The reason the engine malfunction indicator light flashes is due to an abnormal air-fuel ratio detected by the oxygen sensor in the vehicle. When the engine malfunction light flashes, three scenarios may occur: 1. The warning light is on, but there are no noticeable driving issues. This might indicate a faulty sensor, and you can continue driving temporarily, preferably at low speeds. 2. The engine malfunction light is on, and the vehicle can still be driven, but with severe shaking or lack of acceleration power. In this case, roadside assistance is needed. 3. The car cannot start, which might be caused by a faulty fuel pump or ignition components. In this situation, you should call for emergency assistance.

Why is there no sound when playing music after successful Bluetooth connection in Honda CRV?

The reasons and solutions for no sound when playing music after successful Bluetooth connection in Honda CRV: Volume not turned on: The volume on the car navigation system or mobile phone is not turned on. Solution: Go to "Settings" - "Sound" on the phone, find the "Media" option, and turn up the "Media" volume. The same applies to the car navigation system. Incompatible pairing code: The music playback programming of some mobile phones (such as iPhone) is incompatible with the pairing code of certain car models, so only phone calls can be made but music cannot be played. Solution: It is recommended to change the Bluetooth playback frequency band for normal use. Media audio not turned off: The media audio on the phone is not turned off, causing signal interference with the Bluetooth function. Solution: Turn off the media audio while keeping the phone audio, so that the three functions of Bluetooth calls, car music playback (or radio), and phone navigation voice prompts do not interfere with each other.
