If you own a modern car and your check engine light comes on or your vehicle isn’t running right, pray the problem is with the Nissan Teana oxygen sensor. A faulty oxygen sensor is one of the common reasons why your check engine light will come on.
Let’s face it: the check engine light is perhaps the most dreaded dashboard light for any car owner. Fortunately, replacing your oxygen sensor is a reasonably cheap ordeal compared to diagnosing and repairing an entire engine. While repairing and servicing your oxygen sensor is cheap and easy, ignoring the problem could lead to costly repairs.
What is a Nissan Teana Oxygen Sensor?
The oxygen sensor is usually located inside your exhaust pipe system. It gathers information on the percentage of oxygen in your exhaust. When there is too little oxygen, the sensor signals the ECU (Engine Control Module) that the mixture is too rich. When there is too much oxygen, it signals the ECU that the mixture is too lean.
When the ECU gets this information, it will make proper fuel injectors, timing, and engine operation. This ensures that the air and fuel mixture in the combustion chamber is at its best.
Signs your Nissan Teana Oxygen Sensor is Failing
When your Nissan Teana oxygen sensor starts failing, the vehicle ECU will not receive information about the exhaust gases. In effect, it won’t be able to adjust engine components for optimum performance. Fortunately for you, we have outlined some of the common symptoms.
- Check Engine light comes on
When your oxygen sensor fails, the first line of action is an illuminating check engine light. Depending on your vehicle’s make and model, the check engine light is a bright orange “Check Engine” light on your dashboard.
It’s important to note that the check engine light could also indicate another problem with your vehicle that needs to be assessed.
- Poor fuel economy
When your Nissan Teana oxygen sensor begins to fail, your fuel combustion and fuel delivery systems will be immediately thrown off. If your oxygen sensor affects the air-to-fuel ratio and too much fuel is pumped into the engine, your fuel economy will be negatively affected.
Therefore, if you notice that you are filling up your fuel more often, you might need to check on the health of your oxygen sensor.
- Engine runs rough
Modern cars are designed to run smoothly and silently. If your vehicle has a faulty Nissan Teana oxygen sensor, your engine will likely run irregularly and sound rough when it is idling. When your oxygen sensor fails, it impacts the engine’s timing, essential functions, and combustion intervals. The car might stall or experience slow acceleration.
- Poor engine performance
When the engine’s combustion process is interfered with, your car will perform poorly. This will also happen if you have a faulty oxygen sensor.
The driver will notice this change when driving down the road. Pressing on the gas pedal will limit the vehicle’s acceleration.
Replacing your Nissan Teana Oxygen Sensor
If your Nissan Teana was manufactured in the last 15 years, it probably has an oxygen sensor. This component must be replaced every 100,000 km to avoid experiencing the above problems.
It is also important to note that replacing your oxygen sensor will help reduce your vehicle emissions, which is a plus for the environment.
