When there's something wrong with your Toyota Celica GT, and it has something to do with one of the sensors on the car, then your vehicle's check-engine light will come on. If you ignore this problem, you could seriously damage the GTs engine, fuel, or exhaust system. This could mean anything from a decrease in fuel economy to catastrophic failure of the catalytic converter if the problem is serious enough. Troubleshooting the check-engine light involves the use of an OBD--on-board diagnostic--scan tool, which is available at most auto-parts stores.
