What Does The P17F1 Code Mean In Nissan Vehicles?
The P17F1 code is a manufacturer-specific diagnostic trouble code (DTC). When this code is logged in Nissan models, it is defined as “CVT Judder”. The code indicates a problem with the continuously variable transmission (CVT) belt slip, leading to juddering or vibration during acceleration or while driving. Proper diagnosis and repair are necessary to address this issue and restore optimal CVT performance.
Let’s have some background information about CVT first. CVT, or Continuously Variable Transmission, is a type of automatic transmission commonly found in Nissan vehicles. Unlike traditional transmissions, CVTs don’t have fixed gears but instead use pulleys and a belt or chain to provide a continuous range of gear ratios. This results in smooth acceleration and improved fuel efficiency.
