Remote start is a convenient feature that allows you to start your vehicle without the need to press a button or use a key. However, it can be frustrating when the remote stops working and the check engine light comes on.
In this blog post, we will delve into the common causes behind why remote start may fail, and the check engine light may be activated. By the end of this post, you’ll have a better understanding of these issues.
Causes of Remote Start Not Working and the Check Engine Light:
Below are the common causes of the remote start not working and the check engine light being on:
1: Loose Gas Cap:
A loose Gas cap is one of the common causes that stop working of a remote start. A loose gas can allow the escape of fuel vapor from the fuel tank, which may turn on the check engine light due to an evaporative emissions system error. A loose Gas cap is one of the common issues that is often resolved by simply tightening the Gas Cap.
2: Low on Oil:
Engine oil is used to lubricant different engine components. When your vehicle engine oil is low from the recommended level, it can reduce the lubricant of engine components and, as a result, the check engine light on and remote stop working. It is recommended that you regularly check and maintain engine oil to prevent costly damage.
3: Dirty Engine Oil:
Dirty or contaminated engine oil can have an adverse effect on engine performance. When your vehicle’s engine oil becomes dirty over time, it can reduce lubrication, which can lead to increased wear and potential engine issues.
Remote start functionality can be affected due to dirty engine oil issues, and the check engine light is triggered to inform you about the potential problem.
4: Worn Fuel and Oil Filters:
Fuel and oil filters become clogged and dirty over time, reducing the efficiency of fuel delivery and oil circulation. This can lead to engine problems and poor performance and may cause the check engine light to illuminate.
It is recommended to replace filters at intervals, which is vital for maintaining the health of your vehicle.
5: Ignition System Issues:
Ignition system problems, such as worn-out spark plugs, malfunctioning ignition coils, or damaged ignition wires, can lead to engine misfires. These misfires can significantly affect engine performance, potentially causing the check engine light to illuminate and preventing the remote start from functioning properly.
Therefore, regular inspection and replacement of ignition components are crucial for ensuring a smooth engine operation and the correct functioning of the remote start system.
Engine overheating can occur due to issues such as a malfunctioning cooling system, low coolant levels, or coolant leaks. Overheating can lead to engine damage and the potential activation of the check engine light, as well as a loss of remote start functionality.
It’s crucial to promptly address overheating issues by inspecting the cooling system and addressing any coolant leaks to prevent damage and maintain the proper operation of the remote start system.
7: ECU Errors:
Errors in the Engine Control Unit (ECU) or the vehicle’s computer system can disrupt engine control. This can lead to both remote start problems and the check engine light being illuminated. Addressing ECU errors may involve diagnostic testing and updates or repairs.
8: Low Battery Voltage:
A weak or dead battery in your vehicle or the remote start system can lead to remote start failures. Low battery voltage can also impact the electrical system and potentially trigger the check engine light. Regular inspection and timely replacement of batteries are recommended to ensure proper operation.
9: Exhaust System Issues:
Problems in the exhaust system, such as a damaged catalytic converter or exhaust leaks, can have a negative impact on engine performance. These issues can result in reduced power and emissions problems.
The remote start system may cease working when such issues arise, and the check engine light illuminates to inform you about potential problems with your vehicle.
10: Software or Computer Issues:
Modern vehicles rely heavily on computer systems to control various functions. Software glitches or issues with the vehicle’s computer can lead to both remote start and engine problems. A technician may need to diagnose the issue, update or reset the software, and perform necessary repairs.
11: Wiring Problems:
Damaged or corroded wiring within the vehicle’s electrical system can disrupt the operation of the remote start system and may result in the activation of the check engine light. Remote start functionality can also be affected by this issue. Identifying and repairing these wiring issues is crucial to ensure the proper functioning of the vehicle.
To address these issues, it’s advisable to consult a professional, qualified mechanic or dealership. They have the expertise and diagnostic tools needed to pinpoint the specific problem and perform the necessary maintenance or repairs. Additionally, they can interpret the check engine light codes to identify the exact issue triggering the warning light.
In this blog post, we’ve explored the common causes behind remote start failures and the activation of the check engine light. Common factors contributing to these issues include engine components such as oil, filters, and the ignition system.
When issues do arise, it’s best to turn to the expertise of a professional, qualified mechanic or a reputable dealership. They have the diagnostic tools and knowledge to pinpoint the specific problem and provide the necessary maintenance or repairs. Furthermore, their ability to interpret the check engine light codes allows them to identify the exact issue that triggered the warning light.
By addressing these concerns promptly and effectively, you can ensure the smooth operation of your vehicle and enjoy the convenience of your remote start system without the frustration of unexpected issues.
Q1: Why is my Chevy remote start not working?
A1: There are several factors that could be causing your Chevy remote start issues. It could be a low battery in your key fob, a malfunction in the remote start system, or other electrical problems.
Q2: Can a key fob cause the check engine light to come on?
A2: No, a key fob cannot directly cause the check engine light to come on. The check engine light typically indicates issues with the vehicle’s engine or emissions system. It’s unrelated to the key fob.
Q3: What should I do if my check engine light is on in my Chevy?
A3: If your check engine light is on, it’s essential to have your vehicle’s diagnostic trouble codes (DTCs) read using an OBD-II scanner. This will help identify the specific issue causing the light to come on. You can then take appropriate action to address the problem.
