Most car owners have experienced the panic that sets in when the check engine light comes on. It’s a warning that something’s wrong with your vehicle, but it doesn’t give much detail, leaving you wondering what’s happening under the hood. Fortunately, auto diagnostics can identify the problem so it can be fixed quickly and efficiently. We’ll discuss some common causes of a check engine light and how auto diagnostics can help with troubleshooting and repair.
Oxygen Sensor Malfunction
A faulty oxygen sensor is a common cause of a check engine light. The oxygen sensor measures the amount of oxygen in the vehicle’s exhaust to ensure the engine burns fuel efficiently. When this sensor fails, it can cause decreased fuel economy and increased emissions. Auto diagnostics can pinpoint which oxygen sensor is malfunctioning and if it’s reading false data.
Misfiring Engine
When the engine misfires, one or more cylinders aren’t firing correctly, leading to a lack of power and jerky acceleration. The check engine light can come on when the car’s computer detects this issue. Auto diagnostics can show which cylinder is misfiring, allowing the mechanic to replace faulty spark plugs or ignition coils.
Loose Or Damaged Gas Cap
While it may seem trivial, a loose or damaged gas cap can cause the check engine light to turn on. When the gas cap isn’t tightened enough or is damaged, it can allow air to enter the fuel system, disrupting the pressure and triggering the check engine light. Auto diagnostics can determine if this simple fix is needed to turn off the check engine light.
Low Battery Voltage
Modern cars rely heavily on electrical components, and when the battery voltage is low, the check engine light may turn on. If the battery isn’t charging correctly, auto diagnostics can show the source of the issue, whether it’s a faulty alternator or a worn-out battery.
Auto diagnostics has come a long way and can identify the source of a check engine light quickly. The check engine light can alert car owners to potentially serious issues and is not something that should be ignored. The skilled mechanics at your local auto repair shop can use the latest auto diagnostic tools to accurately troubleshoot any issues and get your car back on the road in no time. By paying attention to your vehicle’s warning signals, you can prevent severe damage and save money on repairs in the long run.
