DTC Description

WARNING: This page is about a different variant/trim than selected.

DTC P073100 is set when the number of revolutions of the output shaft and the input shaft that are multiplied by the gear ratio at the first speed are not matched. This DTC is more likely to be caused by mechanical defects due to the control valve being stuck or solenoid valve malfunction than electrical defects.
