Signs of a Bad Oxygen Sensor and How to Fix It
At MyMechanic Malaysia, we understand the importance of keeping your vehicle running smoothly. One often-overlooked component is the oxygen sensor. If it malfunctions, it can lead to various issues that impact your vehicle’s performance and fuel efficiency.
Symptoms of a Failing Oxygen Sensor
- Check Engine Light Turns On: Your car’s onboard computer constantly monitors the oxygen sensors. If it detects a problem with a sensor or its circuit, it will illuminate the check engine light. This may also occur if other engine issues cause the oxygen sensor’s signal to fall out of range. At MyMechanic Malaysia, we use advanced diagnostic tools to pinpoint the exact cause of the problem.
- Poor Engine Performance: The oxygen sensor plays a critical role in regulating the air-fuel mixture in your engine. A malfunctioning sensor may cause the engine computer to supply too much or too little fuel, leading to engine misfires, rough idling, or hesitation during acceleration.
- Reduced Fuel Economy: A bad oxygen sensor can cause the engine to burn more fuel, resulting in poor mileage. If you’ve noticed an increase in fuel consumption, it might be time to have your oxygen sensor checked at one of our MyMechanic Malaysia service centers.
How to Fix the Problem
Oxygen sensors can fail due to contamination from oil, coolant, or other fluids. If the contamination originates from a leak, addressing the source of the leak is crucial before replacing the sensor to prevent further damage.
At MyMechanic Malaysia, we avoid using carburetor cleaners, which can harm oxygen sensors. Instead, our trained technicians use oxygen sensor-safe cleaning solutions and tools for effective maintenance.
Replacing an oxygen sensor requires specialized tools, such as a scan tool for diagnostics and an oxygen sensor socket for secure removal and installation. While replacing the sensor may seem straightforward, it’s best left to professionals to avoid unnecessary damage. Our team at MyMechanic Malaysia is equipped with the expertise and tools to handle this effectively.
What Does an Oxygen Sensor Do?
An oxygen sensor compares the amount of oxygen in your vehicle’s exhaust gases to the surrounding air. This information is used by your car’s computer to maintain the proper air-fuel ratio and monitor emissions.
- Upstream Oxygen Sensor: Located before the catalytic converter, this sensor measures oxygen levels in the exhaust gases and provides real-time information to regulate the fuel supply.
- Downstream Oxygen Sensor: Positioned after the catalytic converter, this sensor ensures that the converter is effectively reducing harmful emissions before they are released into the atmosphere.
