C1288: Pressure Transducer Circuit Malfunction
3 vehicles · 2 makes · $200-$2,500 repair
Most Reported On
C1288 is an OBD-II diagnostic trouble code meaning “Pressure Transducer Circuit Malfunction.” This chassis/brake code indicates a malfunction in the brake pressure transducer (sensor) circuit, which is part of the ABS and stability control system. The pressure transducer measures hydraulic pressure in the brake system so the control module can manage anti-lock braking, traction, and stability functions accurately. The module sets this code when the transducer's signal is missing, out of range, or implausible. Note this code is manufacturer-specific: on many Ford/Mazda/Volvo applications it points to a brake pressure sensor failure (often integrated into the ABS unit), while some other brands use C1288 for a different sensor mismatch — so the exact meaning should be confirmed against the vehicle's service information. It generally results in ABS and stability/traction control being disabled while normal braking remains. This code is most commonly reported on 2009-2019 Ford Flex, 2021-2025 Ford Bronco Sport, and 2007-2015 Mazda CX-9, with repair costs ranging from $200 to $2,500.

It generally results in ABS and stability/traction control being disabled while normal braking remains.
What are the most common causes of C1288?
The most common causes of C1288 are: Faulty brake pressure transducer / pressure sensor, Internal fault in the ABS hydraulic control unit (where sensor is integrated), Damaged wiring or connector in the transducer circuit, Corrosion or poor contact at the sensor connector, Open or short in the sensor circuit, Faulty ABS / stability control module, Module configuration mismatch after a part replacement (on certain brands). The specific cause varies by vehicle.
How much does it cost to fix C1288?
Repair costs for C1288 range from $200 to $2,500, depending on the vehicle and root cause.
