Why is My Check Engine Light On?
An illuminated check engine light indicates that your vehicle has a problem. Usually, the ECU (Engine Control Unit) doesn’t know the exact cause of the issue, or whether it is a minor or major problem, so this catch-all warning light comes on.
Ignoring the light can be incredibly unsafe and could lead to costly repairs later down the line, so it’s always best to seek a timely solution when yours comes on.
6 Issues That Cause the Check Engine Light to Come On
Your car’s check engine light could be on if any of the following issues are present:
- A loose or faulty petrol cap
- A faulty oxygen sensor
- An issue with the fuel injectors
- A catalytic converter problem
- Mass airflow sensor issues
- A spark plug or ignition coil problem
This is NOT an exhaustive list by any means – any issue with your car that isn’t covered by another warning light could be present, so getting to the root of the problem quickly is a must.
Does the Light Come on in Different Colours? How Serious is Each One?
Your engine management light can show as steady amber, flashing amber or steady red, depending on the severity of the issue.
A flashing amber or steady red engine light means that your vehicle has a serious issue which needs to be addressed right away.
In the case of a red engine management light, you should stop driving immediately and call your recovery provider as the car may not be safe to drive.
Even neglecting a steady amber light can cause long-term damage to your vehicle and may lead to an MOT failure – so don’t delay booking an appointment to solve the problem at our garage in Otterbourne.
