I have a 2001 corolla myself with the check engine light on for awhile. these cars are notorious for having bad o2 sensors and Mass air flow sensors. These are parts that help the engine utilize gas properly, basically energy conserving, pollution reducing parts. From my experience the car runs fine with the light on as long as it is these problems. You could take it to an autozone and have them run the codes for you and you could make sure that is the problem, but i have read a lot of forums that speak to this issue. you can also clean the MAF sensor with some Electrical cleaner (found in auto section of Walmart). Goggle the problem and you can find step by step toturials that walk you throught DIY process. It is really simple actually. The O2 sensor might need to be replaced make sure you get the OEM part and not the universal.

What is a yaw rate sensor & how does it affect braking?


This sensor detects a deviation of the vehicle from the centerline of the vehicle such as in a skid, the computer which is part of the skid control and abs system then adjusts the brake and throttle to pull the car out of the skid, the driver is not in control at that time until the vehicle skid is recovered, it is also a deceleration sensor. The yaw rate sensor does nothing under normal conditions

Anti skid


So you have several problems

Why ask ! Read your owners manual?

What do you usually do when you have a vehicle problem?

Go to a repair shop, so they can diagnose any & all things you
want to know about & are having problems with

Have to look at scan tool data

Check for codes & diagnose & resolve those issues first

You have an engine performance issue & an abs braking system
fault

Do you not go to a shop when things do work correctly?
Have to do that,road test & look at data

Most folks just drive & never do any Preventative Maintenance,
so no wonder problems come up to haunt you, a couple times

My car is showing a message on the display. it shows ''Check VSC" what is the meaning of this message?


"vehicle skid control". If "check engine" light is on , it will set the "vsc" light. Have all "engine" and "abs" codes pulled.

Parking Brake, ABS, Traction Control & Anti Skid lights on


One or more of the sensors in the wheels that are responsible for these functions is faulty. It is sending a signal that is mucking up the calculations that control the brakes and engine for traction control and anti skid. All of them need to be checked!

My check engine light went on & i noticed i got sluggish and was running 4000 rpms at 50 mph


Hi there:
When the light comes on, one or more diagnostic trouble codes (DTC) are stored in the engine control module. These DTCs remain even if the light goes out. To address a Check Engine Light problem, the DTCs are retrieved and the appropriate troubleshooting information is followed in order to determine the problem.

The Four Most Common Check Engine Light Scenarios and What to Do:
* The Check Engine Light turns on and off or flickers.
If the Check Engine Light comes on in the city but goes off on the freeway, then the fault is present during city driving conditions. Pay attention to whether or not the vehicle runs or drives any differently when the Check Engine Light illuminates. If vehicle performance does change, drive the car as little as possible and take it to be checked by a service professional as soon as possible. If there is no change in vehicle performance, you can drive home, but have it inspected as soon as possible. In this condition, you run a risk of the vehicle dying or not starting.

* The Check Engine Light comes on and stays on.
If the Check Engine Light illuminates constantly during driving with no noticeable driving or performance problems, there is a permanent fault in the emission control system. When this happens, the computer that controls the emission system usually has a backup program that runs while the fault is present. (These backup programs are often referred to as "limp home" mode programs.) You should get the vehicle serviced as soon as possible, but in most cases, the vehicle will continue to operate, though you run a risk of it dying or not starting.

* The Check Engine Light illuminates, stays on, and there are performance problems.
This means that a vital component of your emission control and engine management system has a serious problem. It usually involves a component or system needed for the vehicle to run at all. In most cases, drive the vehicle as little as possible. In many cases, the vehicle is not safe to drive at all -it could stop or stall out at any moment. It is best to pull over to a safe place and have the vehicle towed to an automotive diagnostician for a thorough inspection and repair.

* The Check Engine Light light comes on and blinks in a steady pattern while driving.
Don't confuse this steady pulsing of the Check Engine Light light (usually one or more flashes per second) with a flicker (see above). The Check Engine Light may stay on steadily or it may flash when the vehicle is accelerated. This is very serious. There is a severe failure of the emission control system that is causing the engine to misfire to the point that the catalytic converter is damaged each time the Check Engine Light flashes. It may mean that the catalytic converter is overheating to the point that it will glow red or, in extreme cases, start a fire on the underside of the vehicle. Immediately pull over to a safe place and have your vehicle towed to an automotive diagnostician for repair. Vehicles can be severely damaged and even destroyed by fire if this condition is ignored for too long.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

The engine management light is on, and the air bag light is illuminated in red on the dash. The heater is not blowing hot air, although the coolant level is fine. There is a 'whirring' noise


I suggest scanned the computer car in order to know what fault codes is stored there.

2001 Lexus LS430. when I start the car most times it's fine, but when I take off from Park to Drive the SKID CONTROL Light comes on and beeps and the vehicle starts to brake on it own (Quiet Freak


You must have the dealer scan the system with a special tool to see what is causing this unwanted activation of the vehicle stability control system.

When the vsc trac light comes on my 2003 Toyota 4 Runner, what does that mean?


As long as it does'nt stay on it's doing what it's suposed to be doing which is saving you from going out of control. It'll come on more often if you drive like hell, run with low tracktion tires or worn out ones and if the air pressure is low. If your tires have over 80,000 miles on them even if the tread is still good their bad tires as their skating along and the trackstion system is working hard to keep the car under control. If the tires aren't al the same size it'll do it to. ( fronts worn out backs still with tread.) Mis matched tires too. Ifthe light stays on other light's are bound to be coming on too the ABS light the brake light, and even the engine light as their all involved in traction control.

What does VSC stand for when light comes on?


If you are talking about the "VSC Off" light, it means that the button to disengage your cars Vehicle Stability/Skid Control" system is engaged. Press the VSC button, the system should reengage, and the light should turn off.
If you are talking about the other VSC light, it means that your car has been forced to take evasive action to avoid a dangerous situation. For example, if you are driving on an icy road, and take a turn too tight, the vehicle may be forced to apply pressure to one of the brakes to prevent the car from loosing control. In this situation the VSC indicator light will light up to alert you that the action was taken, and remind you to possibly slow down.
