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.
On these particular vehicles, it is most common that the O2 sensor is bad. There is only one and it is on the exhaust manifold on the motor side right behind the radiator.
The service engine soon light on an Oldsmobile Cutlass Supreme notifies the driver that it is time to change the oil. It is trigger around the 3,000 mile mark at regular intervals.
unless the battery has been disconnected, a history of previous codes is retained in memory and you will be able to tell why your service engine light was on earlier. disconnecting the battery erases all codes - you would have to wait until service engine light comes on again to read any recent codes. good luck!
It means that you need to get the cars computer scanned to find out what the problem is.
It will, if it causes the fuel mixture to be out of range.
service engine does not have to be on. unless battery has been disconnected, all codes should still be in memory and you will be able to retrieve the codes. I had the same thing happen in my 96 cutlass, it was throwing a code every now and then. The service engine light would come on for a while then go away, however, the car did idle roughly but drove smoothly, after putting the code reader on I found that the cam positioning sensor was faulty. I replaced the sensor the car idled smoothly and the code went away. Hope this is helpfull to anyone.
The service engine light is the same thing as a check engine light.
Probably because you need to check the engine.
Yes, the Service Engine Soon light is the same as the Check Engine light.
The check engine light on a 94 Buick Olds Cutlass is read using an OBDII code reader. It is connected to the port under the dash which interfaced directly with the reader.
The computer stores the codes until it is reset manually. The check engine light does not have to be on to check the codes.
No
