P0745 on Ford
Pressure Control Solenoid Malfunction
P0745 on Ford vehicles indicates pressure control solenoid malfunction. Au7o has documented this code across 1 Ford model — most commonly on Explorer. This transmission code indicates a problem with the pressure control solenoid (also called the line pressure or EPC solenoid), an electronically controlled valve that regulates the hydraulic fluid pressure inside the automatic transmission. The transmission computer uses this solenoid to set the right pressure for smooth, firm shifts, so when it detects an electrical fault or out-of-range performance, it sets this code. The result is often harsh, soft, or erratic shifting, and the transmission may drop into a protective limp mode. It generally points to an electrical or hydraulic issue with the solenoid itself or its control circuit. Typical repair costs on Ford range from $900 to $3,500, depending on the specific model and root cause.
Common Causes of P0745
- •Failed or stuck pressure control (EPC) solenoid
- •Low or contaminated transmission fluid
- •Dirty fluid clogging or sticking the solenoid valve
- •Wiring or connector fault in the solenoid circuit
- •Internal valve body wear or leakage
- •Faulty transmission control module
- •Internal transmission electrical (case connector) short

Ford Explorer(1 issue)
- 5R55W/5R55S Transmission Servo Bore Wear Causing Flare, Slip, and Delayed Reverse2002-2010
A very common failure on third- and fourth-generation Explorers with the 5R55W/5R55S automatic is wear in the overdrive and intermediate servo bores inside the transmission case. As the bores wear, hydraulic pressure leaks past the servo pistons, leading to 2-3 flare, 3-5 flare, slipping, harsh engagement, and delayed or missing reverse. This issue is widely documented in owner complaints, transmission repair communities, and Ford service literature addressing shift flare and servo-related repairs.

What does P0745 mean on Ford?▼
P0745 stands for "Pressure Control Solenoid Malfunction." This transmission code indicates a problem with the pressure control solenoid (also called the line pressure or EPC solenoid), an electronically controlled valve that regulates the hydraulic fluid pressure inside the automatic transmission. The transmission computer uses this solenoid to set the right pressure for smooth, firm shifts, so when it detects an electrical fault or out-of-range performance, it sets this code. The result is often harsh, soft, or erratic shifting, and the transmission may drop into a protective limp mode. It generally points to an electrical or hydraulic issue with the solenoid itself or its control circuit. On Ford specifically, this code is documented across 1 model.
What causes P0745 on Ford vehicles?▼
Common causes on Ford: Failed or stuck pressure control (EPC) solenoid, Low or contaminated transmission fluid, Dirty fluid clogging or sticking the solenoid valve, Wiring or connector fault in the solenoid circuit, Internal valve body wear or leakage.
