DTC P061F: Internal Control Module Throttle Actuator Controller Performance Problem
.
TECHNICAL DESCRIPTION
• To judge whether fail-safe control can be per-
formed, check that power supply to the throttle
actuator control motor circuit can be stopped by
turning the throttle actuator control motor relay to
OFF position momentarily.
.
DTC SET CONDITIONS
Check Condition
• Ignition switch is "ON" position.
Judgment Criterion
• Power supply to the throttle actuator control
motor cannot be shut down (though power supply
