The Check Engine light might not be pleasant news, but it’s a vital alert for potential issues in your engine, exhaust, or battery. It’s tied to the OBD system, which monitors your emissions and activates the light for various reasons, from a loose fuel cap to a failing catalytic converter.
Don’t ignore it. Monty’s Automotive technicians are experts in OBD II diagnostics and can interpret your Check Engine light’s message. We’ll explain what’s happening with your engine or emissions system and provide a detailed estimate before any necessary repairs.
why is my check engine light on?
The Check Engine light often signals the need to replace parts like the oxygen sensor, catalytic converter, mass airflow sensor, or spark plugs and wires. It can also point to a loose gas cap, vacuum leak, exhaust gas recirculation valve issue, a dead battery, or problems with an aftermarket alarm.
If your Check Engine light is solid, it’s best to have it checked as soon as possible. A flashing light indicates an urgent issue—head to your nearest Monty’s location immediately.
Wondering if it’s normal for the light to flash briefly at startup? Yes, all dash lights turn on momentarily when your car starts to check the system. It also shows any burnt-out bulbs to your technician.
What do I do if the check engine light is on?
How you respond to a Check Engine light depends on the situation and your vehicle:
- Quick tip: Check your fuel cap. Tightening it could turn off the light and get you back on the road.
- Flashing light: Pull over immediately and call for a tow. Driving could damage your engine or catalytic converter.
- Flashing light turned solid: Get your car serviced right away, as the issue is still serious.
- Steady light: Schedule a mechanic visit as soon as possible; multiple issues could trigger the light.
- Light stays on after service: It’s safe to wait a few days to see if it turns off. If not, contact Monty’s to ensure the issue is resolved.
