• Your 2021 Subaru WRX has a vacuum leak. Each Subaru WRX has a vacuum system that performs a wide variety of functions. The vacuum system again helps lower harmful emissions by routing the fumes as gasoline evaporates through the engine. If you notice that your RPM is high in idle or randomly surges, a vacuum leak could be the cause. Over time, vacuum hoses can dry out and crack, particularly if they’re exposed to intense heat or extreme cold.
• Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your 2021 Subaru WRX if it’s not installed properly.

Getting accessories, particularly aftermarket parts and accessories, or utilizing OEM parts first place might cost a little bit more but could assist you save considerably from having to get poor work and damage caused by poor installation work corrected.
• Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Subaru WRX is what determines how much fuel is required to run your engine efficiently by measuring the amount of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to certain changes, like altitude. If your Subaru WRX is having trouble starting, idling rough or has a sudden speedy change in the position of the throttle pedal, this could be a vital sign of a faulty mass airflow sensor.
• New Spark Plugs or Plug Wires are required for your 2021 Subaru WRX. The spark plugs are the part of your engine that ignites the air/fuel mixture in the combustion chamber of your vehicle. This explosion is what moves the pistons and makes the engine run smooth. The spark plug wires deliver the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are bad or old, you will undergo a conspicuous poor performance and decreased power. In some extreme cases, your engine will have trouble starting or continuing to run. Worn spark plugs and plug wires can cause obstructed catalytic converter or damage to ignition coils and O2 sensors, leading to more pricey repairs.
• The battery is low or dead. The battery in your 2021 Subaru WRX is each important. Without a vehicle battery, your vehicle won’t start, light up the road in front, play the radio or charge your phone. Today’s vehicle batteries last much longer than they did a few decades ago, and they don't absolutely require maintenance. The price of a new one depends on the type of Subaru you drive, but check our current service coupons and specials.
• Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2021 Subaru WRX’s exhaust system. The catalytic converter's function is to turn the carbon monoxide created by the combustion process into carbon dioxide. A damaged catalytic converter is frequently caused by consistently neglected maintenance, which is why Larry H. Miller Subaru Boise offers a complimentary multi-point inspection with each Subaru service. If you have an issue with your catalytic converter and don't get it repaired, your 2021 Subaru WRX will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your vehicle may run at a higher temperature, too, which can cause other perilous problems from overheating.
• Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, known as the O2 sensor, measures the amount of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns more promptly and your vehicle will be less efficient when it comes to fuel economy. So what hits if I don’t replace your O2 sensor? A faulty sensor can not only affect your miles per gallon, but it can cause serious damage to your catalytic converter and your 2021 Subaru WRX's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the absolutely correct mixture of air and fuel that enters the cylinders in your engine. A faulty O2 sensor can again cause a vehicle to fail an emissions test.

Will the check engine light reset itself?

The check engine light on your 2021 Subaru WRX will usually shut itself off if the issue or code that caused it to turn on is fixed. For instance, if the cause of your check engine light coming on was a loose gas cap, if it's tightened, the light will immediately turn itself off. Still, if your catalytic converter is working accurately, and you did a lot of stop-and-go driving, that may have turned on the check engine light due to the high usage of the converter. In most cases, your 2021 Subaru WRX light will go off after about 20-40 miles. If you drive over that amount and the light is still on, you will need to bring it in to Larry H. Miller Subaru Boise so the light and code can be double-checked and reset.
