Pinpoint Test WA: Exhaust Gas RECIRCULATION Temperature (EGRT) Sensor
WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Regeneration may occur during normal operation. During regeneration, diagnostic procedures may display biased values. If a regeneration occurs during diagnostic procedures, allow the process to complete before continuing diagnostics.
NOTE:
Refer to the appropriate Wiring Diagrams for schematic and connector information.
Normal Operation and Fault Conditions
Refer to the DTC Fault Trigger Conditions.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Condition |
|---|---|---|
| PCM P040B:00 | EGR Temperature Sensor "A" Circuit Range/Performance: No Sub Type Information | Sets when the PCM detects the EGRT bank 1, sensor 2 temperature is less than or greater than a calibrated limit for a specified amount of time. When the change in theEGRT12 is less than or greater than a calibrated threshold, an increment counter advances for that drive cycle. The presence of this DTC may indicate 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 message center. |
| PCM P040C:00 | EGR Temperature Sensor "A" Circuit Low: No Sub Type Information | Sets when the PCM detects the EGRT bank 1, sensor 2 temperature is less than a calibrated limit for a specified amount of time (when the EGRT12 sensor signal voltage is less than 0.1 volt for greater than 3 seconds). When the EGRT12 is less than a calibrated threshold, an increment counter advances for that drive cycle. The presence of this DTC may indicate 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 IPC message center. |
| PCM P041B:00 | EGR Temperature Sensor "B" Circuit Range/Performance: No Sub Type Information | Sets when the PCM detects the EGRT bank 1, sensor 1 temperature is less than or greater than a calibrated limit for a specified amount of time. When the change in the EGRT11 is less than or greater than a calibrated threshold, an increment counter advances for that drive cycle. The presence of this DTC may indicate 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 message center. |
| PCM P041C:00 | EGR Temperature Sensor "B" Circuit Low: No Sub Type Information | Sets when the PCM detects the EGRT bank 1, sensor 2 temperature is greater than a calibrated limit for a specified amount of time. When the change in the EGRT12 is less than or greater than a calibrated threshold, an increment counter advances for that drive cycle. The presence of this DTC may indicate 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 message center. |
| PCM P041D:00 | EGR Temperature Sensor "B" Circuit High: No Sub Type Information | Sets when the PCM detects the EGRT bank 1, sensor 2 temperature is less than a calibrated limit for a specified amount of time. When the EGRT12 is greater than a calibrated threshold, an increment counter advances for that drive cycle. The presence of this DTC may indicate 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 message center. |
