Asked by Jan 11, 2016 at 03:33 PM about the 2003 Hyundai Tiburon GT V6

Question type: Maintenance & Repair

I've had my mechanic try to solve this as well as smog shop. My 2003 tiburon's check engine light won't come back on for smog to show a fail for a CA claim. I've driven car "cycles" and driven car for 140 miles after last reset, still no light and it wont pass smog. Light does work when I turn on ignition...

If the light comes on steady with the ignition in the run position but the engine is off, the bulb and wiring are good. However if the light cannot be commanded on the PCM is bad. HTH. -Jim
