2 vehicles · 2 makes · $300-$4,500 repair
Most Reported On
P2765 is an OBD-II diagnostic trouble code meaning “Input/Turbine Speed Sensor "B" Circuit No Signal.” A generic powertrain code indicating the transmission control module (TCM/PCM) is receiving no signal from the "B" (secondary) input/turbine speed sensor circuit. This sensor reports rotational speed of the input/turbine shaft, which the controller uses to manage shift timing and torque converter lockup; without its signal the module cannot accurately determine input shaft speed. This code is most commonly reported on 2017-2025 Volkswagen Golf R (MK7.5 R (DSG), MK8 R (DSG)), and 2019-2024 Audi SQ2 (7-speed S tronic), with repair costs ranging from $300 to $4,500.
