P2736Pressure Control Solenoid F Control Circuit/Open
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2736 points to an open control circuit on solenoid F, meaning the coil path is interrupted. GM documents the code for several gearboxes. On the eight-speed of 2016 valve F is the line pressure solenoid, and an open-circuit flag for 0.3 s within 0.5 s sets the fault in one trip. In 25OBDG03A the same valve drives clutches on the nine- and ten-speed or switches the CVT's binary pump, and an impedance above 200 kOhm to ground over the same window is a Type A fault. The Corvette dual-clutch TCM tests its clutch cooling valve while switched off and flags open load at a sense voltage of roughly 1.7 to 3.0 V for 150 ms. Ford's TR9070 uses P2736 for open load on the odd clutch cooling valve. Line pressure faults usually bring a limp mode.
- What you may notice
- MIL on and limp-home mode
- Firm shifts from maximum line pressure or missing gears
- Likely causes
- LikelyBroken wire or pushed-back terminal
- PossibleValve body connector not fully seated
- PossibleOpen winding in solenoid F
- RareInternal TCM fault
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
