When does the PCM set the code p0745?
The code P0745 is set by the PCM when the Pressure Control Solenoid “A” is experiencing a general malfunction. Example of a transmission pressure control solenoid: What is the severity of this DTC?
What causes a p0745 transmission to malfunction?
Causes for this P0745 transmission code may include: 1 Defective Pressure Control Solenoid 2 Dirty or contaminated fluid 3 Dirty or clogged transmission filter 4 Defective Transmission Pump 5 Defective Transmission Valve Body 6 Restricted hydraulic passages 7 Corroded or damaged connector 8 Faulty or damaged wiring 9 Faulty PCM
What are the trouble codes for an a solenoid?
The trouble codes related to the “A” solenoid are codes P0745, P0746, P0747, P0748 and P0749. The code set is based on the specific malfunction that alerts the PCM and illuminates the Check Engine Light.
How does the PCM control the pressure solenoids?
Based on the signals from associated devices monitoring the speed of the vehicle, the PCM controls the pressure solenoids to direct fluid at the appropriate pressure to various hydraulic circuits that change the transmission gear ratio at the correct time.
The code P0745 is set by the PCM when the Pressure Control Solenoid “A” is experiencing a general malfunction. Example of a transmission pressure control solenoid: What is the severity of this DTC?
What causes a pressure solenoid code of p0745?
The most common causes for a P0745 code include a defective valve body or pressure solenoid. Your vehicle may also suffer from poor or defective wiring on your pressure solenoid.
Is there a problem with the p0745 OBD-II trouble code?
Although generic, the exact repair steps may vary depending on year, make, model and powertrain configuration. When the P0745 OBD-II trouble code is set, the Powertrain Control Module (PCM) has detected a problem with the Transmission Pressure Control Solenoid “A”.
When does DTC p0745 set in a transmission?
DTC P0745 sets when the PCM/TCM has detected an problem in the electronic pressure control solenoid circuit. Computer controlled automatic transmissions use variable amounts of hydraulic pressure to provide shifting and TCC (torque converter clutch) operation. Figure 1 shows a simplified wiring diagram of a TFT circuit.
What does code p0745 mean in hydraulic pump?
What Does Code P0745 Mean? The transmission or transaxle hydraulic pump pressure is controlled (See above animation) by a PWM (pulse-width-modulated) solenoid called: TFP (Transmission Fluid Pressure) solenoid, EPC (Electronic Pressure Control) or PCS (Pressure Control Solenoid), VFS (Variable force solenoid), or just FM (Force Motor).

What are the possible causes of p1762 Dodge?
P1762 DODGE Possible Causes 1 Internal transmission failure 2 Faulty Governor Pressure Sensor 3 Governor Pressure Sensor harness open or shorted 4 Governor Pressure Sensor circuit poor electrical connection
Causes for this P0745 transmission code may include: 1 Defective Pressure Control Solenoid 2 Dirty or contaminated fluid 3 Dirty or clogged transmission filter 4 Defective Transmission Pump 5 Defective Transmission Valve Body 6 Restricted hydraulic passages 7 Corroded or damaged connector 8 Faulty or damaged wiring 9 Faulty PCM
How much does it cost to repair Nissan p0745?
The cost of diagnosing the P0745 NISSAN code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type.
How does the line pressure solenoid valve work?
Opening the exhaust port decreases the output fluid pressure regulated by the PC solenoid valve, which ultimately decreases line pressure. The line pressure solenoid valve regulates the oil pump discharge pressure to suit the driving condition in response to a signal sent from the Transmission Control Module (TCM). P0745 NISSAN More Information
When to use pressure control solenoid code p0746?
The code P0746 is set by the PCM when the Pressure Control Solenoid “A” is not functioning properly or stuck in the “Off” position. Example of a transmission pressure control solenoid: What is the severity of this DTC?
What is the trouble code for transmission solenoid a?
When the P0746 OBD-II trouble code is set, the Powertrain Control Module (PCM) has detected a problem with the Transmission Pressure Control Solenoid “A”. Most automatic transmissions incorporate at least three solenoids that are solenoid A, B and C. The trouble codes related to the “A” solenoid are codes P0745, P0746, P0747, P0748 and P0749.
