Driving a Honda Pilot is a dream come true for most people. The SUV comes with high-end features that guarantee comfort, convenience, and performance. One of the features that make Honda Pilot unique is the Variable Torque Management 4-wheel drive (VTM-4). The VTM-4 system provides the necessary traction and stability to get through tough terrains. However, when the VTM-4 light comes on, it can be stressful for any driver. Moreover, when the check engine light illuminates, it can be even more worrying. In this article, we will explore what causes the VTM-4 light and check engine light to come on in a Honda Pilot in 2023, and how to address the issues.
VTM-4 Light
The VTM-4 light is a warning indicator that appears on the dashboard of a Honda Pilot when there is a problem with the VTM-4 system. The system is designed to distribute torque to all four wheels, providing better traction and stability. When the VTM-4 light comes on, it means that the system has detected a malfunction, and the SUV is running on a front-wheel-drive system only. This can be dangerous, especially when driving on slippery or uneven roads.
The VTM-4 light can come on due to various reasons, including:
Low Fluid Level
The VTM-4 system requires a specific type of fluid to function correctly. If the fluid level is low, it can cause the system to malfunction, triggering the VTM-4 light. Checking the fluid level regularly and topping it up when necessary can help prevent this issue.
Worn Out Differential Fluid
The differential fluid in the VTM-4 system can break down over time, causing it to lose its lubricating properties. This can lead to increased friction, resulting in a malfunction of the system. Changing the differential fluid at the recommended intervals can help prevent this issue.
Check Engine Light
The check engine light is another warning indicator that can appear on the dashboard of a Honda Pilot. The light comes on when the engine control module (ECM) detects a problem with the engine or emission control system. The check engine light can be alarming, but it is essential to address the issue promptly to prevent further damage to the SUV.
The check engine light can come on due to various reasons, including:
Loose or Damaged Gas Cap
A loose or damaged gas cap can cause the check engine light to come on in a Honda Pilot. The gas cap is an essential component of the emission control system, and it helps to prevent fuel vapors from escaping into the atmosphere. Checking the gas cap regularly and replacing it when necessary can help prevent this issue.
Malfunctioning Oxygen Sensor
The oxygen sensor in a Honda Pilot is responsible for monitoring the amount of oxygen in the exhaust system. If the sensor is malfunctioning, it can cause the ECM to adjust the air-fuel mixture incorrectly, resulting in decreased fuel efficiency and increased emissions. Replacing a malfunctioning oxygen sensor can help resolve this issue.
Conclusion
The VTM-4 light and check engine light are essential warning indicators that can help prevent further damage to a Honda Pilot. It is crucial to address any issues promptly to prevent further damage to the SUV. Regular maintenance, including checking fluid levels, replacing worn-out parts, and replacing faulty sensors, can help prevent these issues from occurring. If you notice any warning indicators on your Honda Pilot, it is best to seek the assistance of a certified Honda technician.
