Diagnostic procedure
2 Disconnect PCM.
Is resistance between ground terminal at PCM
connector and body ground
less than 5.0
ohms ?
Yes Go to next step.
No Repair open ground circuit.
Reconnect PCM.
3 Check LPS PID value using WDS or equivalent.
Is LPS PID value okay?
(See
F–45 PCM INSPECTION .)
Yes Overhaul control valve body and repair or replace any
defective parts.
If problem remains, overhaul transaxle and repair or replace
any defective parts.

2. Go to No.7 “Fast idle/runs on” (See
F–198 NO.7 SLOW RETURN TO IDLE .)
5 No creep at all
DESCRIPTION
•
Either the transaxle is stuck in 3GR position, or there is clutch circuit slippage
POSSIBLE
CAUSE
•
Either transaxle is stuck in 3GR or 4GR position, or clutch circuit slippage due to a stuck 3–4 clutch is
stuck.
1. Clutch burned
•

Shift solenoid A malfunction
•
Shift solenoid B malfunction
•
Shift solenoid C malfunction

•
Body GND malfunction
•
Control valve body malfunction
2. Transaxle fixed in 3GR (Operation of fail-safe function)
•
Short or open circuit in wiring
•
Poor connection of connector
•
The electronic parts of output and input system is malfunction
3. The engine torque is not start
•
