To clear the check engine code on a Volvo 850, you can use an OBD-I scanner to retrieve and erase codes. Alternatively, you can disconnect the car's battery for about 10-15 minutes, which will reset the engine control unit (ECU) and clear the codes. After reconnecting the battery, drive the vehicle for a short distance to ensure the system resets properly. However, it's important to address the underlying issue that triggered the code before clearing it.
