Common Reasons For Vtm-4 Light And Check Engine Light
When the VTM-4 light and the check engine light turn on in your 2015 Honda Pilot, it is crucial to address the issue promptly to avoid further damage to your vehicle. These lights can indicate various problems, from engine misfires to issues with the exhaust system. Understanding the common reasons behind these lights can help you diagnose and resolve the problem efficiently.
Vehicle Stability Assist (vsa) System Issue
One potential cause for the VTM-4 light and check engine light to come on is an issue with the Vehicle Stability Assist (VSA) system. The VSA system is designed to enhance stability and traction by applying brake force to individual wheels when necessary. However, if there is a problem with this system, such as a faulty sensor or a malfunctioning component, the VTM-4 light and check engine light may be triggered. It is important to have the VSA system thoroughly inspected and repaired by a qualified technician.
Engine Misfire
Another common reason for the VTM-4 light and check engine light to illuminate is an engine misfire. An engine misfire occurs when one or more cylinders in the engine fail to ignite the fuel-air mixture properly. This can be caused by various factors, including a malfunctioning spark plug, a clogged fuel injector, or a problem with the ignition system. When an engine misfire is detected, the VTM-4 light and check engine light may turn on to alert you of the issue. It is crucial to have the engine examined and repaired to prevent further damage and potential loss of power.
Exhaust System Problems
The exhaust system is responsible for removing harmful gases from the engine and reducing noise. However, if there is a problem with the exhaust system, such as a leak, a faulty catalytic converter, or improper fuel-air mixture, it can trigger the VTM-4 light and check engine light. These lights serve as a warning that there may be an issue with the emissions system. It is essential to have the exhaust system inspected and repaired to maintain optimum performance and fuel efficiency.

However, before you start panicking, there are some troubleshooting tips you can try to identify and resolve the issue. In this section, we will discuss the steps you can take to check the VTM-4 system, inspect the oxygen sensor, and examine the ignition system.
Check The Vtm-4 System
In order to troubleshoot the VTM-4 light on your Honda Pilot, you should first check the VTM-4 system. This system is responsible for enhancing the vehicle’s traction and stability by automatically transferring power between the front and rear wheels. Follow these steps to check the VTM-4 system:
- Start the engine and let it run for a few minutes
- Move the shift lever to “D” or drive
- Drive the vehicle for a short distance to warm up the transmission fluid
- Stop the vehicle in a safe location and engage the parking brake
- Turn off the engine and wait for a few minutes
- Restart the engine and see if the VTM-4 light is still illuminated. If it is, there may be an issue with the VTM-4 system that requires further inspection.
Inspect The Oxygen Sensor
The oxygen sensor plays a crucial role in monitoring the amount of oxygen in the exhaust gases. A faulty oxygen sensor can cause the check engine light to come on. To inspect the oxygen sensor on your Honda Pilot:
- Locate the oxygen sensor, which is typically located near the exhaust manifold
- Check for any visible signs of damage, such as loose connections or corroded wires
- If you notice any issues, replace the oxygen sensor with a new one
- Reset the check engine light by disconnecting the negative battery cable for a few minutes
- Reconnect the battery cable and start the engine to see if the check engine light has turned off
Examine The Ignition System
The ignition system is responsible for providing the spark that ignites the fuel-air mixture in the engine. A misfiring ignition system can trigger the check engine light and affect the performance of your vehicle. To examine the ignition system:
- Check the spark plugs for any signs of wear or damage
- Inspect the ignition coils for cracks or other issues
- If necessary, replace the spark plugs and ignition coils
- Clear the check engine light by using an OBD-II scanner or disconnecting the battery
- Start the engine to see if the check engine light remains off
By following these troubleshooting tips, you can hopefully identify and resolve the issues related to the VTM-4 and check engine light on your 2015 Honda Pilot. However, if the problem persists, it is recommended to consult a qualified mechanic or take your vehicle to a Honda dealership for further diagnosis and repair.
