Introduction
Infiniti P1140 Code is an error code that appears on the dashboard of Infiniti cars. This code indicates that there is an issue with the engine and needs to be addressed. In this article, we will discuss the causes and solutions for this error code.
Faulty Oxygen Sensor
The Infiniti P1140 code indicates that the oxygen sensor is not working correctly. The oxygen sensor measures the amount of oxygen in the exhaust and helps the car’s computer adjust the fuel and air mixture in the engine. If the oxygen sensor is faulty, it can cause the engine to run improperly and trigger the P1140 code.
Ignition Coil Issues
Another common cause of the Infiniti P1140 code is an issue with the ignition coils. Ignition coils are responsible for providing the spark that ignites the fuel and air mixture in the engine. If the coils are not working correctly, it can cause the P1140 code to be triggered.
Leaking Exhaust Manifold Gasket
A leaking exhaust manifold gasket can also cause the Infiniti P1140 code to be triggered. An exhaust manifold gasket is responsible for sealing the exhaust system and preventing air and exhaust from leaking. If the gasket is leaking, it can cause the oxygen sensor to give inaccurate readings and trigger the P1140 code.
Conclusion
In conclusion, the Infiniti P1140 Code is an error code that indicates an issue with the engine. The most common causes of this code are faulty oxygen sensor, ignition coil issues and leaking exhaust manifold gasket. It is important to address these issues promptly to ensure that your vehicle is running correctly and efficiently. If you are experiencing the Infiniti P1140 Code, it is best to have a professional mechanic inspect your car to diagnose and repair the issue.
