Why Is Acura TSX Check Emission System Shaking
Whenever you notice that your Acura TSX check emission system shaking while driving or whenever you’re waiting for the traffic lights idling, then it means there is a problem with your engine. So why?
When this happens, it means there is a problem with one or more of your engine components. This could be a faulty ignition coil, fuel supply, bad engine sensor, or bad spark plugs. But in case your car is only shaking while it’s idling, then the issue might be with the idle air control valve.
However, it’s not good to keep driving while your car is shaking badly. This could mean that you have a serious engine issue that you need to go for a car inspection.
Why Does My Acura TSX Say Check Emission System?
Your Acura TSX shows the check emission system because it is prompted by the engine control unit that manages the engine. This will happen when the control unit finds out that something could be wrong with your engine or something isn’t working well. However, various possible reasons could cause Acura TSX to say check the emission system. Below are possible reasons:
1.A Faulty Ignition System
The ignition system is what helps to start an engine. When there’s a fault with components like spark plugs, glow plugs, and coil cylinders, it can cause the CEL to illuminate.
2.A Faulty Emissions System
The emissions control is what monitors the carbon monoxide volume that the vehicle emits while in motion. Currently, car owners are now opting for eco-friendly vehicles to minimize carbon. However, the oxygen sensor is what is supposed to sense if the engine is burning too much fuel or less. Due to this, CEL will trigger to indicate that your Acura TSX is either running too much or less fuel or show that’s a problem with the sensor itself.
3.A Faulty Mass Airflow Sensor
One of the functions of the engine control unit is to calculate the quantity of fuel to add to the combustion chambers by following data from the mass airflow sensor. What this sensor does is gather information from the air filter, and once clogged, it can damage the sensor. When this happens, the CEL will illuminate.
4.A Blocked Diesel Filter
Your filter is what measures how gas passes easily through the exhaust. While gas passes, it must go via the filter. This will filter harmful particles from the exhaust. This is done by oxidizing the particles into a fine ash. One of the functions of CEL is to illuminate if this process fails, or when the filter becomes blocked.
What Does The Check Emission System Mean On Acura TSX 2006
In Acura TSX 2006, the check engine light simply signals that the onboard diagnostics system (or OBD II) has identified an issue in the vehicle’s emissions, fuel, exhaust, or ignition systems. This could be due to a loose fuel cap, spark plug, or even a faulty oxygen sensor which shouldn’t be ignored.
As you may know, there are onboard diagnostics in all cars and light trucks that are supposed to identify engine-related issues that might affect the emissions control systems.
Note that when the check emission system light stays on, it simply means that there’s a problem. But if the check emission system light is flashing or blinking instead of being illuminated, then it indicates a serious problem that you must solve immediately.
How Do I Remove My Emission Control Light?
The first thing to do is to drive the car to your mechanic for a full inspection of the problem and probably turn off the light. But most times, the light won’t turn off immediately, then here are the steps you can take to remove the emission control light.
- Go to the Negative Terminal: There’s a (-) sign and a (+) sign in the car battery, so locate the negative terminal as indicated.
- Take off the Negative Connector: The nut of the negative connector needs to be loosened before you can remove it.
- After some time, then reconnect: You should wait for 30-60 seconds before placing it back in, then tighten the nut to the battery again.
As you can see, the easiest way to remove the emission control light is to reset it. But if this didn’t work, then you need to consult a professional mechanic who will reset the light for you.
What Does Check Emissions Light Mean On An Acura?
When the check emission light in Acura TSX gets illuminated, it simply means that there’s a problem. But if the check emission system light is flashing or blinking instead of being illuminated, then it indicates a serious problem that should be attended to as soon as possible.
What Does It Mean When It Says Check Emission System?
Your check emission system light is what shows that the onboard diagnostics system (or OBD II) has found one or more components in the vehicle’s emissions, fuel, ignition, or the exhaust system not working properly. Note that all cars and light trucks have onboard diagnostics installed on them, which is supposed to detect any engine-related issues that could affect the emissions control systems.
What Does The Check VSA System Mean On Acura TSX?
