DTC DETECTION LOGIC
DTCM.U.T.-III SE screen terms
(Trouble diagnosis content)
DTC detection condition
P044C00EGR SENSOR C
(EGR sensor C circuit low)
Diagnosis conditionIgnition switch ON
Signal (terminal)EGR volume control valve signal
ThresholdECM detects the following status continuously for 5 seconds or more:
A voltage signal transmitted from the EGR volume control valve position sensor shows too low.
Diagnosis delay time5 seconds or more
 
 
POSSIBLE CAUSE
  • Harness or connectors
    (EGR volume control valve position sensor circuit is open or shorted.)
  • EGR volume control valve
 
 
FAIL-SAFE
Engine operating condition in fail-safe mode
Fail safe modeVehicle behavior
Traveling control modeAccelerator angle variation controlECM controls the accelerator pedal depression speed to make it slower than actual speed. This causes a drop in accelerating performance and encourages the driver to repair malfunction.
noteECM does not control the accelerator pedal releasing speed.
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.
 
 
DTC Confirmation Procedure
1.PRECONDITIONING

2.PERFORM DTC CONFIRMATION PROCEDURE
  1. Turn ignition switch ON and wait at least 5 seconds.
  2. Check 1st trip DTC.
Is 1st trip DTC detected?
Proceed to DTC Diagnosis Procedure.
