P040D - EGR TEMPERATURE SENSOR A CIRCUIT HIGH
| Description: | This DTC sets when the exhaust gas recirculation temperature bank 1, sensor 1 (EGRT11) (Transit) or the exhaust gas recirculation temperature bank 1, sensor 2 (EGRT12) (all others) temperature is greater than a calibrated limit for a specified amount of time. When the EGRT11 (Transit) or the EGRT12 (all others) is greater than a calibrated threshold, an increment counter advances for that drive cycle. | ||

| Diagnostic Aids: | The presence of this DTC may indicate that the vehicle is operating in derate mode and may experience a loss of power. After repair, the vehicle may still display a system warning message. Drive the vehicle until the system warning message has cleared from the instrument cluster message center. This DTC sets when the EGRT12 sensor signal voltage is greater than 4.9 volts for greater than 3 seconds. |
