Code P0745 2002 Nissan Altima Sedan Description

The Pressure Control (PC) Solenoid Valve an electronic pressure regulator that controls transmission line pressure based on current flow through its coil windings. As current flow is increased, the magnetic field produced by the coil moves the solenoid’s plunger further away from the exhaust port. 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).

Discuss the causes and fixes for P0745 2002 Nissan Altima Sedan OBDII Code

  • I started having issues with the trans on my 02 2.5 altima 209k miles on vacation I got home research issue and I unplugged the drop resister to check the ohm's I drove it a few miles plugged it back in next trip I took SES lights pops on with P0745 & P1574 could me unplugging the drop resistor be the cause of both codes or one or ?
    I assume it caused the light but which one is the cause of issue
    Thanks wes

  • Yes, more than likely the code set by you disconnecting the resistor.

  • My car randomly started slamming every time my car shifted. we read the codes but personally they mean nothing to me. my friend said he thinks it could be this part but wouldn't know unless he looked at it and just hasn't found time. I'm wondering if you have to take the tranny apart to fix this part or if you can get to it without taking it apart?

  • Start by checking the transmission fluid level and condition. If the fluid is OK, then you may have a problem with the Line pressure solenoid valve, which is inside the transmission attached to the transmission valve body. Due to the age of your vehicle, I recommend having a transmission shop inspect the vehicle.
