DTC P0745 LINE PRESSURE SOLENOID VALVE
PFP:31940
Description
UCS0033J
The line pressure solenoid valve regulates the oil pump discharge pressure to suit the driving condition in
response to a signal sent from the TCM.
The line pressure duty cycle value is not consistent when the closed throttle position signal is “ON”.
To confirm the line pressure duty cycle at low pressure, the accelerator (throttle) should be open until
the closed throttle position signal is “OFF”.
CONSULT-II Reference Value
UCS0033K
On Board Diagnosis Logic
UCS0033L
●
This is an OBD-II self-diagnostic item.
●
Diagnostic trouble code “P0745 L/PRESS SOL/CIRC” with CONSULT-II or 4th judgement flicker without
CONSULT-II is detected under the following conditions.
–
When TCM detects an improper voltage drop when it tries to operate the solenoid valve.
–
When TCM detects as irregular by comparing target value with monitor value.
Possible Cause
UCS0033M
●
Harness or connectors
(The solenoid circuit is open or shorted.)
●
