What P2827 means
P2827 sets when the J control line shows supply voltage although the load ought to pull it low. In GM's 2020 tables it covers the nine-speed clutch valve, the ten-speed default disable valve and the eight-speed boost valve, using the same 0.3-of-0.5 s window and Type A rating as the low code. On the Corvette's 2023 dual-clutch unit, where J engages the park lock, the limit grows with battery voltage from about 0.7 to 1.1 V; this code also takes a current estimate that misses its target by more than 70 % (60 ms) or 200 mA (300 ms). A further check at shutdown looks for a short to the next output and raises it at the following key cycle; all of these are Type B. Ford files a shorted load at the TR9070 park lock valve here. Check for wires touching a supply line.
P2827 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 P2827
- Limp gear or blocked park lock function
- Code returns right after a restart
- MIL on
Common causes of P2827
- Most likelyControl wire shorted to a supply line
- PossibleShort to a neighbouring solenoid output
- PossibleMoisture in the transmission connector
- Less likelyShorted coil turns lowering the load
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2827 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. |
| 27 | The exact fault in that area. |
What to do next
- Note P2827 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 P2827
What does P2827 mean?
P2827 means "Pressure Control Solenoid J Control Circuit High". P2827 sets when the J control line shows supply voltage although the load ought to pull it low. It is a generic code, so it means the same on every make.
Is it safe to drive with P2827?
Drive gently and only to a workshop. With P2827 the car can go into limp mode (reduced power) to protect itself.
Will P2827 fail an emissions test?
Yes, it can. P2827 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 P2827 to fix?
Difficulty: hard. A typical repair takes 1 to 6 hours of work. This is a job for a workshop.
Will P2827 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
