P2824 Pressure Control Solenoid J Control Circuit/Open

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.

Likely causes

Broken wire between TCM and valve J
Terminal pushed back or not latched in the connector
Open coil in solenoid J
Faulty output driver in the TCM

Symptoms

  • Hydraulic limp gear or no shifting
  • Park lock cannot be operated (dual-clutch models)
  • MIL on after one or two trips
