Does the Dongfeng Nissan P0846 fault need to be repaired?

Dongfeng Nissan P0846 fault needs to be repaired. The P0846 fault is a transmission pressure sensor fault, and the transmission valve body needs to be replaced. The symptoms of a damaged transmission valve body are: 1. After the transmission develops a fault, the computer can detect it, and the fault light will illuminate to alert, entering the lock-up state, which is the protection mode; 2. The transmission oil temperature is too high, causing the transmission to jerk. Taking the 2021 Venucia D60 1.6L Entry Manual Comfort Edition as an example: its length, width, and height are 4756mm, 1803mm, and 1487mm respectively, with a wheelbase of 2701mm, equipped with a 5-speed manual transmission, the body type is a 4-door 5-seater sedan, and the maximum speed reaches 180 kilometers per hour.
My Dongfeng Nissan had previously thrown the P0846 trouble code, and at the time, I felt like the transmission was constantly stuck in a certain gear, making starts and acceleration less smooth. Initially, I thought it was a minor issue and ignored it, but after a few weeks, the fuel consumption skyrocketed, and there was a "clicking" sound when parked. That's when I panicked and rushed to the repair shop for a check. The technician tested the wiring and sensors and found it was a valve body issue. Replacing a small part fixed it, costing just over a thousand yuan in total. Looking back now, I really regret delaying it—if the transmission had been damaged, repairs would have cost several thousand. So, this kind of fault can't wait; it affects driving safety, especially on highways where gear shifting issues can easily lead to accidents. My advice is not to gamble with luck—get it checked at a professional shop sooner rather than later. Early action means peace of mind, saving both hassle and money.
