Car goes into limp mode when the check engine light and VSA light comes on
Car hesitates to start which causes the check engine light and VSA light to come on puts car into limp mode. Check engine light flashes when driving but stops when in park. When car is put in nuetral and accelerator is presses check engine light begans to flash. Goes off after ignition is started several times. What causes this and how can it be fixed. Had starter replaced last year.
My car has 174100 miles.
My car has an automatic transmission.

Well, VSA stands for Vehicle Stability Assist and is Honda`s computer system that helps ensure the tires have traction to help keep you on the road. When both the check engine light and the VSA light are illuminated it means that the computer has detected there may be a fault in the system.
Limp mode occurs when your car`s electronic control unit (ECU) senses something drastically wrong with your transmission or engine. To get your Accord out of limp mode, add transmission fluid, run an onboard diagnostic, or take your vehicle to a mechanic.
The limp mode is generally activated by a system failure which causes it to overheat. The check engine light will flash or illuminate; in some cases, the screen will also tell you why the limp mode is used. If the engine has overheated, it is best to pull off the road to a safe spot and let your car cool down.
If you see the VSA light blinking on your Honda`s console, there`s no need to worry that it`s a fault or other warning. The flashing light simply means that the system has activated and is helping the car to steer more safely.
Vehicle Stability Control is, technically, what VSC stands for. When suddenly turning onto slippery roads or swerving, a driver can better control skidding thanks to this system. A warning light on the dashboard will flash when this system is on/activated.
There is a “connection.” When you drained the battery, the PCM and possibly the electronically controlled VSA components themselves “saw” an out of range low voltage, even if momentarily. Such will cause a trouble code to set and illuminate the warning light. It is a known issue.
The eighth-generation Accord sedan and coupe (2008 to 2012) have received numerous complaints about excessive brake wear and noise, high oil consumption, engine misfires, and air conditioning problems. The oil consumption and misfire issues seem to be caused by faulty piston rings.
Limp mode is activated when the ECU (electronic control unit) notices that something is not operating within predefined parameters, this can be caused by a variety of factors such as: Extremely low levels of oil or coolant. Transmission errors – such as when the gearbox can`t change gears properly.
While entering limp mode is geared to protecting your vehicle from additional damage, should you choose to ignore the warning signs and continue to drive the vehicle for prolonged periods, the engine can overheat, generate further warning lights, and ultimately refuse to start again if you switch the engine off, so don …
If you see that warning light triangle with an exclamation mark appear there`s a simple explanation. This icon stands for your Honda vehicle`s Vehicle Stability Assist system and will illuminate your dashboard when an issue with the system is detected.
Press and hold the VSA OFF button until you hear a beep to turn VSA on or off. The VSA OFF indicator appears when the system is off. Traction control stops functioning, which may make it easier when trying to free your vehicle if it is stuck in mud or snow.
It is safe to drive your Toyota while the VSC OFF light is on, however, we recommend cautious driving, especially in poor weather.
VSC System OFF and Check Engine Light is On
If you notice that the “VSC Off” icon is on, don`t worry because your car is still safe to drive. But, you must be careful on the snow or slippery road because the car won`t stabilize itself.
If the low tire pressure indicator comes on, or the multi-information display shows a “CHECK TPMS SYSTEM“ message, the VSA system automatically turns on even when the VSA system is turned off by pressing the VSA OFF switch (see page ).
A bad battery can cause problems in electrical and electronic parts, including the computer. It can even cause a “Check Engine” light.
Yes it can. Depends on the vehicle. Some cars with electronically controlled transmissions will put the transmission in limp mode if it can`t get a speed signal from the brake/slip control computer, which gets a vehicle speed signal from the wheel speed sensors.
Clear the check engine light
Use a reliable OBD2 scan tool to clear fault codes and reset limp mode. Just plug into your OBD2 port and search for the correct function.
An engine that is hesitating to accelerate is most likely dealing with a fuel/air mixture that is too lean. Engine`s that are running inefficiently will begin to show signs like hesitation which will only become worse over time.
As mentioned earlier, the sixth generation and early seventh-generation Accords were riddled with problems. Anything from the 1998 model to the 2005 model is all Accord model years to avoid. The transmissions and engines were prone to failure and excessive oil consumption.
One of the most common reasons a car goes into limp mode is a problem with the fuel system. If the fuel pump isn`t working properly or there is a blockage in the fuel lines, the engine may not be getting enough fuel. This can cause it to run rough and eventually go into limp mode.
A faulty EGR valve can result in excessive carbon/soot at the turbine end of the turbo charger. This could cause the VNT mechanism to become clogged and stick which in many cases will cause engine management lights to appears along with reduced performance known as “limp mode”.
Take your vehicle into your local Toyota service center to have a certified technician run the codes and pinpoint the issue. It is safe to drive your Toyota while the VSC OFF light is on, however, we recommend cautious driving, especially in poor weather.

