INFINITI Q70 brake vacuum sensor issue pending diagnosis on INFINITI Q70

Some INFINITI Q70 owners report experiencing issues related to the brake vacuum sensor, such as a stiff brake pedal and illuminated Check Engine Light, indicating potential vacuum problems. These symptoms may arise from a faulty brake vacuum sensor or a malfunctioning brake booster vacuum pump, posing a safety risk that requires prompt attention. Additionally, some owners notice the brake light and traction light activating, particularly during rapid acceleration, which may also be linked to the brake vacuum sensor issue. Accumulation of dirt around the sensor can lead to inaccurate readings and trigger warning lights on the dashboard, suggesting a problem with the ABS system. Given the critical role of the ABS control module in managing braking functionality, it is essential for owners to have any brake vacuum sensor concerns diagnosed and resolved by a qualified technician to ensure vehicle safety and performance.
