P2736 Pressure Control Solenoid F Control Circuit/Open

Drive cycleNot required
Limp modePossible

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.

Likely causes

Broken wire or pushed-back terminal
Valve body connector not fully seated
Open winding in solenoid F
Internal TCM fault

Symptoms

  • MIL on and limp-home mode
  • Firm shifts from maximum line pressure or missing gears
