TSB: Mazda ABS Sensor Update

This bulletin applies to 2024-2026 Mazda CX-90 vehicles and 2025-2026 CX-70 vehicles,  built before November 8, 2025. Some vehicles may exhibit a key-in lock situation when the speed-sensitive door lock activates unexpectedly when idling in Park. This may be caused by the noise generated by the ABS wheel speed sensor being mistakenly recognized as a vehicle speed pulse. To eliminate this concern, the IC chip in the ABS wheel speed sensor has been modified. Replace the ABS wheel speed sensors on both sides of the rear wheels, using P/N KEME-43-7EXA (right) and KEME-43-7EYA (left).
