What is service engine light code 12 mean



READING CODES USING MIL (CHECK ENGINE) LAMP

Be advised that the MIL or CHECK ENGINE light can only perform a limited number of functions and it is a good idea to have the system checked with a scan tool to double check the circuit function.

  1. Within a period of 5 seconds, cycle the ignition key ON - OFF - ON - OFF - ON .
  2. Count the number of times the MIL (check engine lamp) on the instrument panel flashes on and off.

The number of flashes represents the trouble code. There is a short pause between the flashes representing the 1st and 2nd digits of the code. Longer pauses are used to separate individual 2-digit trouble codes.
An example of a flashed DTC is as follows:


Lamp flashes 4 times, pauses, then flashes 6 more times. This denotes a DTC number 46. Lamp flashes 5 times, pauses, then flashes 5 more times. This indicates a DTC number 55. DTC 55 will always be the last code to be displayed.

Where do I plug in my car to find out engine codes on my 93 dodge shadow


You don't need to, just cycle key, on (not start) off,on,off,on and leave in on position and count flashes of check engine light.
Will be a 2 digit number with pause in between. For example: 3 flashes, pause, 3 more, is code 33. 1 flash, pause, 2 flashes, is code 12. When you get 5 flashes, pause, 5 more, that's 55 which means end of message.

Engine code


12 and 55. The 55 means end of code session, the 12 means no distributor reference. Both of these codes are normal with the engine not running, so do not go out and purchase a dstributor. Is there another problem with the vehicle, or did you just want to know the codes? Comment back to continue,thanks.

Have you done the cycle key test to see if any trouble codes come up ? Turn key to on (not start) then off, then on, then off, then on, and leave in on position. Have a pen and paper ready to retrieve code numbers. "Check engine" light will flash . You'll get a number of flashes if any codes, and a pause in between each number. For example: flash,flash,pause,flash,flash will be code 22.
3 flashes, pause , then 3 more flashes, is code 33 etc. It will always be 2 digit number, with a pause in between. When you get 5 flashes,pause and 5 more, that is code 55 which means end of message.(or end of codes). Get back to me with those codes and lets go from there, as it will make it much easier to pinpoint problem, if codes are there, and much cheaper and quicker in long run.

Sounds like you need to check for a vacuum leak.(hissing noise) Also try this,: Cycle key, on, off, on, off, on, and leave on (not start) & count "check engine" light flashes. Always a number, a pause, then another number. For example: 2 flashes,pause, then 2 more is code 22. 3 flashes, pause 5 more, is code 35 etc. When you get 5 flashes, pause, then 5 more, that's code 55 which means end of message. Try that and lets see if any codes come up & go from there. Get back to us with what you find.

99 Saturn SC1 ''Service engine soon'' light is on.


Did you get the code that triggered the SEL? If you know that, it will be easier to diagnose your problem. You can do it without a tool on the old saturns. Just need a paperclip. :

Use a paper clip to jumper Terminal A and B of the ALDL *Assembly Line Diagnostic Link* which is above your left knee.
Terminal A is an interal ground and is the top right terminal in the connector. Terminal B is directly adjacent and to the left of Terminal A.

Turn the ignition to ON.

All codes are 2 digits between 11 and 99. Codes are displayed on the SES light by flashing the light with short and long pauses to distinguish digits of one code from digits of another. The short pause is used between digits of the same code, long pauses are between codes. Also, each code is flashed three times before going to the next code.

For example, the sequence of code 12 will be: flash, pause, flash-flash, long pause, then repeat 2 times. If Code 12 is not displayed, the self-diagnostic pogram i snot functioning properly.

If only Code 12 is displayed, no system malfunctions have been stored.

Any existing system fault codes are displayed in order from low to high, except for Code 11.

On vehicles with an automatic transaxle and on which exist stored transaxle codes, Code 11 will be displayed last, then the SHIFT TO D2 light will begin flashing transaxle codes of flags.

When all engine codes have been displayed, Code 12 will flash again.

CHECK ENGINE LIGHT CAME ON WHILE DRIVING, CAR DIED , FOUND OIL IN 3 OF THE PLUGS REPLACED VALVE COVER GASKET AND RINGS AND PLUGS TRIED 2 START BUT NO SPARK, DID CODE RECOVERY W/ IGNITION KEY. THE BEEPS...


What year is your car and what engine? That makes a lot of difference. What the pulses should indicate is a code 12 is stored (code 55 is usually an "all clear" code, meaning that the ECU is done reading out the codes that are stored). If you got only a 55, it would mean you have no codes. 1255 means that 12 is the only code you have stored.
