Code P0732 Lexus Description
The P0732 code for a Lexus indicates that there is an incorrect gear ratio detected in the transmission's second gear. This can lead to various issues with the vehicle's performance, including poor acceleration, reduced fuel efficiency, and potential transmission slipping or harsh shifting. The transmission control module (TCM) monitors the gear ratios to ensure smooth operation and optimal performance. When it detects that the actual gear ratio in second gear does not match the expected ratio, it triggers the P0732 code.
