- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- With P27CC the transmission controller has seen solenoid R lose its circuit or its effect for short moments only. A public, code-specific manufacturer description does not exist. The two known users of solenoid R, GM's Corvette dual-clutch transmission (23OBDG07, valve 4) and Ford's TR9070 (SPV4), document only lasting electrical faults and stuck conditions for it. CARB 13 CCR 1968.2 requires output monitoring for automatic transmission solenoids. Since the fault may have healed by the time the car reaches the workshop, freeze frame records, the number of occurrences and a careful look for oil wicking into connectors or a loose pin are more telling than one resistance reading.
