→
D
4
ECS009A4
SYMPTOM:
●
A/T does not shift from D
3
to D
4
at the specified speed.
●
A/T must be warm before D
3
to D
4
shift will occur.
1.
CHECK SYMPTOM
Are “7. Vehicle Does Not Creep Forward In D, 3, 2 or 1 Position” and “8. Vehicle Cannot Be Started From D
1
”
OK?
Yes or No
Yes >> GO TO 2.
No >> Go to AT-228, "7. Vehicle Does Not Creep Forward in D, 3, 2 or 1 Position" and AT-231, "8. Vehi-
cle Cannot Be Started From D
1
" .
2.
CHECK SELF-DIAGNOSTIC RESULTS
With CONSULT-II
Does self-diagnosis, after cruise test, show damage to any of the fol-
lowing circuits?
●
Park/neutral position (PNP) switch
●
Overdrive control switch
●
A/T fluid temperature sensor
●
Vehicle speed sensor·A/T (revolution sensor)
●
Shift solenoid valve A or B
●
Vehicle speed sensor·MTR
Yes or No
Yes >> Check damaged circuit. Refer to AT-110, "DTC P0705
PARK/NEUTRAL POSITION SWITCH" , AT-116, "DTC
P0710 A/T FLUID TEMPERATURE SENSOR CIRCUIT"
, AT-122, "DTC P0720 VEHICLE SPEED SENSOR·A/T
(REVOLUTION SENSOR)" , AT-172, "DTC P0750
SHIFT SOLENOID VALVE A" , AT-177, "DTC P0755
SHIFT SOLENOID VALVE B" or AT-201, "DTC VEHI-
CLE SPEED SENSOR MTR" .
No >> GO TO 3.
3.
CHECK THROTTLE POSITION SENSOR [ACCELERATOR PEDAL POSITION (APP) SENSOR]
Check throttle position sensor [accelerator pedal position (APP) sen-
sor]. Refer to
EC-206, "DTC P0122, P0123 TP SENSOR" and EC-
521, "DTC P2122, P2123 APP SENSOR" .
OK or NG
OK >> GO TO 4.
NG >> Repair or replace throttle position sensor [accelerator
pedal position (APP) sensor].
