Fault code 4460 Pressure sensor

Pressure sensor actual value is evaluated and displays an implausible value.

Possible cause of fault

- Short circuit to ground/8+ or open circuit

- Plug connection on stop light switch faulty

- Incorrect adjustment of the stop light switch

- Wiring/plug connection between pressure sensor and control module faulty

- Pressure sensor faulty

NOTE: A malfunction of the stop light switch can cause this fault. The stop light switch must have switched before a brake pressure is recognized. When the brake pedal is actuated, the stop light switch and the brake lights are triggered. The brake pressure on the pressure sensor is 0 bar.

So, check your brake lights first.
