symbol might pop up. Luckily for you, Don Williamson Nissan, your local dealership and service center in Jacksonville, NC, has put together this helpful guide to potential Nissan check engine light causes and tried-and-true solutions.
Common Reasons for an Activated Nissan Check Engine Light
If you've noticed that dreaded light on your dash, you've probably landed here after searching the web for "Why is my Nissan check engine light on?" Also known as a Nissan malfunction indicator light, the check engine light can point to several issues. Here are some reasons why your light might be on:
- Low on Engine Oil: Insufficient lubrication is one of the leading causes of engine failure and other critical issues. If the hundreds of moving parts inside your powertrain have old, sludgy oil running through them, they are more likely to experience friction and cause premature wear and tear. Consider booking an inspection and oil change if you are due for this service.
- Loose Gas Cap: A loose or damaged gas cap could be the reason for an activated check engine light. Although it may seem like a minor problem, a loose or broken cap could allow harmful fuel vapors to enter your car's inner systems, not to mention the environment. This should be one of the first things you check for, and thankfully, it's an easy fix.
- Catalytic Converter Issue: If you notice the check engine light and your powertrain is acting up, it could be a sign that your catalytic converter needs attention. Additional omens include an unusual odor or a rattling and bumping sound coming from under the hood. This is a pressing and potentially hazardous issue that should never be overlooked.
- Problem With Oxygen Sensor: The proper ratio of oxygen and fuel must be maintained in order for your internal combustion engine to function well. If the system detects low oxygen, or if the sensor itself is malfunctioning, it can trigger the check engine light. We strongly suggest bringing your model into a service center if you hear a knocking sound combined with reduced fuel efficiency.
- Fuel System Trouble: Your fuel delivery system does just what it sounds like: bring fuel to the engine when it is needed. Trouble with the fuel system may result in poor performance and efficiency, or you could experience a stalled engine while trying to start your car. Since the fuel system is intricate, it can be difficult to determine exactly what's causing the check engine light to go on. Bring your vehicle to our service center to get help from an expert.
What Should You Do When the Nissan Check Engine Light Comes On?
Assess the Urgency
If the Nissan check engine light shows up as yellow and is not blinking, this likely means that the issue is not a cause for immediate concern, but you should still schedule an appointment as soon as possible to be safe. If the light is blinking or in red, the problem is urgent and potentially dangerous. Seek help from an auto professional immediately.
Inspect Your Vehicle
The check engine light is your car's way of letting you know that something is amiss. Park your vehicle in a secure area and do a quick inspection to see if you notice any obvious problems. In particular, check under the hood and make sure your gas cap is intact and fully tightened. If you can't tell what's going on, have a technician take a closer look.
Diagnose Your Nissan Check Engine Light With an OBD-II Scanner
An OBD-II scanner is a device that connects to a small port under your dashboard. Once it's plugged in, it can interpret and translate the Nissan check engine light codes into language you can easily understand. Many service technicians will also use this professional tool when you bring your model in for a diagnosis. An OBD-II scanner is great to have on hand for Nissan check engine light troubleshooting.
Consult a Professional
These Nissan check engine light solutions are helpful in the short term but might cost you more in the long run. Dashboard symbols exist to let you know when something has gone wrong, usually in a place you can't access without automotive expertise. A trained technician is fluent in your car's language and can give it exactly the kind of care it needs to thrive.
