Check Engine Light - Diagnostics in Covina, CA at TL Motors Inc.

Check Engine Light, it’s a scenario that’s befallen on drivers everywhere: They turn on the car and start to fiddle with the radio then suddenly glance down at the dash and notice — the check engine light is still on!

What does this mean? Well, for starters probably a pretty annoying day. If your check engine light is illuminated, it’s best to take it in for diagnostic testing, which can feel like a hassle. Because while the lights vary in appearance from vehicle to vehicle, all have the same basic meaning: There’s a problem with the car’s emissions system. The on-board diagnostics system and engine control unit are in charge of monitoring a bunch of different parameters, and if they get a reading that’s a little out of whack, up pops the check engine light.

The list of things that can trigger the check engine light is pretty lengthy. For example, anything from a loose gas cap to a faulty fuel injector can be to blame. Some other potential culprits that can cause that malevolent glow include:

  • A wet engine
  • A blown gasket head
  • Faulty oxygen sensors
  • Worn-out spark plugs or spark plug wires
  • Loose or cracked hoses and manifolds
  • Sticky exhaust gas recirculation valves
  • Pinched or deteriorated fuel injector O-rings

A few of the above items are inexpensive to fix. While others are more expensive, it’s still important to get them taken care of.

So first thing first: Check to make sure your gas cap is on and give it a few more clicks to tighten it up. If that doesn’t work, head to TL Motors — Our professional have all the latest diagnostic equipment to diagnose the problem and get you one your way to turning of that anoying light. Even though the car could be driving just fine, you may be wasting fuel, putting out lots of pollution and damaging the engine.
