The check engine light comes on and it’s a total mystery as to WHY for many vehicle owners. The indicator says that there is an issue but does not say where and why. That’s up to us to figure out.
Here are 4 common reasons that light starts glowing:
- Failing oxygen sensor — The O2 sensors handle emission checks and check gasses leaving the engine. Performance is affected and this should be addressed.
- Wiring and spark plug issues — The symptoms might be pinging noises, rough idling, and power surges/losses. This should be examined a.s.a.p.
- Airflow sensor problems — Mass airflow sensors check the air coming from the engine and assess fuel needs, too. Engine performance and fuel efficiency can suffer when this is out of balance, so it should be checked.
- Battery or charging system glitches — The computer systems in modern vehicles monitor voltage in batteries and electrical systems. If something is off-kilter the check engine light comes on. Get that section checked by a mechanic if you suspect it’s the issue.
While that passive-aggressive vagueness of the check engine light can be frustrating, it is there to help us keep our vehicle running smoothly and safely. Get in touch with Parker Towing Service for more information. We offer a 24/7 Tow Truck service and you can call us in an emergency.
