What Does The Ford F-150 Check Engine Light Mean?

Posted at Wed, Oct 30, 2019 12:00 AM

You wake up, take care of your morning duties, get dressed to go to work, get into your vehicle, turn the ignition, and then you see it: the dreaded Check Engine Light (CEL) looking back at you from the gauge cluster. Your vehicle seems to be running fine, with no signs of failing engine functions, but the CEL tells you otherwise. This is always a frustrating and often beguiling ordeal, and the professionals at Marshal Mize Ford can help you decipher what’s behind the CEL. There are many reasons — both big and small — that the CEL might be on, but there is never a reason to neglect it. Getting a CEL looked at or taken care of is particularly important when it comes to your Ford F-150 truck model. While the fabled F-150 trucks have a reputation for being durable and dependable, sometimes they need a little more attention beyond routine maintenance and oil changes. Your Chattanooga Ford destination wants you to become keenly aware of some of the reasons behind the CEL, and welcome you to contact our service department if you have further questions or want to schedule an appointment.

The service experts at Marshal Mize Ford are ready to take on any challenges related to the Check Engine Light on your Ford F-150 pickup truck model, but would like to discuss some of the reasons the light is on in the first place. While this is not an exhaustive list, it remains a good place to start when trying to figure out what kind of servicing your F-150 truck requires.

  • Oxygen Sensor: The Oxygen Sensor, or more commonly referred to as the O2 Sensor, regulates the amount of uncombusted oxygen remaining in the exhaust system. Too much or too little oxygen in the lines can cause poor fuel economy and even reduce the overall performance of your vehicle.
  • Gas Cap: Ever filled up a gas station and forgot to put the gas cap back on, or didn’t tighten it all the way. This is a simple and sometimes overlooked problem that can be solved with a simple action.
  • Catalytic Converter: The buffer between proper and improper emissions. A worn catalytic converter can result in a failed emissions test and the dreaded loss of performance.
  • Spark Plugs: A small but critical component of the internal combustion system, faulty spark plugs can affect everything from fuel mileage to your Ford F-150 pickup not even starting.
  • Mass Airflow Sensor: This part controls the amount of air being funneled into the engine, and poor readings from the sensor can lead to total shutdown of the engine.

These are just a handful of events that can trigger the Check Engine Light on your Ford F-150 truck, and your local Ford service center is your go-to destination to take care of any and all service needs. Call Marshal Mize Ford today or schedule your appointment to take care of Check Engine Light issues for your F-150 or any other Ford car, truck, crossover, or SUV model!
