P0507 idle control speed exceeds the specified value conditions: When the vehicle starts in warm condition, it first starts with high idle speed at around 1000 rpm, then the speed drops to 720 rpm, and finally the idle speed rises to 800 rpm and stabilizes at this idle speed. Inspect the intake system and confirm that the carbon canister solenoid valve N80 and exhaust gas pressure regulating valve are damaged. After replacement, the engine flow meter value returns to normal. The increase in idle speed means that to optimize the power supply of the electrical system and the charging condition of the battery, the battery management system can request the engine control unit to increase the engine speed to meet the current state demand.
