P2824Pressure Control Solenoid J Control Circuit/Open

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
  • Can trigger limp mode
How the car detects it
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.
What you may notice
  • Hydraulic limp gear or no shifting
  • Park lock cannot be operated (dual-clutch models)
  • MIL on after one or two trips
Likely causes
  • LikelyBroken wire between TCM and valve J
  • PossibleTerminal pushed back or not latched in the connector
  • PossibleOpen coil in solenoid J
  • RareFaulty output driver in the TCM
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
