What could cause the check engine light to come on in a Toyota Corolla Cross?

When your check engine light comes on, this could be as simple as tightening or replacing your gas cap. Still, the check engine light could still be a warning of a significant problem that could cause serious damage to your engine and come with a hefty and expensive repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady and continuous glow typically means something less serious but a flashing check engine light indicates that your vehicle’s engine is in meaningful trouble and helpful service is required rapidly. If your check engine light is flashing in your Toyota Corolla Cross, we exceptionally recommend not to drive the car and schedule Toyota service today. Below is a list of the most common reasons your check engine light can come on:

  • The battery is low or dead. The battery in your Toyota Corolla Cross is every vital. Without a vehicle battery, your vehicle won’t start, light up the road ahead, 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 genuinely require maintenance. The price of a new one depends on the type of Toyota 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 Toyota Corolla Cross’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 normally caused by invariably neglected maintenance, which is why Nalley Toyota of Roswell offers a free multi-point inspection with every Toyota service. If you have an issue with your catalytic converter and don't get it repaired, your Toyota Corolla Cross 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 expeditiously and your vehicle will be less efficient when it comes to fuel economy. So what happens if I don’t replace your O2 sensor? A broken sensor can not only affect your miles per gallon, but it can cause significant damage to your catalytic converter and your Toyota Corolla Cross's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the explicitly correct combination of air and fuel that enters the cylinders in your engine. A broken O2 sensor can also cause a vehicle to fail an emissions test.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your Toyota Corolla Cross if it’s not installed properly. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound familiar, bring your Corolla Cross to Toyota and have our team of talented certified mechanics guarantee that your aftermarket items were installed accurately and aren't causing any issue. Getting accessories, especially aftermarket parts and accessories, or using OEM parts first place might cost a little bit more but could help you save substantially from having to get poor work and damage caused by poor installation work corrected.
  • One of the most common and frequent cause is that your Toyota Corolla Cross gas cap is loose, damaged or missing. The gas cap for your Toyota Corolla Cross serves numerous purposes. It prevents perilous gas fumes from being released when you aren't driving, it seals the fuel system and helps maintain pressure within the fuel tank. What happens if you have a broken fuel cap? If your gas cap is old or has a ruptured seal, you can lose fuel through evaporation which will result in more trips to the pump and be more pricey. Luckily, to replace a gas cap isn't pricey. If your check engine light turns on expeditiously after you put gas in your Toyota Corolla Cross, first thing you should check is to make sure the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • Your Toyota Corolla Cross has a vacuum leak. Every Toyota Corolla Cross has a vacuum system that performs a wide variety of functions. The vacuum system also helps lower adverse 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, especially if they’re exposed to intense heat or extreme cold.
  • New Spark Plugs or Plug Wires are needed for your Toyota Corolla Cross. The spark plugs are the part of your engine that ignites the air/fuel combination 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 experience a noticeable poor performance and reduced power. In some extreme cases, your engine will have trouble starting or continuing to run. Worn spark plugs and plug wires can cause clogged catalytic converter or damage to ignition coils and O2 sensors, leading to more pricey repairs.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Toyota Corolla Cross is what determines how much fuel is needed 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 Toyota Corolla Cross is having trouble starting, idling rough or has a sudden speedy change in the position of the throttle pedal, this could be a important sign of a broken mass airflow sensor.
