What P2830 means
P2830 is set when the K control line carries voltage where the switched-on low-side driver should pull it down. GM applies it to the selector pilot valve of the 2023 Corvette dual-clutch box with a limit that climbs as supply voltage increases, from about 0.7 V below 11.5 V to 1.1 V above 15.5 V, confirmed after 100 ms. The same code also records a current estimate that misses the target by more than 70 % for 60 ms or by 400 mA over 300 ms; a short to an adjacent output, which a shutdown test writes to memory, is reported at the next start as well. Every variant is rated Type A, unlike the Type B rating of the park lock valve J. Ford's TR9070 lists a shorted load at its selector pilot valve as P27E0. Look for wires rubbing on supply lines and for moisture in connectors.

Symptoms of P2830
- Gear preselection fails, limp mode
- Code back immediately after restart
- MIL on
Common causes of P2830
- Most likelyControl wire shorted to a supply line
- PossibleShort to an adjacent solenoid output
- PossibleMoisture in the connector
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2830 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. |
| 30 | The exact fault in that area. |
What to do next
- Note P2830 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 P2830
What does P2830 mean?
P2830 means "Pressure Control Solenoid K Control Circuit High". P2830 is set when the K control line carries voltage where the switched-on low-side driver should pull it down. It is a generic code, so it means the same on every make.
Is it safe to drive with P2830?
Drive gently and only to a workshop. With P2830 the car can go into limp mode (reduced power) to protect itself.
Will P2830 fail an emissions test?
Yes, it can. P2830 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 P2830 to fix?
Difficulty: hard. A typical repair takes 1 to 6 hours of work. This is a job for a workshop.
Will P2830 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
