The Nissan P1772 error code indicates a problem with the low coast brake solenoid valve in your vehicle's continuously variable transmission (CVT). This solenoid controls hydraulic pressure for smooth shifting and engine braking, and when it fails, you may experience rough shifting, poor acceleration, or the vehicle going into limp mode.

How to Fix Error Code P1772

  1. Safety First - Prepare Your Vehicle

    Never work under a running vehicle or on hot transmission components. Always use proper jack stands if lifting the vehicle.
  2. Connect OBD2 Scanner and Verify Code

  3. Check Transmission Fluid Level and Condition

    CVT fluid is different from regular ATF. Use only Nissan-specified CVT fluid NS-2 or NS-3.
  4. Inspect Transmission Wiring Harness

  5. Test Solenoid Resistance

    Ensure ignition is OFF before disconnecting electrical components to prevent damage to control modules.
  6. Replace CVT Fluid and Filter (If Contaminated)

    Use only genuine Nissan CVT fluid. Incorrect fluid can cause permanent transmission damage.
  7. Replace Solenoid Pack (If Defective)

    This step requires transmission disassembly. If uncomfortable with this procedure, seek professional service.
  8. Clear Codes and Test Drive
