Check Engine Light
Your check engine light means the computer saw something outside its normal range. Sometimes it’s simple, like a gas cap. Sometimes it’s a misfire, an emissions fault, or a sensor problem that gets worse if you wait.
Symptoms
- Solid check engine light, and the car still drives normally
- Flashing check engine light (often a misfire)
- Rough idle, hesitation, or less power
- Worse fuel economy, or a new smell from the exhaust
- Light came on after filling up or after a recent repair
Can I keep driving with the check engine light on?
If the light is steady and the car feels normal, you can usually drive carefully to the shop soon. Don’t leave it for weeks.
If the light is flashing, that often means an active misfire that can damage the catalytic converter. Drive gently and get it checked as soon as you can.
If the light is on with hard shaking, overheating, or an oil-pressure warning, stop driving and call us.
Common causes
- Loose or failed gas cap (evaporative emissions)
- Oxygen sensor or catalytic converter efficiency codes
- Ignition misfire — coils, plugs, or injectors
- Mass airflow problems or intake leaks
- Transmission or another system that asked for a warning
What happens next when you bring it in?
- 1 Call or text and tell us if the light is steady or flashing, and what else you’ve noticed.
- 2 We scan the car, check live data, and find the fault behind the code before we talk about parts.
- 3 We’ll show you what we found and explain what needs attention now and what can wait.
