Check Engine And Cruise Control Light Subaru Wrx
Subaru WRX is an amazing car that comes with advanced features and cutting-edge technology. It offers a thrilling driving experience and is known for its excellent speed, agility, and handling. However, like all other cars, the Subaru WRX may show some warning signs and issues that need attention. One such issue is the Check Engine and Cruise Control Light that may turn on simultaneously.
What Is Check Engine Light And Cruise Control Light?
Check Engine Light (CEL) is a warning light that appears on the dashboard of a car. CEL indicates that there is a problem with the car's engine or emission system. When this light turns on, it means that the car's onboard computer system (ECU) has detected a fault or error in the system. It could be anything from a minor issue to a major problem that needs immediate attention.
Cruise Control Light, on the other hand, is a light that indicates that the car's cruise control system is active. When this light turns on, it means that the driver has engaged the cruise control system, and the car is maintaining a steady speed without the need for the driver to step on the gas pedal.
When the Check Engine Light and Cruise Control Light turn on simultaneously, it means that there is a problem with the car's engine or emission system, and the cruise control system has been disabled as a precautionary measure.
Common Causes Of Check Engine And Cruise Control Light On Subaru WRX
There could be many reasons why the Check Engine and Cruise Control Light turn on in a Subaru WRX. Some of the common causes include:
Faulty Oxygen (O2) Sensor
The O2 sensor is responsible for measuring the amount of oxygen in the exhaust system. When the sensor fails or malfunctions, it can cause the Check Engine Light to turn on. As a result, the Cruise Control Light may turn on too since the cruise control system relies on the O2 sensor's data.
Loose Fuel Cap
A loose fuel cap can cause the Check Engine Light to turn on. When the cap is loose, it allows air to enter the fuel system, which can interfere with the fuel-to-air ratio. This can cause the engine to run poorly, and as a result, the CEL and Cruise Control Light may turn on simultaneously.
Faulty Mass Air Flow (MAF) Sensor
The MAF sensor measures the amount of air entering the engine. When the sensor fails or malfunctions, it can cause the engine to run poorly, and as a result, the Check Engine Light may turn on. This can also cause the Cruise Control system to turn off as a precautionary measure.
Faulty Catalytic Converter
The catalytic converter is responsible for converting harmful emissions into less harmful ones. When the converter fails or malfunctions, it can cause the Check Engine Light to turn on. In this case, the Cruise Control Light may also turn on since the cruise control system relies on the catalytic converter's data.
What To Do When Check Engine And Cruise Control Light Turn On?
If the Check Engine and Cruise Control Light turn on in your Subaru WRX, it is important to take immediate action. Here's what you should do:
Check The Fuel Cap
Check whether the fuel cap is loose or not. If it is loose, tighten it properly and see if the lights turn off after a few drives.
Bring Your Car To A Mechanic
The best thing to do is to bring your car to a mechanic as soon as possible. The mechanic will use a diagnostic tool to determine the exact cause of the problem and provide the necessary repairs.
Don't Ignore The Lights
Avoid ignoring the Check Engine and Cruise Control Light, even if your car seems to be running fine. These lights indicate that there is a problem with your car, and driving with the lights on can cause further damage to the engine or emission system.
Conclusion
The Check Engine and Cruise Control Light turning on simultaneously in a Subaru WRX can be a cause for concern. It indicates that there is a problem with the car's engine or emission system, and the cruise control system has been disabled as a precautionary measure. Common causes include a faulty oxygen sensor, loose fuel cap, faulty MAF sensor, and faulty catalytic converter. If the lights turn on, it is important to take immediate action, such as checking the fuel cap or bringing your car to a mechanic for a proper diagnosis and repair. Ignoring the lights can cause further damage and compromise your safety.
