The VSA system is the "Vehicle Stability Assist" system, which is essentially your vehicle’s traction control system and ABS systems. The traction control system monitors the steering and stability of the vehicle and engages when loss of traction has been detected. This is done by the use of electronic sensors at each of the four wheels that communicate with the Powertrain Control Module (PCM) regarding steering performance and stability in adverse weather conditions. The traction control system works by reducing engine speed and determining which wheel to apply brake pressure to in order to prevent the vehicle from sliding. The anti-lock braking system and the traction control system work together to maintain the stability of the vehicle. The computer uses this information received from electronic sensors regarding the rotational speed of each wheel, the horizontal motion of the vehicle, and the vertical motion of the vehicle to determine how to direct the traction control system or the anti-lock braking system to best control the vehicle when needed. When this warning indicator light comes on in the dashboard, this could be an indication of several issues such as faulty wheel speed sensors, a faulty steering angle sensor, a faulty rotational speed sensor or a problem with the steering rack. In some cases, the traction control system may simply need to be reprogrammed. The check emissions system light may indicate a number of things raging from the catalytic converter to an oxygen sensor, both of which are part of the emissions control system. I would recommend having a professional from YourMechanic come to your location to take a look at your vehicle.
How to Identify and Fix Common car Problems ?

The easiest method to reset the check engine light is to drive your car as you normally would and let the light turn off naturally by itself. If it hasn`t turned off after three days, turn the car on and off three times consecutively.
Clean or replace our vehicle`s air filter to prevent debris or contaminants from getting into your fuel or exhaust. Try replacing the oxygen sensors under the hood and on your exhaust line if they`re faulty and taking incorrect emissions readings.
Some common causes for the emission light on car illuminating are: Emission system fault – This is when the engine is burning too much fuel, increasing your carbon footprint. The emission light on car could also be on because the system is not burning enough fuel, or if the sensor is broken.
(ESC) System. Helps to stabilize the vehicle during cornering if the vehicle turns more or less than what was intended. It assists in maintaining traction on slippery surfaces by regulating engine output and selectively applying the brakes.
Error Code P0440 indicates a malfunction with a vehicle`s EVAP system. This means that the vehicle`s engine control module (ECM) has detected a leak in the fuel tank vapor system or that a vapor pressure sensor has malfunctioned.
So, is it safe to drive with the Emissions Control Light on? Yes, as long as it is the only light that has come on, you do not have to worry about your safety.
Potential solutions include leveraging photosynthesis in coastal plants, seaweed, or phytoplankton; adding certain minerals to seawater that react with dissolved CO2 and lock it away; or running an electric current through seawater to accelerate reactions that ultimately help extract CO2.
It is not good when there is an emissions problem or exhaust system failure. It can cause performance issues in your engine, potentially leading to costly internal damage. It`s also bad for you and the environment when harmful fumes and carbon monoxide are getting out more than they should.
These gasoline vapors may produce errors in the emissions system, which would cause the check engine light to come on. Dirt and Grime that gets into the gas tank could also contaminate the fuel injectors. Perhaps the biggest sign of a bad gas cap is the smell of gasoline in your vehicle.
The main culprit? A faulty exhaust. Usually, your exhaust and catalytic converter work together to limit the amount of harmful gasses your engine produces. However, when your exhaust is old, worn or damaged, it`s much less effective at doing so.
A faulty catalytic converter leads to emissions system problems. It cannot take enough carbon monoxide and transform it into carbon dioxide. If your catalytic converter accumulates trapped gases in the engine, you can be exposed to the smell of sulfur just like rotten eggs.
VSA will only come into play when it is needed. In other words, when your tires are slipping. It will not slow you down in normal driving, or even hard accelerating straight ahead.
VSA is turned on every time you start the engine, even if you previously turned it off. If you turn VSA off, your vehicle has normal braking and cornering ability, but VSA traction and stability enhancement become less effective.
The EVAP system leak error means the sensor detected the Evaporated fuel in the gas tank is leaking. If this fault is detected multiple times, it is recommended to have the vehicle serviced by a mechanic to resolve the leak.
An EVAP leak can cause a variety of issues, including a decrease in fuel efficiency, an increase in emissions, and a decrease in engine performance. If left unchecked, an EVAP leak can also cause damage to the catalytic converter, which can be expensive to repair.
If the check engine light illuminates, it will either blink or remain constantly illuminated, depending on the problem. A blinking light, or in some cars a red light instead of a yellow or orange light, indicates a problem that needs immediate attention. Either way, you should have the vehicle checked by a mechanic.
In general, you will need to drive between 50-100 miles after you clear your car`s computer. Hopefully, this will get rid of the check engine light once and for all. If it doesn`t, there may be a more critical factor causing this item to turn on.
Disconnect both O2 sensors (front and rear). Start the engine and allow the vehicle to idle. After faults have stored: Cycle the ignition OFF/ON 2 times with a 10 second pause in between key cycles.
The easiest way to perform an ECU reset is by removing the fuse from the fuse box. It is a very simple process, and all you have to do is pull out the car key, remove the fuse from the fuse box, and then put it back after about 15 to 20 seconds. Doing this clears any long-term memory stored in the car`s ECU.
Like desktop computers and most other electronics, disconnecting the battery cable for a short period will not fully reset your ECU due to the residual power remaining in the circuits.
The least invasive way to diagnose your ECM is to connect an onboard diagnostic (OBD or OBD II) tool to the diagnostic port. From there, you can scan to see if your engine computers have produced any error codes. There are many of these codes, and your diagnostic tool`s manual should have information on what they mean.
Driving with Bad Catalytic Converter
If you`re noticing sluggish engine performance, reduced acceleration, a smell of rotten eggs or sulfur from the exhaust, dark exhaust smoke, or extreme heat coming from under the vehicle, these are symptoms of a clogged Catalytic Converter, and it should be repaired soon.
They are particulate matter (often referred to as particle pollution), ground-level ozone, carbon monoxide, sulfur dioxide, nitrogen dioxide, and lead. These pollutants can harm human health, harm the environment, and cause property damage.
The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity, heat, and transportation.
