Reasons Why Your Jeep check engine light Flashing

Loose or Missing Gas Cap

The gas cap keeps dirt and other impurities out of the fuel delivery system and stops the gasoline fumes spreading into the atmosphere. But, if you keep driving with a damaged or loose gas cap, fuel vapours may escape.

Malfunctioning oxygen sensor

The oxygen sensorhelps the ECU create the proper air-fuel mixture for combustion by measuring the amount of oxygen left in your exhaust system. However, these sensors may malfunction after extended exposure to hot exhausts gasses.

Misfires, engine stalling, poor acceleration, and an illuminated Check Engine Light can occur from your ECU supplying too much or too little fuel to the combustion chamber due to a malfunctioning oxygen sensor.

The Mass Airflow Sensor is broken

The amount of air that reaches your engine for combustion is influenced by the mass airflow sensor (MAF sensor). However, frequent exposure to air that is full of particles might occasionally harm this sensor, making it misunderstand the airflow. This may result in an active Check Engine Light, harsh idling, and difficulty starting.

Worn Spark Plugs or Wires

When the Spark plugs and their wires deteriorate with use which leads to engine misfiring and the CEL light turning on. Additionally, it may impair your car’s performance to the point where your engine won’t start at all.
