What P2824 means
P2824 reports an open in the control line of solenoid J. GM's 2016 table for T87 eight-speed controllers uses J for the on/off boost valve of clutch 2 and flags the code in one trip once the fault persists 0.3 s within a half-second sample. In the 2020 tables the code is limited to T93 ten-speed controllers, where J is the default disable valve, and an impedance near 200 kilohm between signal and ground leads to Type A. The 2023 Corvette dual-clutch box tests its park lock engaging valve while switched off: if the pin can be held between about 1.7 and 3 V with a tiny current, no load is connected, and after 150 ms a Type B code is set. Ford's TR9070 files an open park lock valve here. Broken wires, backed-out terminals or an open coil are typical.
P2824 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 P2824
- Hydraulic limp gear or no shifting
- Park lock cannot be operated (dual-clutch models)
- MIL on after one or two trips
Common causes of P2824
- Most likelyBroken wire between TCM and valve J
- PossibleTerminal pushed back or not latched in the connector
- PossibleOpen coil in solenoid J
- Less likelyFaulty output driver in the TCM
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2824 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. |
| 24 | The exact fault in that area. |
What to do next
- Note P2824 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 P2824
What does P2824 mean?
P2824 means "Pressure Control Solenoid J Control Circuit/Open". P2824 reports an open in the control line of solenoid J. It is a generic code, so it means the same on every make.
Is it safe to drive with P2824?
Drive gently and only to a workshop. With P2824 the car can go into limp mode (reduced power) to protect itself.
Will P2824 fail an emissions test?
Yes, it can. P2824 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 P2824 to fix?
Difficulty: hard. A typical repair takes 1 to 6 hours of work. This is a job for a workshop.
Will P2824 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
