P1577 Fault Code: Understanding The Description And Troubleshooting Steps
The P1577 code is triggered when the PCM detects that the Brake Booster Vacuum (BBV) has a low input signal.
This means that the BBV is not generating enough vacuum pressure for the brake system to function properly.
When the BBV vacuum pressure drops to -8 kPa or less for a duration of 2 seconds, the P1577 code is set. This indicates a problem with the brake booster vacuum sensor circuit. If you encounter this fault code, it is important to have the brake system inspected and repaired as soon as possible.
A malfunctioning brake booster vacuum can affect the performance of your brakes, compromising your safety on the road.
