There are two sets of leads under the dash, steering column side, one set black, one set green. connect black leads ignition on, but do not start the engine! this will allow the engine management light to blink out the code (long blink = 10 short blink =1)
connect green leads, drive car for 1 min at over 10 mph, stop and hold car revs at 2000rpm
you will then get four long blinks from engine light, disconnect leads and problem is cleared from memory!
mine turned out to be a sticky waste gate!
oh and if engine light is on very often, car will not rev past 4200 rpm as it goes into defense mode if it senses a problem!!
Try your local auto part store. The ones near me will read the codes for free. --Ken
Are you asking how to clear engine trouble codes? You'll need a code scanner with a reset/erase feature.
pretty much instantly. As soon as the codes are cleared the check engine light goes off and vice versa, unless there still is trouble. In this case the codes won't clear until the trouble is repaired.
To clear parking assist trouble codes on a 2003 Lincoln Town Car, you can use an OBD-II scanner to read and erase the codes. Connect the scanner to the vehicle's OBD-II port, typically located under the dashboard. Follow the scanner's instructions to clear the trouble codes. Alternatively, you can disconnect the vehicle's battery for about 15 minutes to reset the system, but this may also reset other vehicle settings.
To clear codes after installing a crank sensor on a 1996 Acura 3.2, you can use an OBD-II scanner to read and clear the diagnostic trouble codes (DTCs). Simply connect the scanner to the vehicle's OBD-II port, follow the prompts to access the trouble codes, and select the option to clear them. Alternatively, you can disconnect the vehicle's battery for about 10-15 minutes, then reconnect it, which will also reset the codes. Be sure to check that the new crank sensor is functioning correctly before clearing the codes.
To reset the check engine light in a 2003 Subaru Forester, you can disconnect the negative battery terminal for about 15 minutes. This will clear the vehicle's onboard computer and potentially turn off the light. Alternatively, you can use an OBD-II scanner to clear the trouble codes that triggered the light. However, it's important to address the underlying issue that caused the light to come on to prevent it from reappearing.
At home you can disconnect your neg. battery terminal for a few minutes then reconnect. Also, to find the codes (what kind of problem you have) go to Auto Zone and they will run a check for free (they say they won't clear the codes for you though).
After performing checking procedures on any OBD-II components, clear the PCM of all trouble codes by disconnecting the negative cable from the remote battery terminal for at least ten seconds.
Borrow, rent or buy a good quality OBD2 code scanner. The good ones let you clear the codes. Any codes that WON'T clear are usually caused by a failed component that needs to be replaced.
Disconnect the Battery. Negative prefered. Wait a couple minutes and reconnect. This will clear codes on 1994 and older. If the light comes back on, check the trouble codes and a repair may be needed.
