P0745 on Nissan
Pressure Control Solenoid Malfunction
P0745 on Nissan vehicles indicates pressure control solenoid malfunction. Au7o has documented this code across 1 Nissan model — most commonly on Frontier. 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 Nissan 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

Nissan Frontier(1 issue)
- RE5R05A 5-Speed Valve Body and Integrated TCM Solenoid Failure Causing Limp Mode2005-2019
The Jatco RE5R05A five-speed automatic used in the second-generation Frontier carries its transmission control module bolted directly to the valve body, submerged in hot ATF. That packaging is the weak point: sustained heat cycling and vibration crack solder joints and kill solenoid drivers, while the shift solenoids themselves are delicate and intolerant of any contamination. Owners report slipping between gears, delayed or flared upshifts, refusal to shift above a certain gear, and the transmission dropping into a fixed-gear limp mode. This is documented as a failure in its own right and is distinct from - though badly aggravated by - the coolant-into-ATF radiator failure this platform is also known for, since the resulting gel jams the solenoid plungers and shorts the solenoid wiring. Diagnosis is often mistaken for whole-transmission failure when only the valve body and TCM have gone.

What does P0745 mean on Nissan?▼
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 Nissan specifically, this code is documented across 1 model.
What causes P0745 on Nissan vehicles?▼
Common causes on Nissan: 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. Specific causes vary by model and year — see the per-model sections below.
