Why Is My Check Engine Light On? Common Causes & Fixes
A check engine light (CEL) can be triggered by various electronic, mechanical, and emissions-related problems. Below are some of the most common reasons your check engine light turns on, along with how our Expert engine diagnostics specialists at Oxenade Motors identify and fix them.
🚨 1. Loose or Faulty Gas Cap
✔ A loose, cracked, or missing gas cap can trigger the check engine light by disrupting the fuel vapor recovery system.
🔧 Fix: Tighten or replace the gas cap to restore the fuel system’s pressure regulation.
🚨 2. Oxygen Sensor (O2 Sensor) Failure
✔ The oxygen sensor measures exhaust gases to regulate the air-fuel mixture. A failing O2 sensor leads to poor fuel efficiency, higher emissions, and rough acceleration.
🔧 Fix: Replace the faulty oxygen sensor for optimal fuel economy and performance.
🚨 3. Catalytic Converter Failure
✔ A failing catalytic converter reduces power, causes engine overheating, emissions test failures, and poor acceleration. You may notice a rotten egg smell in your exhaust.
🔧 Fix: Catalytic converter replacement to meet emissions standards and restore engine efficiency.
🚨 4. Mass Airflow Sensor (MAF Sensor) Failure
✔ The MAF sensor controls air intake and fuel mixture. A failing sensor can cause rough idling, engine hesitation, stalling, and poor fuel economy.
🔧 Fix: Mass airflow sensor cleaning or replacement to restore proper air-fuel balance.
🚨 5. Engine Misfires (Spark Plug or Ignition Coil Failure)
✔ Worn spark plugs or failing ignition coils cause engine misfires, reducing power and increasing fuel consumption.
🔧 Fix: Replace spark plugs, ignition coils, or ignition wires to eliminate misfires and restore performance.
🚨 6. Exhaust Gas Recirculation (EGR) Valve Issues
✔ A faulty EGR valve causes engine knocking, rough idling, poor acceleration, and increased emissions.
🔧 Fix: Clean or replace the EGR valve to ensure proper exhaust gas circulation.
🚨 7. Low Engine Oil or Contaminated Oil
✔ Low or dirty oil leads to engine overheating, knocking sounds, and internal engine wear.
🔧 Fix: Perform an oil change and inspect for leaks to maintain lubrication and performance.
🚨 8. Transmission Issues & Check Engine Light
✔ Transmission faults, such as slipping gears, sensor malfunctions, or torque converter problems, can activate the check engine light.
🔧 Fix: Full transmission diagnostic and fluid replacement for smooth shifting and power delivery.
🚨 9. Vacuum Leaks
✔ A vacuum leak in the intake manifold or hoses can cause rough idling, high RPMs, and fuel efficiency loss.
🔧 Fix: Inspect and replace vacuum lines to restore air intake efficiency.
🚨 10. Throttle Position Sensor (TPS) Failure
✔ A faulty TPS leads to unresponsive throttle, acceleration delay, and stalling.
🔧 Fix: Replace the throttle position sensor and recalibrate the ECU for proper throttle response.
