Common Symptoms

If your Subaru’s check engine light is on and the cruise control is flashing, this could be a sign of a serious issue. The flashing cruise control light indicates disabled cruise control, a potential indication of engine or transmission problems.

It’s important to have your vehicle inspected by a professional to address the underlying issue.

Check Engine Light Illuminated

One of the common symptoms that Subaru owners may encounter is an illuminated check engine light. This warning indicator is designed to alert drivers that there is a problem with the vehicle’s engine or emissions system. When the check engine light comes on, it is important to address the issue promptly to prevent any potential damage to the engine.

There can be various reasons why the check engine light may illuminate in a Subaru.

Causes

When the check engine light on your Subaru is flashing and the cruise control light is also blinking, it typically indicates that the cruise control has been disabled and there may be a problem with the vehicle’s dynamic stability control.

It is important to have your vehicle examined by a professional to diagnose and address the issue.

There are several possible causes for the check engine light and cruise control flashing in your Subaru. Understanding these causes can help you determine the necessary steps for troubleshooting and resolving the issue.

Engine Misfire

An engine misfire occurs when there is a problem with the combustion process in one or more cylinders of the engine. This can be caused by issues such as faulty ignition coils, spark plugs, or fuel injectors. When the engine misfires, it can trigger the check engine light and cause the cruise control to flash. It is important to address engine misfires promptly to prevent further damage to the engine.

Faulty Sensors

Subarus are equipped with various sensors that monitor the performance of different components in the vehicle. If any of these sensors malfunction or provide inaccurate readings, it can trigger the check engine light and cause the cruise control to flash. Common sensor issues include a faulty oxygen sensor, mass airflow sensor, or catalytic converter temperature sensor. Proper diagnosis and replacement of faulty sensors can resolve the issue.

Electrical Issues

Electrical issues can also be responsible for the check engine light and cruise control flashing in your Subaru. Problems with the vehicle’s electrical system, such as a loose or damaged wiring harness, can disrupt the communication between different modules and sensors, leading to malfunctioning cruise control and triggering the check engine light. Professional inspection and repair of the electrical system may be required to resolve this problem.

In conclusion, the check engine light and cruise control flashing in your Subaru can indicate various underlying issues. Engine misfires, faulty sensors, and electrical issues are common causes. Prompt diagnosis and appropriate repairs are necessary to address the problem and ensure the proper functioning of your vehicle.

Troubleshooting Steps

When your check engine light and cruise control are flashing in your Subaru, it can be a cause for concern. However, with some simple troubleshooting steps, you can identify and potentially resolve the issue. These troubleshooting steps can help you diagnose the problem and decide whether a visit to a professional mechanic is necessary.

Check Gas Cap

A common reason for the check engine light and cruise control flashing in a Subaru is a loose or faulty gas cap. Ensure the gas cap is securely fastened, and the seal is in good condition to prevent any air leaks. A damaged or improperly sealed gas cap can trigger a warning light on your dashboard, causing the cruise control to deactivate.

Diagnostic Trouble Code (dtc) Check

To pinpoint the issue, perform a diagnostic trouble code (DTC) check using an OBD-II scanner. This device can retrieve specific codes from your vehicle’s onboard computer, indicating the source of the problem. Once you have the DTC, refer to your vehicle’s manual or seek professional assistance to interpret and address the issue.

Inspect Electrical Connections

Inspect the electrical connections related to the cruise control and engine systems. Loose or corroded connections can disrupt the communication between components, causing the warning lights to illuminate. Check for any visible damage or abnormality in the wiring and connectors, and address any issues found to ensure proper functionality.
