TROUBLE DIAGNOSES FOR SYMPTOMS
Engine Speed Does Not Return To Idle (Light Braking D
4→ D3 )ECS004VG
SYMPTOM:
●Engine speed does not smoothly return to idle when A/T shifts from D4 to D3 .
●Vehicle does not decelerate by engine brake when turning overdrive control switch OFF.
●Vehicle does not decelerate by engine brake when shifting A/T from “D” to “2” position.
1. CHECK SELF-DIAGNOSTIC RESULTS
Does self-diagnosis show damage to overrun clutch solenoid valve
circuit after cruise test?
Ye s o r N O
Yes >> Check overrun clutch solenoid valve circuit. Refer to AT-
377, "OVERRUN CLUTCH SOLENOID VALVE"
(Except for Euro-OBD).
No >> GO TO 2.
2. CHECK ACCELERATOR PEDAL POSITION (APP) SENSOR
Check accelerator pedal position (APP) sensor. Refer to AT- 3 6 2 ,
"ACCELE RATOR PEDAL POSITION (APP) SENSOR" —Except for
Euro-OBD.
OK or NG
OK >> GO TO 3.
NG >> Repair or replace accelerator pedal position (APP) sen-
sor.
3. CHECK A/T FLUID CONDITION
1. Remove oil pan.
2. Check A/T fluid condition.
OK or NG
OK >> GO TO 4.
NG >> GO TO 6.

REMOVAL AND INSTALLATION
3. Tighten belts fixing transaxle.
4. Reinstall any part removed.
5. Adjust control cable. Refer to AT- 4 1 6 , "
Control Cable Adjust-
ment" .
6. Check continuity of PNP switch. Refer to AT- 11 0 , "
DTC P0705
PARK/NEUTRAL POSITION (PNP) SWITCH" .
7. Refill transaxle with ATF and check fluid level.
8. Move selector lever through all positions to be sure that tran-
saxle operates correctly. With parking brake applied, idle
engine. Move selector lever through “N” to “D”, to “2”, to “1” and
“R” positions. A slight shock should be felt through the hand
gripping the selector each time the transaxle is shifted.
9. Perform road test. Refer to AT-68, "
Road Test" .
