TM-148 < COMPONENT DIAGNOSIS > [CVT: RE0F09B] P0745 LINE PRESSURE SOLENOID VALVE P0745 LINE PRESSURE SOLENOID VALVE Description INFOID:0000000004201703 The pressure control solenoid valve A (line pressure solenoid valve) regulates the oil pump discharge pres- sure to suit the driving condition in response to a signal sent from the TCM. DTC Logic INFOID:0000000004201704 DTC DETECTION LOGIC DTC CONFIRMATION PROCEDURE NOTE: If “DTC CONFIRMATION PROCEDURE” has been previously performed, always turn ignition switch OFF. Then wait at least 10 seconds before performing the next test. 1. CHECK DTC DETECTION With CONSULT-III 1. Turn ignition switch ON. 2. Start engine and wait at least 5 seconds. 3. Perform “SELF-DIAG RESULTS” mode for “TRANSMISSION”. With GST Follow the procedure “With CONSULT-III”. YES >> Go to NO >> Check intermittent incident. Refer to GI-42, "Intermittent Incident" . Diagnosis Procedure INFOID:0000000004201705 1. CHECK PRESSURE CONTROL SOLENOID VALVE A (LINE PRESSURE SOLENOID VALVE) CIRCUIT 1. Turn ignition switch OFF. 2. Disconnect TCM harness connector. 3. Check resistance between TCM harness connector F16 terminal 40 and ground. Is the inspection result normal? YES >> GO TO 5. NO >> GO TO 2. 2. CHECK HARNESS BETWEEN TCM AND CVT UNIT [PRESSURE CONTROL SOLENOID VALVE A (LINE PRESSURE SOLENOID VALVE)] (PART 1) DTC Item (CONSULT-III screen term) Malfunction is detected when... Possible cause P0745 L/PRESS SOL/CIRC • Normal voltage not applied to solenoid due to open or short circuit. • TCM detects as irregular by comparing target value with monitor value. • Harness or connectors (Solenoid circuit is open or shorted.) • Pressure control solenoid valve A (line pressure solenoid valve) TCM harness connector Ground Resistance (Ap- prox.) Connector Terminal F16 40 3.0 – 9.0 Ω AWDIA0120ZZ |
