P2735Pressure Control Solenoid F Intermittent
- Generic OBD-II code · Powertrain
- Needs a drive cycle to confirm a fix
- How the car detects it
- By its standard title P2735 reports that solenoid F or its circuit fails only now and then, so a static check in the workshop often finds nothing. GM uses the code differently on the dual-clutch gearbox of the 2023 and 2024 Corvette: there valve F is the clutch cooling valve, and P2735 stands for a stuck lube valve. The TCM triggers a current-profile test on the valve during stable driving with fluid at 60 °C or warmer and a cooling flow target below 3 l/min; if the result keeps indicating failure, it sets the code. GM rates it Type C, so it does not switch on the MIL. Other makers do not document P2735 publicly. Intermittent wiring or connector faults on valve F are the generic reading, while the Corvette case points to the cooling valve itself.
