5 INSPECT LINE PRESSURE
•
Start engine.
•
Measure line pressure.
Specification
Idle: 330—470 kPa {3.4—4.7 kgf/cm
2
, 49—66
psi}
Stall: 1,200—1,360 kPa {12.3—13.8 kgf/cm
2
,
175—196 psi}
•
Is line pressure within specification?
(See K–6 Line Pressure Test .)
Yes Go to next step.
No
•
All ranges: Replace oil pump or control valve body, then
go to Step 7.
•
Any ranges: Replace ATX, then go to Step 7.
(See K–29 AUTOMATIC TRANSAXLE REMOVAL/
INSTALLATION .)
(See ATX Workshop Manual FN4A-EL (9999-95-FN4A-
99).)
6 CHECK OPERATION OF EACH VALVE AND
EACH SPRING
•
Turn ignition key to OFF.
•
Remove control valve body.
•
Disassemble control valve body.
•
Is each valve operation okay and is return
spring okay?
(See K–34 CONTROL VALVE BODY REMOVAL ,
K–35 CONTROL VALVE BODY INSTALLATION .)
(See ATX Workshop Manual FN4A-EL (9999-95-
FN4A-99).)
Yes Replace ATX, then go to next step.
(See K–29 AUTOMATIC TRANSAXLE REMOVAL/
INSTALLATION .)
(See ATX Workshop Manual FN4A-EL (9999-95-FN4A-
99).)
No Repair or replace shift valve and return spring, then go to
next step.

STEP INSPECTION ACTION
DTC P0763 Shift solenoid C malfunction (electrical)
DETECTION
CONDITION
•
If PCM detects either of following conditions, PCM determines that shift solenoid C circuit has a
malfunction:
— Shift solenoid C voltage is stuck at
B+ after engine start.
— Shift solenoid C voltage is stuck at 0 V after engine start.
Diagnostic support note:
•
This is a continuous monitor (CCM).
•
MIL illuminates if PCM detects the above malfunction conditions during first drive cycle.
•
PENDING CODE is not available.
•
FREEZE FRAME DATA is available.
•
HOLD indicator light flashes.
•
DTC is stored in the PCM memory.
POSSIBLE
CAUSE
•
Shift solenoid C malfunction
•
Short to ground between ATX connector terminal G and PCM terminal 4Y
•
Short to power between ATX connector terminal G and PCM terminal 4Y
•
Open circuit between shift solenoid C terminal B and ATX connector terminal G
•
Open circuit between ATX connector terminal G and PCM terminal 4Y
•
Open circuit between shift solenoid C terminal A and body ground point
•
Damaged connector between shift solenoid C and PCM.
•
PCM malfunction.
