P27C3Pressure Control Solenoid P 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
- P27C3 is the general electrical fault code for pressure control solenoid P. No manufacturer documents it publicly. Where solenoid P is known to exist, on GM's Corvette dual-clutch box (23OBDG07, shift solenoid 3) and Ford's TR9070 (SPV3), electrical faults are reported in finer detail: P27C5 for an open load, P27C7 for a shorted switch and P27C8 for a shorted load or excessive current error. A controller with simpler output diagnostics might summarize any of these as P27C3. CARB 13 CCR 1968.2 requires monitoring of transmission output circuits. Measure coil resistance at the transmission connector, then check terminals and the lead to the control unit.
