DTC P0755 SHIFT SOLENOID VALVE B
Description
INFOID:0000000001694364
Shift solenoid valves A and B are turned ON or OFF by the TCM in response to signals sent from the PNP
switch, vehicle speed and ECM (throttle opening). Gears will then be shifted to the optimum position.
CONSULT-III Reference Value in Data Monitor Mode
INFOID:0000000001694365
Remarks: Specification data are reference values.
On Board Diagnosis Logic
INFOID:0000000001694366
• This is an OBD self-diagnostic item.
• Diagnostic trouble code “P0755 SHIFT SOLENOID/V B” with CONSULT-III or 5th judgement flicker without
CONSULT-III is detected when TCM detects an improper voltage drop when it tries to operate the solenoid
valve.
Possible Cause
INFOID:0000000001694367
• Harness or connector
(The solenoid circuit is open or shorted.)
• Shift solenoid valve B
DTC Confirmation Procedure
INFOID:0000000001694368
CAUTION:
• Always drive vehicle at a safe speed.
• If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait at
least 10 seconds before continuing.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
1.
Turn ignition switch ON and select “DATA MONITOR” mode for “A/T” with CONSULT-III.
2.
Touch “START”.
3.
Start engine.
4.
Drive vehicle in D position and allow the transaxle to shift 1

→
3 (“GEAR”).
5.
If the check result is NG, go to
WITH GST
Follow the procedure “WITH CONSULT-III”.
WITHOUT CONSULT-III
1.
Start engine.
2.
Drive vehicle in D
