How-To Troubleshoot Check Engine Lights
Examine The Catalytic Converter
The catalytic converter is a vital component that plays a leading role in controlling the emission of toxic pollutants from your vehicle. The combustion process produces a lot of contaminants, and the catalytic converter is responsible for converting them into less harmful substitutes before they are released from your vehicle. Often, due to the nature of the job, the catalytic converter tends to get clogged up, which affects its working, leading to the illumination of the check engine light. Get your catalytic converter examined at our garage near you in Walnut Creek, CA, to easily sort out the warning light problem.
Oxygen Sensor Inspection
A host of sensors in your car are meant for specific purposes. The oxygen sensor monitors the amount of unburned oxygen in the exhaust. This data is sent to the onboard computers to change the air-fuel ratio for optimal combustion. A malfunctioning O2 sensor will send erroneous data, adversely affecting the engine, leading to a flashing check engine light. Contact us at M Service, Inc. to get your oxygen sensor inspected by our professionals immediately.
Check The Exhaust Gas Recirculation Valve
Most of the time, the illumination of the check engine light is caused by problems in the engine's functioning. These problems might directly or indirectly impact the engine, and the same holds for your vehicle's exhaust gas recirculation (EGR) valve. As the name suggests, the EGR valve is meant to recycle unburned fuel back into the combustion chamber for complete burning, and problems in its functioning adversely affect the combustion process, leading to the warning light illumination. Getting your EGR valve replaced is going to fix the problem.
Keep Tabs on the Battery
At times, the illumination of the check engine light might not have anything to do with your car's engine because a malfunctioning battery can also trigger the warning light on the dashboard. This is because the battery is responsible for providing the other electrical components in your vehicle with the required amount of charge for their efficient functioning. Due to a failing battery, most electrical components will face issues. You must conduct periodic testing of the battery in your car to ensure it works without a hitch.
