P2825 Pressure Control Solenoid J Control Circuit Range/Performance

EmissionsRelevant
Drive cycleNot required

P2825 would flag a J control circuit that is intact but behaves implausibly, for example a current that does not track the duty cycle the module commands. No manufacturer documents this code publicly, and CARB 13 CCR 1968.2 only requires functional checks of output circuits in general terms. The Corvette dual-clutch software of 2023 does run such a comparison on its J valve, the park lock engaging valve, estimating current from duty cycle and battery voltage, but it books a deviation above 70 % for 60 ms or 200 mA for 300 ms under the high-side code P2827. If P2825 is stored, compare coil resistance with specification at operating temperature, measure contact resistance at the terminals and check the driver supply; a sluggish valve can mimic this fault.

Likely causes

Coil resistance out of specification when hot
High contact resistance at terminals
Sluggish valve J changing the electrical load

Symptoms

  • Shift quality varies
  • MIL or transmission warning

Repair estimate

Parts and labour€80–2,500
