• P0676: Cylinder 6 glow plug circuit/open circuit. This usually indicates that the glow plug or its circuit is open or disconnected, which may affect the normal ignition of the cylinder.
• P0B99: Hybrid battery voltage monitoring S circuit intermittent/unstable. This refers to an abnormality in the voltage monitoring function of the hybrid battery system, which may cause battery performance degradation or system failure.

2. Fault codes starting with P1:

• P1895: Continuously Variable Transmission (CVT) – Acceleration is too weak. This may mean that the CVT transmission has insufficient performance when accelerating, which may be caused by a variety of reasons, such as internal transmission failure, sensor problems, or control system abnormalities.
• P1576: Brake booster vacuum (BBV) sensor – high voltage. This means that the voltage output of the brake booster vacuum sensor is abnormally high, which may affect the normal operation of the brake booster system.