When that warning light triangle with an exclamation point pops up, there`s a simple explanation. It means that there is something wrong with your Honda vehicle`s Vehicle Stability Assist (VSA®) system. This system helps to stabilize the vehicle during cornering if the car turns more or less than desired.

There are many possible codes it can be so the additional testing will be needed to isolate the cause of the problem.
Engine Light and AT light. Car goes into limp mode
ANSWER : Hello. Most of the time this is the result of a transmission failure. It is common for this transmission to have internal pressure problem which will cause these codes. It can also be a voltage problem so I always check that first. I check the voltage going to the transmission and if it is too low I repair that issue which is commonly the ignition switch. If the voltage is fine, then the transmission pressures need to be checked and it will more than likely need to be replaced. I would have a transmission specialist look into this.
While driving on freeway truck goes into a limp mode, and the check engine light, abs light, parking break light, service brake
ANSWER : It is possible that you could be having an issue with your powertrain control module. This is somewhat of a common problem on many GM vehicles. I would recommend having your vehicle inspected by the dealership to determine if the powertrain control module is functioning properly. If not, a reflash of the powertrain control module may resolve the issue but often times it must be replaced.
2007 Honda Pilot Check Engine Light and VSA light on and idling at higher RPM, problem with acceleration
ANSWER : Hi there. The Vehicle Stability Assist light typically will trigger when the system has been disabled and it not the source of misfiring or acceleration issues in most cases. Since your check engine light is illuminated as well, it is highly probably that the root source of this issue will be discovered by having a professional mobile mechanic complete a check engine light inspection. This will permit them to download all stored error codes and correctly diagnose the root issues your Honda Pilot is experiencing and recommend the right repairs.
Battery light goes on when I start car then turns off, if I rev engine light comes back until rpms go down. Abs goes comes on/off
ANSWER : Batteries can die due to faults in the charging system so ideally a suspected "faulty" battery should be load tested before a decision is made to condemn it. The only exception to this rule is if the battery is already clearly "old" (greater than 5 years) but even then once you put a new battery in, as a replacement for a "dead" battery, you have to comprehensively check out the charging system. Diagnostic Trouble Code P0460 will result in disruption of the dashboard fuel gauge’s ability to accurately report your tank’s fuel levels. The fuel gauge readings may be erratic, or read somewhere off scale. Vehicles equipped with a low fuel warning light feature may also suffer from erratic low fuel warnings in the event of a code P0460. Unless the P0460 code has been reported alongside other trouble code, all of the vehicle’s essential systems should otherwise function normally. I would recommend that you request a check engine light diagnostic to first resolve the fault causing the P0460 code to set. The check gas cap light warning light could be due a faulty gas cap and/or small leaks in the EVAP system.
Car won’t start. The check engine light, battery light, and oil change light are coming on. I tried jumping the car and nothing happened. Why won’t my car start?
ANSWER : Hi and thanks for contacting Your Mechanic. If sometimes your vehicle will start with the new alternator and sometimes it won’t, then there is a loose connection in your charging system. Check all of the wires to the alternator and to the battery. Make sure that the battery cables are clean and tight. Make sure that the wires to the starter are clean and tight. A loose ground to the ignition system will cause the vehicle to not crank over. Check all of the ground wires from the battery to the starter. Make sure that they are clean and tight. If you need further assistance troubleshooting your no start situation, then seek out a technician, such as one from Your Mechanic, that can assist you.
Check Engine light comes on when cars RPMS go over 4000 error code P0344
ANSWER : Hi there. This code is for a bad camshaft sensor. It can be caused by a bad sensor or it can come from another issue. I usually check the sensor first and then I check the timing belt. Most of the time this code is for a worn out timing belt. If the timing belt is fine then I check the crank sensor also as it can cause a camshaft sensor code if it is not reading correctly. If you want to have this looked at, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose the trouble code firsthand and make the necessary repair.
Engine management light comes on and goes of again when the engine is warm car can also go into limp mode when cold, when warn ok
ANSWER : Hi there. Those codes are what is needed to begin properly diagnosing what is occurring. When there is a fault, the computer sets a code, but it does not know why the fault occurred or what is causing the fault. It is obviously a cold start concern that corrects itself once warm, but there is no verifiable why to determine what is causing the concern until the codes are retrieved and diagnosis properly completed. I suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several technicians available that can assist you with a check engine light inspection.
