4 Common Check Engine Light Triggers that Can Be Diagnosed by a Mobile Mechanic
Seeing the check engine light come on can be stressful, especially when you’re not sure what the problem is or whether it’s safe to keep driving. Fortunately, mobile mechanics can bring professional diagnostics directly to your location, saving you the time and hassle of going to a repair shop. With the right tools and expertise, a mobile mechanic can quickly determine what triggered the warning and recommend the appropriate repairs. At The Mobile Wrench, we provide mobile check engine light diagnostics in the greater Oklahoma City area. Here are four common check engine light triggers that a mobile mechanic can diagnose and help resolve on-site.
Faulty Oxygen Sensor
The oxygen sensor monitors the level of oxygen in your car’s exhaust and helps adjust the air-fuel mixture for optimal performance. If it fails, your engine may run inefficiently, burn more fuel, and produce higher emissions. A mobile mechanic can use a diagnostic scanner to read the fault code and confirm whether the oxygen sensor is the issue.
Failing Ignition Coil or Spark Plugs
Problems with ignition components can cause the engine to misfire, leading to poor performance, reduced fuel-economy, and a persistent check engine light. A mobile mechanic can use a scan tool to identify misfire codes, check spark plugs and coils, and perform the necessary replacements. Addressing ignition issues early prevents worsening engine issues and helps ensure smooth operation.
Malfunctioning Mass Air Flow Sensor
The mass air flow sensor measures how much air is entering the engine and helps control fuel delivery. If it malfunctions, your car may run rough, hesitate on acceleration, or stall unexpectedly. Resolving mass air flow sensor issues improves engine performance and fuel-efficiency.
Catalytic Converter Efficiency Problems
When the catalytic converter isn’t working efficiently, it can easily trigger a check engine light. A mobile mechanic can evaluate the converter’s performance and determine if a replacement is needed. Signs of a faulty catalytic converter include poor acceleration and a rotten egg smell.
