Question about Renault Megane
P0745 - Pressure Control Solenoid Malfunction
- Low transmission fluid level
- Dirty transmission fluid
- Faulty line pressure solenoid valve
- Line pressure solenoid valve harness is open or shorted
- Line pressure solenoid valve circuit poor electrical connection Help with this
When the a transmission solenoid is malfunction, in most cases the problem is not the electrical part of the solenoid; the problem is foreign material obstructing the mechanical function of the solenoid or the flow of the fluid through the transmission valve body. If the transmission fluid is very dirty, it is recommend changing the transmission fluid and if possible removing the transmission pan for further diagnosis. Excessive debris or metal particles on the transmission pan could be an indication that there is a transmission mechanical failure and that the transmission will need to be rebuilt or replaced.
Help with this
When is the code detected?
The P0745 is detected when TCM detects an improper voltage drop when it tries to operate the solenoid valve.
- Engine Light ON (or Service Engine Soon Warning Light)
- Transmission shift shock
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).

smal evap leak detected....very common check your fuel cap make sure it't tightened at least three clicks-check the o-ring of the cap as this will
cause a leak as well. drive vehicle the code will clear it's self if it odes not go away after 1 week of continuos driving it may have a larger leak
