What does this fault code mean?

The input shaft speed sensor for odd gears gives a value that does not match the other speed values in the transmission. The sensor is also used to check the other two speed sensors, so the fault can affect how the gears are monitored.

Possible causes

Damaged sensor

What you can do

1Read out the fault codes from the transmission control module. If several speed sensors show faults, the cause may instead lie in the control module
2If you have diagnostic equipment, compare the input shaft speed for odd gears with the other speed values in live data while the car is rolling and see whether it deviates
3Check the connector at the sensor for the odd gears: see whether it is secure, clean and free from damage
4If the fault is inside the control module, it must be replaced; a new module is delivered without software and must be programmed by a workshop

Symptoms you may notice5

Yellow warning symbol and message in the display
No forward or reverse movement with a gear selected
Gears shift hard or jerky, sometimes or all the time
Gear changes take too long to complete, sometimes or all the time
