Transmission Speed Sensor, Input Speed

WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2014 Volvo XC90, 2013 Volvo XC90, 2012 Volvo XC90, 2011 Volvo XC90, and 2010 Volvo XC90. However, it is still accessible from the selected car via links, so may be relevant.

The speed can be generated with the engine idling and the gear selector in P/N position. If the gear selector is in any other position, a gear is engaged and the transmission input shaft is connected to the output shaft and an RPM will not be indicated until the car is driven. Depending on slippage in the torque converter the transmission speed and the engine speed will differ when the lock-up function is not engaged. With lock-up engaged the transmission speed should be the same as engine speed (RPM).

Measurement range (rpm): 0 -

Peak = 14 mA

Trough = 7 mA
