Check Engine And Cruise Control Light Subaru
A Subaru vehicle is quite popular among car enthusiasts in the United States due to its reliability and durability. However, sometimes even the most dependable vehicle can have issues. One of the most common problems you might experience with your Subaru is the check engine and cruise control light coming on. This issue can cause drivers to be concerned and anxious about their vehicle's overall health. In this article, we will explore this issue in detail and provide you with all the necessary information you need to know to understand and rectify this problem.
What Does It Mean When The Check Engine And Cruise Control Light Comes On?
When the check engine and cruise control light comes on, it indicates that your vehicle's onboard computer has detected a problem with one or more of the systems that controls the engine and emissions. The cruise control light usually comes on only when there's an issue with the engine. This problem is not only limited to Subaru vehicles; it's quite common in most vehicles nowadays.
What Are The Causes Of The Check Engine And Cruise Control Light Coming On?
Several issues can cause the check engine and cruise control light to come on, including:
- Bad Oxygen Sensor: A malfunctioning oxygen sensor can cause these lights to come on. The sensor regulates the air-fuel ratio in the engine, and if it's bad, the engine may run rich or lean.
- Loose Gas Cap: A loose or damaged gas cap can cause the lights to come on. The onboard computer system monitors the pressure in the fuel system, and if it's not right, the system will flag an error.
- Malfunctioning Catalytic Converter: The catalytic converter is responsible for converting harmful exhaust emissions into harmless gases. If it's clogged or malfunctioning, it can cause the lights to come on.
- Failed Mass Airflow Sensor (MAF): The MAF sensor measures the amount of air entering the engine and sends that data to the vehicle's onboard computer. If it fails, it can affect the air-fuel ratio and cause the lights to come on.
- Malfunctioning Ignition Coil: The ignition coil is responsible for creating the spark that ignites the fuel in the engine. If it fails, it can cause misfires and trigger the lights to come on.
- Faulty EGR Valve: The EGR valve recirculates exhaust gases into the engine to reduce emissions. If it's faulty or clogged, it can cause the lights to come on.
- Worn Out Spark Plugs: Spark plugs ignite the fuel in the engine. If they're worn out, it can cause misfires and trigger the lights to come on.
What Should You Do If The Check Engine And Cruise Control Light Comes On?
When these lights come on, it's important to address the issue immediately before it worsens. Here are some steps to take:
- Check Your Gas Cap: Ensure your gas cap is tight and not damaged.
- Check Your Owner's Manual: Your owner's manual will provide you with specific steps to take when these lights come on.
- Get Your Vehicle Diagnosed: Go to a qualified mechanic and have them diagnose the issue. They'll be able to identify the problem and repair it.
- Repair The Problem: Once you've identified the issue, repair it immediately. This will prevent further damage to your vehicle.
- Clear The Codes: Once the problem is resolved, clear the codes with an OBD-II scanner. This will reset the lights and ensure they don't come back on.
Conclusion
If your Subaru's check engine and cruise control lights come on, it's important to address the issue immediately. Several things can cause these lights to come on, including a malfunctioning oxygen sensor, loose gas cap, malfunctioning catalytic converter, failed mass airflow sensor, malfunctioning ignition coil, faulty EGR valve, and worn-out spark plugs. To fix this issue, check your gas cap, check your owner's manual, get your vehicle diagnosed, repair the problem, and clear the codes. Doing this will ensure your vehicle remains running smoothly and efficiently.
