DTC detection condition
P211900ETC ACTR-B1
(Throttle Actuator "A" Control Throttle Body Range/Performance)
ADiagnosis condition—
Signal (terminal)—
ThresholdElectric throttle control actuator does not function properly due to the return spring malfunction
Diagnosis delay time—
BDiagnosis condition—
Signal (terminal)—
ThresholdThrottle valve opening angle in fail-safe mode is not in specified range
Diagnosis delay time—
CDiagnosis condition—
Signal (terminal)—
ThresholdECM detects that the throttle valve is stuck open
Diagnosis delay time—
 
 
POSSIBLE CAUSE
Electric throttle control actuator
 
 
FAIL-SAFE
Engine operating condition in fail-safe mode
Fail safe modeVehicle behavior
Traveling control modeEngine output controlECM reduces the engine output, according to the rise in engine speed. This reduces the vehicle speed to encourage the driver to repair malfunction.
  • Driving at 70 km/h (44 MPH) or more is possible.
noteThis value is a reference value converted from engine power to vehicle speed. Actual power limitation value differs due to the malfunctioning part and driving condition.
Device fix mode
  • This mode fixes the electric IVT motor and the EVT control solenoid valve in the reference position.
  • The intake manifold runner control valve motor is turned OFF (intake manifold runner control valve opens).
  • A control signals is not transmitted to EGR volume control valve and the EGR volume control is deactivated.
Electric throttle control cancel mode ECM stops the electric throttle control actuator control, throttle valve is maintained at a fixed opening (approx. 5 degrees) by the return spring.
