Subaru Check Engine Light Diagnostics and Repair

Subaru Check Engine Light Diagnostics And Repairs

Check engine light illuminating is among the greatest trepidations of any Subaru owner. At Diablo Auto Specialists in Walnut Creek we can take the dread out of the check engine light repair. Essentially the check engine light tells you that your Subaru’s onboard computer has detected a malfunction that needs to be resolved. Because the check engine light coming on can mean different things, it’s important to drive to an auto repair shop for Subaru check engine diagnostic and repair. 

What does your check engine light mean?

Here are some things your Subaru vehicle may be telling you when the check engine light comes on. 

• Problem with the gas cap

When your check engine light illuminates, one of the first things to check is your vehicle’s gas cap. It could be that your gas cap is loose or damaged, and this may lead to decreased efficiency. If it’s loose, all you have to do is tighten the gas cap otherwise. But if it’s damaged, it will have to be replaced.

• Oxygen sensor malfunction 

Another reason the check engine light illuminates is when the oxygen sensor is failing. This component measures the amount of unburned oxygen in your Subaru’s exhaust. When the sensor malfunctions, it will trigger the check engine light.

• Mass airflow sensor failure 

Your Subaru comes with a mass airflow sensor that measures the air coming into the engine to ensure it mixes with the right amount of gasoline for proper functioning. When this car component fails, your car’s check engine light will alert you of the imbalance. 

• Bad catalytic converter 

The catalytic converter is the crucial part of the emission system. When if fails (fortunately it’s a rare event), the check engine light will be illuminated. 

• Faulty spark plugs 

Spark plugs are that component of your vehicle that ignites a mixture of fuel and air to create combustion and power your engine’s cylinders. Faulty or worn-out sparks can cause engine misfire and the check engine light to come on.  

Given that there are literally hundreds of conditions that can cause the check engine light to come “on”, we recommend that you bring your vehicle to a professional mechanic. Driving around with the check engine light “on” can results in expensive damage to your Subaru.So if the check engine light is illuminated, bring your Subaru to Diablo Auto Specialists. Our technicians, certified by the National Institute for Automotive Service Excellence (ASE), are highly skilled at check engine light diagnostics and are equipped with the latest digital diagnostic tools. Call the shop to make an appointment.
