Many thanks from Germany. It also worked on my 2004 CRV. This morning when I got into the car, the engine light suddenly came on. I was already panicking that it was something bigger and more expensive. When I opened the tank cap, there was a strong vacuum.
@@hamzabirinci2335 yes, it did. I forget what the problem was but when I was at the Honda Dealer for something else and told them about this, they told me that by disconnecting the battery, the computer loses the code for "check engine." So they couldn't analyze the problem until the light came back.
Sometimes hitting a pothole can activate it. If you do this and it turn back on then you know there is a problem and should look further into it. If it doesn’t then you are good. These sensors can be too sensitive sometimes.
This is effectively a temporary solution to reset the cars store diagnostic trouble codes (DTCs) when a problem is detected. Disconnecting the battery cable temporarily resets the ECU, which can clear any stored DTCs and, as a result, turn off the check engine light. However, this is only a temporary solution because if the underlying issue causing the DTC isn't resolved, the ECU will detect the problem again and trigger the check engine light once more. To properly diagnose and fix the issue causing the check engine light, you should use an OBD-II scanner to retrieve the stored DTCs from the ECU. Once you've identified the problem, you can address it accordingly. In some cases, you may need to consult a professional mechanic for help.
