P2767 on Mercedes-Benz
Input/Turbine Speed Sensor "B" Circuit No Signal
P2767 on Mercedes-Benz vehicles indicates input/turbine speed sensor "b" circuit no signal. Au7o has documented this code across 1 Mercedes-Benz model — most commonly on SLK-Class. 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. Typical repair costs on Mercedes-Benz range from $900 to $2,000, depending on the specific model and root cause.
Common Causes of P2767
- •Faulty input/turbine speed sensor B
- •Open or shorted sensor wiring
- •Corroded or loose connector
- •Damaged reluctor/tone ring
- •Low or contaminated transmission fluid
- •Internal valve body or transmission fault
- •Faulty TCM
P2767 on Mercedes-Benz by Model
Mercedes-Benz SLK-Class(1 issue)
- 7G-Tronic Conductor Plate / Speed Sensor Failure2005-2011
The 722.9 7G-Tronic automatic transmission used in later R171 models is known for conductor plate and internal speed sensor failures. When the plate or sensors fail, the transmission may enter limp mode, shift harshly, or get stuck in one gear due to loss of accurate input/output speed data.
