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.

Likely causes

Control wire shorted to a supply line
Short to an adjacent solenoid output
Moisture in the connector

Symptoms

  • Gear preselection fails, limp mode
  • Code back immediately after restart
  • MIL on
