Nissan Rogue (T33) 2021-Present Service Manual: P044c Egr Volume Control Valve Position Sensor
DTC Description
DTC DETECTION LOGIC
| DTC |
CONSULT screen terms (Trouble diagnosis content) |
DTC detection condition | ||
| P044C | 00 |
EGR SENSOR C (EGR sensor C circuit low) |
Diagnosis condition | Ignition switch ON |
| Signal (terminal) | EGR volume control valve signal | |||
| Threshold |
ECM 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 time | 5 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
| Fail safe mode | Nissan Ariya Vehicle behavior | |
|---|---|---|
| Traveling control mode | Accelerator angle variation control |
ECM 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.
ECM does not control the accelerator pedal releasing speed. |
| Device fix mode |
