I am not a mechanic, but own a 1999 Sebring. The "Check Engine" comes on for a myriad of reasons. The only way to find the fault is to read the code. This can be done using an engine code scanner, either do-it-yourself or taking the vehicle in to the shop. A third method involves turning the ignition key in a specific sequence which causes the light to flash the numeric code - kind of like a crude Morse Code. For a 1999 Sebring, a common code is the "multiple cylinder misfire." This just says that one or more spark plug(s) failed to fire. If this occurs when changing speeds (entering or exiting a highway, for example) then the EGR valve may be the culprit. I've read that it goes bad on these vehicles. If the vehicle has more than 70k miles, then the fuel filter needs to be replaced, per the maintenance schedule. A clogged fuel filter may also cause piston misfires. Good luck.
FOR FREE YOU CAN TAKE YOUR CAR TO ADVANCED AUTO AND THEY WILL READ THE CODES AND TELL YOU WHAT IT IS CALLING FOR FOR FREE. AND ALSO RESET THE SERVICE ENGINE LIGHT IF YOU WANT THEM TO. BUT THEM YOU WOULD KNOW WHAT THE CAR IS TRYING TO TELL YOU. ALSO YOU CAN TRY TURNING THE CAR TO THE ON AND THEN OFF AND THEN ON ( WITHOUT STARTING THE ENGINE) AND IT WILL FLASH CODES ( BY HOW MANY TIMES THE SERVICE LIGHT FLASHS), JUST JOT DOWN THE NUMBER. IT WILL FLASH ONE OR TWO TIMES AND THEN START FLASHING BETWEEN ONE TO SIX TIMES. COUNT THE FLASH'S IN A ROW AND WRITE IT DOWN AND THAN WAIT AND SEE IF IT FLASH'S AGAIN AND WRITE THAT NUMBER DOWN, IT COULD TAKE A WHILE TO GET THIS DONE. BUT WITH INFORMATION IN HAND YOU CAN EITHER Google AND FIND YOUR ANSWERS OR GO TO ADVANCED AUTO OR A CAR PARTS STORE AND THEY SHOULD BE ABLE TO TELL YOU WHAT IS GOING WRONG WITH YOUR CAR.
Have it checked for codes, That is the same as the check engine light.
Have it checked for codes to know possible causes.
cycle the key three times and count the blinks of the check engine light
Either with a scan tool, or by cycling the key on, off, on, off, on and counting the blinks of the check engine light. Two blinks, pause, one blink would be a 21.
You cycle ignition on, off,on,off,on and count the blinks.
If your check engine light is blinking with the engine running that is indicating a misfire - get your vehicle scanned for any trouble codes to diagnose and then repair the problem
you need to have the check engine/service engine soon fault codes read to determine what the fault is.
It means you have a malfunction in the cars engine. If it blinks stop ASAP!.. You need a scanner to pull the codes to get to what exactly is wrong
-ABS system codes for 1995-98 = code 43 rear right inlet solenoid valve.
The Service Vehicle Soon indicator is usually a light bulb, headlight, or something to do with the vehicle. The Service Engine Soon indicator is anything that could be wrong with the Engine. Some computers can read codes for either, but some computers can only read codes for the Service Engine indicator.
Take it to a service shop and have the trans checked for codes.
