P2830Pressure Control Solenoid K Control Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- 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.
