A 1993 will have the old OBD I system in it. You will be able to get the check engine light to flash by making a jumper and inserting it into the A and B terminal on the ALDL connector under the dash. The ALDL is the connector that you would plug a scan tool into.check engine light on - aaec4d88-da23-44e1-93a1-e4ce39abfe63.gif
You can see by the image what 2 contacts you are wanting to connect with your jumper wire. When you turn your key to the "ON" position your check engine light will flash a series of flashes and pauses. These are your codes, you will need to get a code book to decode what the problem is.

How do you turn off engine light on a 2009 Mercury Marquis


The Check Engine light must be reset using an OBD-II code reader. Dealers have them as do repair shops. Places like AutoZone will read the codes for you, but normally will not reset the Check Engine light due to possible liability issues. You can purchase a code reader at these places to do this yourself. Make sure you get one that can read and reset the engine light. The very cheap ones cannot reset the Check Engine light.

Check engine light on with the TPS code. replaced TPS and pig tail and it checked out OK with volt meter. The light still comes back on with the TPS code


Check engine light comes on and off, these are indication that there is some error code stored in your vehicles ECM. The engine module computer needs to be scanned. These will give the code and as per the error code the further problem can be detected and confirmed. The engine light indicator blinks or remains steady on dash when engine computer noticed any problem with any engine electrically operated components.


For more help, I suggest you to refer the help links provided below. These will let you know more about which areas to look, check, when there is engine light coming up on dash panel.

How to reset check engine light?


Go to your local O'Rielly's or Autozone. They will tell you the code and reset it for free. Otherwise take the negative battery cable loose for about 10 min. This will clear the ECM, but you won't know what tripped the light! Best Wishes, TJ

Check engine light on..engine coolant was low..filled it..light still on with no obvious problems


Your check engine light must be reset. Many auto parts stores will hook up and check your codes for free. This will tell you why your check engine light came on. After receiving the code information they will often allow you to reset your check engine light with their machine. Hope this was helpful.

How to reset the check engine on a 208 chevy


Just disconnect the battery (negative terminal) and turn the headlight switch on for about 15 minutes. This should reset the PCM. Otherwise go to Advance and have them hookup the code reader and reset the codes. Thanks
