Most Reported On
P2767 is an OBD-II diagnostic trouble code meaning “Input/Turbine Speed Sensor "B" Circuit No Signal.” This code is set when the transmission control module receives no signal from the input/turbine speed sensor "B". This sensor measures how fast the transmission input shaft is turning, which the computer uses to time gear shifts correctly. With no signal, the transmission cannot accurately control shifting and often defaults to limp mode, causing harsh, delayed, or failed shifts. It usually indicates a sensor or wiring fault and should be addressed to restore normal transmission operation. This code is most commonly reported on 2005-2011 Mercedes-Benz SLK-Class, with repair costs ranging from $900 to $2,000.
