Toyota Runx 2004 1.5l engine Japanese model is giving me trouble with this code. Sometimes when i start the engine or maybe when i am driving. Check engine light will come on with a code C1249. Help, already changed the brake light switch to attempt to fix the problem but it didn't work. My brake lights works just fine but i don't like seeing that check engine light that comes and goes.
