P2822Pressure Control Solenoid J Electrical

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
  • Can trigger limp mode
How the car detects it
P2822 gathers electrical faults of solenoid J without saying whether the circuit is open or shorted; a failure-type byte adds that detail. Mercedes-Benz uses the code on two gearboxes, and in both J is pressure regulating valve 9. For the 9G-Tronic (transmission 725.0), information LI27.60-P-064292 reports P282212, a short to positive at valve 9, together with P060C00 on new C-, E- and S-Class cars (series 205, 213, 222) as they leave transport mode; there the fix is to let the car sleep and then clear the memory, while the note stresses that real faults remain possible. On the 8G-DCT, P282200 is part of the IPR guided test. GM splits J wiring faults into P2824, P2826 and P2827. Start with coil resistance and the gearbox connector.
