Check Engine Light Diagnosis – Fast, Accurate, and Reliable Service 

Is Your Check Engine Light On? Don’t Ignore It! 

Nothing causes more stress than seeing the Check Engine Light (CEL) suddenly appear on your dashboard. It could be something minor like a loose gas cap or something serious like an engine misfire. The key is not to ignore it—driving with an active check engine light can lead to costly repairs if left unchecked. 

At JK Automotive, we provide professional Check Engine Light diagnostics to quickly identify the issue and get you back on the road with confidence. Our advanced diagnostic tools allow us to pinpoint the exact problem so you don’t waste time or money on unnecessary repairs. 

Common Reasons for a Check Engine Light 

✅ Loose or Faulty Gas Cap – One of the most common causes. A loose cap can trigger the light due to evaporative emissions leaks. 

✅ Oxygen Sensor Failure – A faulty O2 sensor affects fuel efficiency and emissions, often leading to poor gas mileage. 

✅ Mass Airflow Sensor (MAF) Issues – The MAF sensor controls fuel-air mixture; if faulty, it can reduce performance and fuel economy. 

✅ Faulty Spark Plugs or Ignition Coils – Worn-out plugs and coils can cause misfires, rough idling, and reduced power. 

✅ Catalytic Converter Problems – A failing catalytic converter affects emissions and can reduce engine performance. 

✅ EGR Valve or PCV Valve Issues – These emissions control components can get clogged or fail, triggering a CEL. 

✅ Transmission Issues – Some transmission faults can trigger the light, affecting shifting and acceleration. 

✅ Battery & Charging System Problems – Low voltage or alternator issues can cause electrical system faults.
