P2815Pressure Control Solenoid G 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
P2815 is the opposite electrical case: the driver of solenoid G sees battery voltage where the load should pull the pin down. In GM's 2016 eight-speed table, where G is the converter clutch pressure valve, the flag must stand for 0.3 s of a 0.5 s window and one trip is enough. The 2023 Corvette dual-clutch software, with G as the limited-slip valve, also books two further checks here: estimated current deviating from target by over 70 % for 60 ms or by 200 mA for 300 ms, and a short to a neighbouring output found during the shutdown test and set at the next start, rated Type B. Ford lists a shorted load on the TR9070 even clutch cooling valve under this code. Check the harness for contact with a supply wire before replacing parts.
What you may notice
  • MIL lit and transmission in a substitute program
  • Harsh engagement or missing converter lockup
  • Code may appear only after the next engine start (shutdown test)
Likely causes
  • LikelyControl wire of solenoid G touching a supply voltage wire
  • PossibleSolenoid coil with shorted turns drawing too much current
  • RareTwo solenoid outputs shorted together inside the harness or valve body
  • RareFaulty driver stage in the transmission module
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
