There is a problem, it needs to go to a factory service center, it can be any one of multiple reasons that turns this light on.

SOURCE: 2001 volvo s60 t5 - performance reduced warning message, limp mode activated

I had exactly the same problem on my UK 2001 S60.
It was caused by the throttle control housing gaskets not being serviced properly and consequently the entire housing had to be replaced - not a cheap job -and a valuable lesson learned - use a reputable volvo specialist to service your volvo - I didn't and I learnt the hard why! only a volvo specilaist would have known about this I went to several other main street garages & none of them could even diagnose the problem let alone fix it. Although they did do numerous other things first before they gave up - ie replaced titanium spark plugs.
Before it stoppped running altogther and went into "limp home mode" there were tell-tale engine/throttle surges when the car was idle, but in gear.
It is now running "like new" & I will never get another garage to service it, as this could have been avoided - however they can also wear out after about 10years - so my bad services just made it happen sooner!
I hope this helps!

SOURCE: check engine light is on,display says restricted performance

Anything can cause the check engine light to go on from a loose gas cap, to a transmission issue. When the onboard computer detects an issue, it will restrict performance so as to not damage the engine any further. An Oil change won't affect this light. The only way to determine the cause of the light is to have the computer scanned with an OBD-II tool (Autozone does this for free) to determine the codes and cause for the light. You can also clear the light with the OBD-II tool, but if the problem is still there, the light will just come back on

How do I clear a service emissions message on a 2005 Mercury Mariner with a 3.0L engine. I have performed the required maintenance procedures at both 30,9000090's and 60,000miles. Still have message.


Warning Messages The warning messages can interrupt the display until cleared or reset by the driver. The warning messages are either single cycle, non-resettable, or repetitive warning messages.
The single cycle warning messages display once whenever the ignition switch is turned to the ON position or a fault occurs in a system, and can be cleared by pressing the RESET button. The single cycle warning messages are:
  • liftgate ajar
  • liftgate glass ajar
  • service emission system
  • low brake fluid
  • service brake system
  • check left headlamp
  • check right headlamp
  • check left turn lamps
  • check right turn lamps
  • check left high beam
  • check right high beam
  • check brake lamps
  • check parking lamps
  • washer fluid low
  • check fuel cap
  • change oil soon
  • change oil now
  • low fuel
  • service 4x4
  • turn signal on

Motor engine Light staying on when car moving


I think you mean you have the Check Engine warning light displaying once you have started the engine.

If this warning light is displaying when driving the car there is an irregularity with the engine operation.

You need to take the car to the dealer or other competent service business so they can hook up a scan tool to the vehicle and see what fault codes the computer is generating and what other irregularities are apparent with the engine operation.

Don't delay getting it checked out or the onboard computer could send the vehicle into "limp mode" as an engine safeguard measure if the problem gets worse.

There are multiple causes(dozens) for a CE warning to display and it needs to be properly diagnosed so the correct repair can be undertaken. Even relatively small and easier to repair problems can still cause a CE warning to display such as a vacuum leak or the failure of a sensor unit. So get it checked out ASAP.

Can i drive my vw golf whilst having fault codes p1006 and p2101


Yes you can for a short time but you will get a check engine warning light if it is not already displaying.
If you don't attend to these issues you will very likely have very significant performance problems with the engine .

Don't put off having the car fully scanned by a VW service center because it could be generating other fault codes as well as the 2 you have mentioned and you need to have the causes properly diagnosed and repairs done.

Peugeot 2007 depollution system faulty warning light


Sadly a common fault with 207s is random fault warnings coming up on the display.

If it's a real fault, then you should notice a fall off of performance and this indicates a trip to your garage to get it fixed.

If the fault comes and goes, or there is no loss of performance, do what most 207 drivers do and ignore it !

What is the problem of my mitsubishi lancer why the "SERVICE ENGINE SOON" still warning on?


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.

Engine warning light


Hello and welcome to fixya.com
turned on by the systems computer it is to alert you to the fact that the computer module has detected a fault in the systems operation, this can be the engine, the emissions system or the transmission. What must be done now is to have the system scanned for fault codes, these are called OBD2 fault codes, then diagnostics are performed to determine the cause of the fault codes and repair made based on the diagnostics performed.

My 2204 jaguar s-type v6 with 115,000 miles has the amber engine fault icon on. The car is driving normal. What is causing the light to stay on all of asudden?


you may find this light comes on and then suddenly goes off again, This is caused by a monitoring alarm in the OBD II system that is sensing a fault as it carries out its constant series of checks on the engines performance during a set driving cycle. If the fault is not detected on the next driving cycle the light will go out. The most common reason for this particular fault is the MAF (mass air flow sensor) this can sometimes read out of range (due to dirt or sudden changes in air condition) Get the codes read as this fault will be logged in pending codes if the fault has disappeared or as a current fault if still displayed. Don't panic - just get the codes read !
hope this helps - good luck.
