If the check engine light on your 2011 Honda Odyssey turns on, it means there is an issue with the vehicle that has been logged in the ECU. To find out what's wrong, you'll need to use an OBD II scan tool to retrieve the codes. One common reason for the light to come on is a problem with the EVAP system, often caused by a faulty gas cap. It's best to address the root cause of the issue rather than just clearing the light. By keeping a record of the codes stored in the ECU, you can assist your mechanic in diagnosing future problems.
The top causes of a check engine light illuminating in a 2011 Honda Odyssey are typically a loose gas cap, low coolant levels, a misfire in the engine, or leaks in the emissions system.
