SOURCE: engin managment system light keeps coming on and off

The best ideea is to scan your Engine Control Unit with a VAG-COM, Bosch KTS, ... diagnosis tool. If you have one of these dedicated scan tools you will find definitely the engine fault code-"P...." and the clear description of the error. Also you can try to erase this error (or these errors) from the Engine Control Unit memory. If errors are "sporadic" type you certain have permission to erase them, also for some kinds of "static" errors. Because your Engine "MIL" - Malfunction Indicator Lamp keeps coming "ON" and "OFF" you have a big good hand to clean errors from Engine Management System memory. If you don't have any diagnosis tool, you can also try something else. For check up if the engine have a proper turn, you can successively disconnect each spark plug coil from the engine wiring system, engine idle, car stationary. When you operating this you must be free of chassis ground (battery ground)!!! When you disconnect a spark plug coil and the engine speed (rpm) drops, that means this coil works properly. When one coil disconnected and engine speed (rpm) still remain unaltered, this coil (or spark plug) is out of order. First you can change only the spark plug and check up again. If no changes the coil is defective and must be replaced! My recommendation is first to change all spark plugs on the engine, and after that check up coils. Please Rate my Response! Thanks!

Engine management light reset


The car is trying to tell you something - limp mode is there to protect the engine if a serious problem is detected. Stop driving it and get someone out to scan the codes and diagnose this.

Check engine light problem on 2004 Pt Cruiser. Car keeps stalling, what can I do??


Hi there:
First, it is normal for the check engine light to come on momentarily when you turn on the ignition switch and then go out. If it stays on, then you have a stored code that indicates a malfunction of some kind in your engine or transmission control systems.


* 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.



I suggest visit some Autozone or AutoShop with OBD Scanner Reader in order to scanning the module to know exactly wat fault code is stored there; note this code number for additional details.


Hope this guide helps.

Check engine light comes on when downshifting on a hill; then shuts off when I back off


Hello
When the service engine soon light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.

Check engine light on


Check all the usual things, oil water etc, but you will have to have a diagnostic check done to reset the engine management system (it will stay on your dash if you don't) if all ok, but it will tell you if there is a fault

EMS light on 2007 Jeta


EMS stands for "Engine Management System. Please read on.
Lots of areas are monitored by the engine management system, some of them are not apparent to anyone just driving the car, and usually they are not immediately terminal (which is why the light is yellow and not red). However they can get worse and should be checked as soon as possible. The following tells you a bit about engine management systems and how to read codes/ reset them.

The 'Engine Management Light' come on if the automatic monitoring system detects a malfunction in (usually) the powertrain components of the vehicle. If the fault has been fixed, then what you need to do to put the light out is:-

1 Disconnect the battery.
2 Reconnect the battery - this resets the engine management to its base configuration.At this stage, if you start the car up the Light will still be on and will stay on until the monitoring system has completed a series of tests some of which depend upon the car being operated under various normal driving conditions. Typically this will take about 20 minutes of normal driving. If all the tests are within spec then the light will go out and you will be back on the road!

If the fault persists then you have a specific problem. You will either need to take it to a dealer who will be able to read the codes and fix the problem (lots of dosh outlay I suspect). If you are reasonably confident you could buy a code reader to find out the problem for yourself. Gendan are currently selling theirs for £39.95 free pp which covers all post 2001 petrol and post 2004 diesel cars. Note if you reset using a code reader you still have to go through the 20 minute drive process before you are "back in business".
