Check Engine Light

Yes

Disconnect the battery for about an hour, then hook it back up. If it comes back on, something is wrong.

No, but you will fail an emissions test.

Just a cheap scan tool can be bought at any auto parts store, e.g., NAPA, Auto Zone, etc. They have some which are OBD1 and OBD2 compatible.

The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to AutoZone or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.

The check engine light comes on when the computer has detected a problem with the emissions system. The engine maintenance light comes on when the engine needs some scheduled maintenance such as an oil/filter change.

Sure you can drive it, and you can also do serious damage to the transmission by doing so. Do exactly what the light says. Have the transmission checked by a professional.

That light notifies you that one of the gauges is out of its normal parameter. Check the temp (overheating), the voltage (not charging) and the oil pressure gauge (low or no oil pressure).

No, the Check Engine light will only come on when you have an emissions related problem.

Every sensor on the engine and transmission can cause the light to come on.

For a 1994 mercedes that is running an older OBD 1 series computer it is hard to find scanners for. Normally all you would need to do is use a paper clip and cross two connections and watch how many times your dash lights blink and that will give you your error code.

The engine light on followed by one chime in a PT Cruiser is a notice to the driver that something is wrong in the engine. The chime sounds only to make sure the driver notices the engine light.

The check engine light will tell you when the computer has picked up a problem and is usually emission or transmission related. Have the computer scanned for trouble codes and post back to me with the codes and we can go from there. Most local auto parts stores like Auto Zone or Advance auto parts will read the codes for free. transman

After repairing the cause of the code, you can clear it with a scan tool.

That sounds as if it is a diesel pump with water coming from bottom. This would be indicator of water in fuel filter located above starter motor. Unscrew the drain plug on bottom (switch wires attached). This will empty away water. Screw back up when done then prime the diesel back to fill filter (if there is a lever). If you have no lever then turning the engine over with the starter will prime the filter. Your light should now go out.

The ECU has detected a problem with the emissions system. You will need to retrieve the fault code from the ECU with an OBD2 scan tool. Use that code to narrow down the problem. Remember the code only indicates what part is being effected. It takes skill an knowledge to diagnose the actual cause. Do not just throws parts at the problem. Know exactly what is wrong before buying a part. If you do not have the skill to repair this then spend the money it takes to seek professional help. You will be money ahead of just replacing parts at random.

its the traction control light. more specifically its the traction control malfunction light

Then you need to check the wiring between the computer and the dash. Either the computer has failed, or there is a short in the wire.

The only way to truly turn it off is to fix the problem. To do that, either purchase a code reader or have a third party pull the code for you.

autozone,advance, and some others will check the trouble codes without a charge. This is a starting point on diagnosis.

MPV came a 4 cyl 2.6 liter and a 6 cyl 3.0 liter tom_fdee2002 at yohoo dot com ^^ that's the 89-98 body. The 2000-2001 has a 2.5 litre Duratec DOHC as found in the Contour and the 2002-2006 has the 3 litre version of it as found in Taurus, Tribute and others.

If you have a local Autozone near by go there and ask to pull code then ask to have code cleared. They will do this.

Possible valve cover gaskets are leaking oil onto the plugs and the oil is getting into the cylinder. The oil can also short the plug wire and damage the plug wire causing the check engine light to light.

Replace the oxygen sensors. This should eliminate the 'rotten egg' smell. If the engine has lost power, the converters may need replacing. Though there may well be an electrical problem, a partial collapse of an exhaust system component could restrict airflow enough to cause the engine to 'run rough'. The rough running is an electrical misfire in the engine. The egg smell is the catatytic converter disolving with raw fuel going into it. You will have to check plugs, leads, cap and rotor arm for wear or damage. Dont drive this vehicle because you will have to add the cat converter to your shopping list too. Hope this helps
