P2827Pressure Control Solenoid J 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
- P2827 sets when the J control line shows supply voltage although the load ought to pull it low. In GM's 2020 tables it covers the nine-speed clutch valve, the ten-speed default disable valve and the eight-speed boost valve, using the same 0.3-of-0.5 s window and Type A rating as the low code. On the Corvette's 2023 dual-clutch unit, where J engages the park lock, the limit grows with battery voltage from about 0.7 to 1.1 V; this code also takes a current estimate that misses its target by more than 70 % (60 ms) or 200 mA (300 ms). A further check at shutdown looks for a short to the next output and raises it at the following key cycle; all of these are Type B. Ford files a shorted load at the TR9070 park lock valve here. Check for wires touching a supply line.
