DQ250 Valve / solenoid electrical Review
Description

What P1825 indicates

The DQ250 transmission control unit stores P1825 when it detects the following condition: Pressure control valve 3 / N217 — short to plus. The fault is electrical: the control unit monitors the current and resistance of each solenoid and pressure control valve, and stores the code when it detects an open circuit, a short circuit or a control current outside the expected range. A stored code does not by itself prove that a part has failed. Before replacing anything, check the live data, wiring, connectors, power supply and fluid condition, and confirm the fault on the vehicle.

  • Some gears unavailable

Possible causes

  • Faulty solenoid or pressure control valve coil
  • Damaged internal wiring or connector in the mechatronic unit
  • Fault in the valve driver stage of the control electronics
  • Contaminated transmission fluid affecting valve operation
