What P2825 means
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.
P2825 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyHard
- Typical labor1 to 6 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2825
- Shift quality varies
- MIL or transmission warning
Common causes of P2825
- PossibleCoil resistance out of specification when hot
- PossibleHigh contact resistance at terminals
- Less likelySluggish valve J changing the electrical load
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2825 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 8 | Area: transmission. |
| 25 | The exact fault in that area. |
What to do next
- Note P2825 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2825
What does P2825 mean?
P2825 means "Pressure Control Solenoid J Control Circuit Range/Performance". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P2825?
Drive gently and only to a workshop. With P2825 the car can go into limp mode (reduced power) to protect itself.
Will P2825 fail an emissions test?
Yes, it can. P2825 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2825 to fix?
Difficulty: hard. A typical repair takes 1 to 6 hours of work. This is a job for a workshop.
Will P2825 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
