P0700 on a Nissan: Causes, Fixes & Repair Cost

🟠 Moderate severity · drivable

You can usually drive a Nissan short-term with P0700, but stop if the CVT slips, shudders, or feels jerky.

What P0700 means on a Nissan

On a Nissan, P0700 is the transmission control module flagging a stored fault to the engine computer. The specific problem is saved as a separate code in the TCM that a basic OBD2 reader cannot see. On Nissans with the Xtronic CVT, the code often points to the CVT control system rather than the engine.

Is P0700 common on Nissans?

P0700 shows up on Nissans with automatic and CVT transmissions, especially Altimas, Rogues, and Sentras. Nissan CVTs are sensitive to fluid condition, and low or old CVT fluid can trigger TCM faults. Speed sensors and the CVT control unit are common failure points.

Commonly reported on: Altima, Rogue, Sentra, Pathfinder.