The Acura TSX cars are developed using VSA which stands for Vehicle Stability Assist. This is the system that’s designed to keep drivers safe while driving in hazardous conditions. This VSA is simply an indicator light, and whenever it turns on, it means your Acura TSX requires immediate attention.
Whenever the VSA light remains on, it indicates to you that there’s an issue with your Acura TSX. When this happens, it’s time to take it for inspection.
How Do You Reset The Check Engine Light On An Acura TL?
There’s a possibility to reset your car’s check engine light by disconnecting the battery, especially if your car is manufactured before the mid-1990s. In modern vehicles, there’s a feature that can simply turn the light back on once the battery has been reconnected.
Note that doing this yourself isn’t too difficult especially when you’re wearing safety gloves and safety glasses:
The first thing to do is to allow your vehicle to cool down. This is because you are required to access the battery, so ensure the ignition is turned off and allow your engine to cool down completely.
Locate the Negative Terminal: Inside your engine, you’ll find a (-) sign, and a (+) sign in your car battery, so locate the negative terminal as indicated.
Pull off the Negative Connector: You can do this by first removing the nut of the negative connector before you can remove it.
Wait a while and then reconnect: You need to wait a while for about 30-60 seconds before putting it back in, then tighten the nut to the battery again.
Please note that when you disconnect the battery of your car, it will erase all the vehicle’s computer data. But if the reason for turning the check engine light on an Acura TL is because you want to pass an emissions test, then this procedure may not work for you. This is because even if you succeed in clearing all emissions data from the computer when the battery is disconnected, your vehicle’s system requires a series of test run before it can pass the emission test.
Can I Drive With An Emission Problem?
You won’t find any right or wrong answer to this question. This may depend on the cause of the emissions light. However, it may be safe to drive while an amber check engine light is flashing in your dash. But it’s always safer to understand the reason why the emission light was turned on, even if it requires taking the car to a mechanic for inspections.
As you know, the emissions control in your car reduces the number of toxins that come out from your vehicle into the environment. This means that it’s vital to get it rectified as soon as possible to keep our environment safe.
How Do I Fix My Emissions Problem In Acura TSX?
Like I said before, the emissions control in your car reduces the number of poisonous gases which come out from your vehicle into the atmosphere. So it’s always important to ensure the emission control systems in your car are perfectly working. Below are the steps to fix your emissions problem in Acura TSX.
Step 1. Examine the air filter found on the air cleaner system. The filter is what helps to filter dust, dirt, and other external particles from the air stream and prevent them from going into the engine. Once the filter is clogged or used for a year, it needs to be replaced. You can clean the housing air filter of dust and debris by using a clean rag.
Step 2. Check the PCV, which is the Positive Crankcase Ventilation system. It is what redirects gases in your crankcase into the intake manifold which helps in reducing air pollution and sludge buildup in your engine. Just check if the PCV valve is broken, clogged, or missing hoses.
Step 3. Inspect the EVAP, which means Evaporative Emissions Control system. This EVAP is what helps in preventing toxic fuel vapor from spreading into the environment. You can check your hoses, fittings, and canister if there’s any damage. However, depending on car models, some canisters are equipped with a filter that can be changed when black or clogged.
Step 4. Locate the EGR, which stands for Exhaust Gas Recirculation system. This is what reduces the produced emissions during the combustion process whenever there’s a very high temperature. This EGR system allows exhaust gases to go into the intake system to minimize combustion temperature. So check for vacuum hoses damage, restricted pipe, valve operation, and passages.
Step 5. Examine the Air Injection System in your car if your particular car model is equipped with it. It is what injects fresh air into the exhaust ports to help consume unburned, which minimizes HC and CO. So check for damaged hoses, valves, lines, and belt tension.
Note that the converter doesn’t need maintenance, but the exhaust pipes and connectors that lead to the converter must be examined for leaks. In case you have been using the catalytic converter for 5 years or more, ensure you inspect it to be sure it is still working perfectly and not blocked. Note that a clogged converter minimizes engine power and causes it to overheat.
Conclusion. The Acura rdx Check Emission System or malfunction indicator lamp light can be triggered in Acura. When this indicator light illuminates, resetting it will be one of the options and I have shown above How to reset the check emission system Acura TSX but if it doesn’t work, then your vehicle needs to be taken to a mechanic for full inspection.
