Meridian Check Engine Light

If your car’s check engine light came on while you were driving, would you know what to do? If you answered “no,” you have plenty of company. In this article, we’ll go over the reasons your vehicle’s check engine light (CEL) may come on and explain the best actions to take. If you live in Meridian, check engine light service is just minutes away when you visit Edmark Toyota in Nampa.

In most cases, the check engine light isn’t an emergency, so don’t panic. It may even be caused by something trivial like a defective gas cap. But there are instances when the check engine light is more serious. When the check engine light comes on, bring your Toyota to the Edmark Toyota Service Center for CEL testing & diagnosis near Meridian.

The check engine light can either be steady or flashing. A steady light indicates a situation that needs to be checked and fixed, while a flashing light is alerting you to a serious problem that must be taken care of immediately.

Flashing Check Engine Light
A flashing check engine light usually means the ignition system is misfiring. This causes unburned fuel to be dumped directly into the exhaust system, a condition that will damage the catalytic converter. If left uncorrected, you’ll be faced with an expensive repair. If a flashing check engine light comes on, the best course of action is to pull over, shut off the ignition, and call for roadside assistance.

Steady Check Engine Light
A steady light is alerting you to a problem that isn’t urgent but needs attention. If you see a steady check engine light, call the Edmark Toyota Service Center and make a service appointment. A steady check engine light can be caused by one of the following conditions:

    • Loose, Missing or Damaged Gas Cap
      A problem with the gas cap is the easiest issue to fix. If your car’s gas cap is loose, missing or damaged, gas fumes can escape from the fuel system. When the gas evaporates, you’ll get lower fuel economy. If the gas cap is loose, tighten it. If it’s missing or damaged, replace it.
    • Bad Catalytic Converter
      Your Toyota’s catalytic converter converts carbon monoxide into carbon dioxide. If the catalytic converter is damaged, the vehicle will experience a drop in fuel economy, and the engine will lose some power. If you live in an area with mandatory emissions testing, your vehicle will fail the test.
    • Faulty Oxygen Sensor
      The oxygen (O2) sensor measures the unburned oxygen in the vehicle’s exhaust system. When the sensor is bad, the engine will burn more fuel. Your Toyota will lose fuel economy. A faulty O2 sensor left unrepaired will damage the catalytic converter and the spark plugs.
    • Broken Mass Airflow Sensor
      Your Toyota’s mass airflow sensor measures the engine’s air inflow and controls the amount of fuel needed to run the engine. If the mass airflow sensor is defective, it can damage the catalytic converter, spark plugs and O2 sensor. You’ll experience reduced performance and lower fuel economy.
    • Faulty Spark Plugs
      Bad spark plugs and wires can damage the catalytic converter, O2 sensors and ignition coils. You’ll experience a hit in performance and reduced fuel economy.
