Common causes

  • Low or contaminated transmission fluid
  • Faulty pressure control solenoid
  • Valve body problems
  • Damaged wiring

Symptoms

  • Harsh, slipping or delayed shifts
  • Stuck in one gear (limp mode)
  • Shudder

Can I drive with it?

Drive gently and get it checked soon – driving in limp mode or with slipping shifts can damage the transmission.

Tip: Many Nissan CVTs set this code – check for a software update or extended warranty on your model before paying for a repair.

Which scanner reads it?

Any OBD2 scanner reads the basic code. A multi-system scanner can read the transmission module directly; some can command the solenoids.

Budget tools like the ANCEL AD310 read it; tools with live data and graphing – like the BlueDriver or OBDLink MX+ – help you find the cause. Not sure which fits you? Try the Find My Scanner quiz.
