What Causes the Check Engine Light to Come On?

Your check engine light may indicate:

Faulty oxygen sensor

A common cause that affects fuel economy and emissions.

Loose or damaged gas cap

Simple issue, but easy to overlook.

Misfires or ignition coil problems

Often causes rough idling or shaking.

Catalytic converter problems

Can trigger reduced engine performance.

Mass airflow (MAF) sensor issues

Impacts engine power and acceleration.

Spark plug or wire failures

Leads to poor starting and engine hesitation.

Vacuum leaks

Can cause high idle or rough running.

Fuel system problems

Clogged injectors, failing pumps, or dirty filters.

Even a minor issue can turn into major damage if ignored—especially if the light is flashing.

Why You Shouldn’t Ignore a Check Engine Light

Reduced fuel efficiency

Faulty sensors can waste gas quickly.

Engine misfires can damage your catalytic converter

This can turn a small repair into a major expense.

Potential breakdown risk

Minor issues can worsen fast.

Emissions test failure

Oregon DEQ will not pass a vehicle with an active engine code.

If the check engine light is blinking, pull over and call us immediately—this signals an urgent problem.

If you notice any of the following, your vehicle likely needs diagnostics:

  • Rough idle
  • Loss of power
  • Hesitation or stalling
  • Shaking or vibrations
  • Poor fuel economy
  • Strong fuel smell
