Check Engine Light Diagnostics for Asian-Import, Domestic, & European Vehicles in St. Paul

Most drivers have experienced that sinking feeling when they see the check engine light come on. Whether you’re driving to work or on a road trip, it’s always frustrating (and often scary) when your car starts acting up. However, there’s no need to panic just yet. In most cases, the check engine light is simply a sign that something needs to be checked or replaced. It could be something as simple as a loose gas cap, or it could be something more serious like a faulty oxygen sensor. Either way, it’s important to get your car checked out as soon as possible to avoid any further damage. With a little bit of investigation, you should be able to get your car back on the road in no time.

Common Check Engine Light Causes

One of the most frustrating things that can happen when you are driving is to see the check engine light come on. This can be a sign of a minor issue, or it could indicate something more serious. To help you decipher what the check engine light is trying to tell you, here are some of the most common causes:

  • A loose or missing gas cap: This is one of the most common reasons for the check engine light to come on. If your gas cap is not tight, it can cause fuel vapors to escape. The solution is usually as simple as tightening the gas cap.
  • Faulty oxygen sensor: The oxygen sensor monitors the amount of oxygen in the exhaust and adjusts the air-fuel mixture accordingly. If it becomes damaged or contaminated, it will send inaccurate readings to the engine control unit. This can lead to decreased fuel economy and increased emissions.
  • Catalytic converter issues: The catalytic converter helps to reduce pollutants in exhaust fumes. If it becomes clogged or damaged, it will have difficulty doing its job, resulting in an illuminated check engine light.

While these are some of the most common causes of a check engine light, there are other potential issues that could be at play.
