Understanding Check Engine Light And Remote Start Issues
When your remote start won’t work, and the check engine light is on, it may indicate a fault in the engine or fuel pump. Low oil pressure or engine coolant levels could also disable the remote start. Ensure proper maintenance and address any engine issues for smooth operation of the remote start.
Why Won’t My Remote Start Work With The Check Engine Light On?
When your remote start fails to work and you notice that your check engine light is illuminated, it can be quite frustrating. It’s important to understand that there may be a connection between these two issues. In this section, we will explore the possible reasons behind the check engine light and remote start problems.
Possible Reasons For Check Engine Light And Remote Start Problems
There are several potential causes that could explain why your remote start won’t work when the check engine light is on. It’s crucial to identify and address these issues to ensure both your remote start functionality and any underlying engine problems are resolved. Here are a few possible reasons:
- Mechanical or electrical issues: A faulty engine component, such as a sensor or ignition coil, can trigger the check engine light and cause remote start failure. It may be necessary to inspect and repair these components to restore functionality.
- Engine performance problems: If your vehicle is experiencing performance issues, such as misfires or low fuel pressure, the check engine light may be signaling these problems. In turn, the remote start function may be disabled as a safety precaution.
- Codes stored in the engine control module (ECM): When the check engine light is on, it means that diagnostic trouble codes (DTCs) have been stored in the ECM. These codes provide information about specific engine issues. Remote start systems often require a clear ECM with no active codes to function properly.
- Low battery voltage: If your vehicle’s battery voltage is too low, the remote start system may be disabled. It’s essential to ensure your battery is in good condition and charged adequately.
- Security system interference: Some vehicles have security systems that can disable remote start functionality if they detect a potential theft attempt. If your vehicle has a security system, it’s worth checking if it’s causing any interference.
It’s worth noting that these are just a few possible reasons for check engine light and remote start problems. It’s recommended to consult a professional mechanic or a dealership to diagnose and fix the specific issue with your vehicle.
