Brilliance Auto p0507 Fault

Idle speed is too high, which is higher than the acceptable range expected by ECU, and the throttle valve is damaged. Check whether the PCV valve loses vacuum.

The engine crankcase is forced to ventilate and connected with the intake manifold through PCV. Check whether the eardrum of this valve is slightly damaged, and the idle speed should be blocked. After slight air leakage, the air forced to ventilate the engine crankcase is sucked into the combustion chamber by the intake manifold and bypasses the throttle valve.
