Hi, thanks for choosing JA

The engine light is activated by the vehicle PCM. I would not recommend attempting to disable the service light from the vehicle.
The best way to turn off the light without risking serious damage to the vehicle are:

  1. Removing the bulb from the cluster/ instrument panel.
  2. Fixing the problem.
  3. Disconnecting the battery (this will only temporarily disable the light)
  4. Using a scan tool to reset the light
Can I assist you in repairing the vehicle?
Some states require a functional engine warning light to pass inspection standards.

Expert:  Tim West replied 8 years ago.
You replaced the converter in this vehicle already?

Either way I know what you are trying to accomplish.

I know a trick, but it only has about a 50% success rate.
I have cleared many cat codes this way. Thats how my girlfriend passed her inspection.
Are you interested?
(won't make the cat function like new or anything but has been known to shut the light off for months even years. The cost... about 4.00$
