"Service engine soon" light

fairlady_Z · 05-10-2010, 04:18 PM

Mine threw a "service engine soon" light after some car audio electronics work done on it, and this is what I did to clear it:

1. Confirm that accelerator pedal is fully released, turn ignition switch ON (DO NOT depress clutch while you're doing this) and wait 3 seconds.

Repeat #2 procedure quickly five times within 5 seconds:
2. Fully depress then release the accelerator pedal.

3. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 10 seconds until the CEL starts blinking.

4. Fully release the accelerator pedal (while the CEL is still blinking)

5. Wait about 10 seconds.

6. Fully depress the accelerator pedal and keep it down for more than 10 seconds.
7. Fully release the accelerator pedal (The CEL light will continue to blink).

Turn ignition switch to OFF position

Turn ignition switch to ON position and now you can start the car. The CEL light should be gone.

Rep me if this works for you as it did for me.
