Brake Pressure Sensor – Skoda Octavia – 1997-2000 – 1J0907597B

Restore correct ABS, ESP and electronic stability control function on your Skoda (1997–2000) with this direct-replacement brake pressure sensor — also known as the brake fluid pressure sensor, ABS pressure sensor or ESP pressure sensor. Built to OEM specification and matching part numbers 55CP15-01, 55CP14-02, 1J0907597B, 1005229960 and 1J0907597. Also fits equivalent Audi, Seat and Volkswagen models.

Common signs of failure

A failing brake pressure sensor typically triggers ABS, ESP and traction control warning lights together, with fault codes around the brake pressure circuit (manufacturer-specific). Drivers report the hill-hold function failing, electronic parking brake errors on some models, and the stability/traction systems disabled. Braking itself still works mechanically, but the active safety systems that depend on knowing pressure-on-the-pedal are offline.

Fitment notes

Direct-fit replacement, threaded into the ABS hydraulic module or master cylinder. The brake system will need bleeding after fitting to remove any air introduced during the swap — use the correct DOT-rated fluid. Clear codes with a scanner after installation. Standard 3 pin connector.

Frequently asked questions

Will I lose my brakes if this sensor fails?

No — mechanical braking is unaffected. The fault disables electronic assistance (ABS, ESP, hill-hold) but you can still stop the car using the brake pedal normally.

Do I need to bleed the brakes after fitting?

Yes — any time a brake hydraulic component is removed, bleed the system to remove trapped air. Most modern ABS systems also benefit from a scanner-driven bleed sequence.

Will the warning lights clear automatically?

After fitting and bleeding, clear codes with an OBD2 scanner. On most vehicles a short drive above 12 mph will then reset the ABS/ESP modules.
