What to Do When Both the VSA and Check Engine Lights Come On?

AvatarByCarl Frisch

The VSA light and check engine light are two of the most important dashboard indicators in any vehicle. The VSA light stands for Vehicle Stability Assist, and it is a system that helps to keep a vehicle stable when cornering or driving on slippery surfaces. The check engine light indicates a problem with the vehicle’s engine or emission system. If either of these two lights come on, it is important to take the car to a qualified mechanic as soon as possible so the issue can be diagnosed and fixed before it becomes worse. Both lights should be taken seriously, as they could indicate something serious or even dangerous.

Causes of VSA Light and Check Engine Light On in Automobiles

When the VSA light and check engine light appear simultaneously on an automobile, it is an indication of a possible malfunction. The Vehicle Stability Assist (VSA) system works in tandem with the Engine Control Unit (ECU), both of which are responsible for regulating the performance of a vehicle. Malfunctions may be caused by incorrectly installed sensors, faulty wiring harnesses, or corroded terminals.

Signs of Malfunction in VSA and Check Engine Lights

The most obvious sign of malfunction is when both the VSA light and check engine light illuminate simultaneously. This indicates that the ECU and VSA systems are not functioning properly and could be causing changes in the vehicle’s performance and handling.

Diagnosing the Problem – Troubleshooting Guide

The best way to diagnose the problem is to use an OBD-II scanner to read any error codes that may have been generated as a result of the malfunction. If no codes are present, then visual inspection should be conducted to look for signs of wear and tear or damage to any components that may have caused the problem.

Common Fixes for VSA and Check Engine Lights On

If loose connections or faulty wiring harnesses are found to be at fault, then they should be tightened or replaced as necessary. If corroded terminals or damaged sensors are identified as potential causes, then these should also be fixed or replaced accordingly.

Cost Considerations for Maintenance & Repair

When considering maintenance and repair costs it is important to factor in not only parts replacement costs but also labor charges from auto repair shops, as well as any time frame considerations for completing repairs. It is recommended that professional advice from a qualified technician should always be sought before attempting any repairs yourself.

This can save you time, money and the hassle of trying to figure out what is wrong with your car on your own.

Recommended Practices for Regular Maintenance & Inspection

For optimal performance, it is recommended that you regularly maintain and inspect your vehicle’s lights. This includes cleaning sensors in order to prevent contamination or malfunctioning issues that could be causing your lights to come on. Additionally, scheduling an annual visit to a certified auto mechanic for a comprehensive inspection is also recommended. This will help identify any potential problems early so that you can take the necessary steps to address them before they become more serious and costly.
