DTC P0755 SHIFT SOLENOID VALVE B
PFP:31940
DescriptionECS004S2
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
throttle position sensors. Gears will then be shifted to the optimum
position.

DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCE-
DURE” has been previously conducted, always turn ignition
switch “OFF” and wait at least 5 seconds before conducting the
next test.
After the repair, perform the following procedure to confirm the mal-
function is eliminated.
With CONSULT-II
1. Turn ignition switch “ON” and select “DATA MONITOR” mode for
“A/T” with CONSULT-II.
2. Check the following.
If the check result is NG, go to “DIAGNOSTIC PROCEDURE”,AT-206, "
Diagnostic Procedure".
If the check result is OK, go to following step.
3. Turn ignition switch “ON” and select “DATA MONITOR” mode for
“ENGINE” with CONSULT-II.
4. Start engine and maintain the following conditions for at least 3
consecutive seconds. Then release accelerator pedal com-
pletely.
VHCL SPEED SE: 10 km/h (6 MPH) or more
THRTL POS SEN: Approximately 3V or less
Selector lever: D position (OD “ON”)
If the check result is NG, go to “DIAGNOSTIC PROCEDURE”,
AT-206, "
Diagnostic Procedure".
If the check result is OK, go to following step.
5. Maintain the following conditions for at least 3 consecutive sec-
onds. Then release accelerator pedal completely.
VHCL SPEED SE: 10 km/h (6 MPH) or more
Accelerator pedal: Wide open throttle
Selector lever: D position (OD “ON”)
With GST
Follow the procedure “With CONSULT-II”.

Diagnostic Procedure
ECS004S8
1.CHECK DTC WITH ECM
Perform diagnostic test mode II (self-diagnostic results) for engine control.
Refer to EC-´´, “Malfunction Indicator Lamp (MIL)”.
OK or NG
OK (With CONSULT-II)>>GO TO 2
OK (Without CONSULT-II)>>GO TO 3
NG >> Check throttle position sensor circuit for engine control. Refer toEC-154, "
DTC P0121 APP SEN-
SOR".
2.CHECK INPUT SIGNAL (WITH CONSULT-II)
With CONSULT-II
1. Turn ignition switch to “ON” position.
(Do not start engine.)
2. Select “TCM INPUT SIGNALS” in “DATA MONITOR” mode for
“A/T” with CONSULT-II.
3. Read out the value of “THRTL POS SEN”.
OK or NG
OK >> GO TO 4
NG >> Check harness for short or open between ECM and
TCM regarding throttle position sensor circuit. (Main
harness)
