Pinpoint Test RC: Exhaust Gas Temperature 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.
WARNING:
Manual regeneration of the particulate filter causes the exhaust gas to quickly get very hot. Initiate a manual regeneration only when the vehicle is on the ground with the area around the tailpipe free of people, obstructions, foreign material or other items. Failure to follow these instructions may result in serious personal injury.
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.
Refer to ELECTRONIC ENGINE CONTROLS - 3.0L DIESEL 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 P0544:00 | Exhaust Gas Temperature Sensor Circuit - Bank 1 Sensor 1: No Sub Type Information | Sets when the PCM detects the exhaust gas temperature bank 1, sensor 1 sensor temperature does not correlate to the modeled temperature of 170°C (338°F) after 5 minutes of driving, following a 6 hour soak. The PCM monitors the operation of the exhaust gas temperature bank 1, sensor 1 to determine if the exhaust gas temperature bank 1, sensor 1 sensor responds to the increase in temperature of the exhaust gas during vehicle operation. The PCM then compares the measured temperature to a modeled value. Monitor the EGT11 PID between KOEO and KOER for an indication of a concern. |
| PCM P0545:00 | Exhaust Gas Temperature Sensor Circuit Low - Bank 1 Sensor 1: No Sub Type Information | Sets when the PCM detects the exhaust gas temperature bank 1, sensor 1 voltage is less than 0.10 volt for greater than 15 seconds. An EGT11_V PID value less than 0.10 volt indicates a concern. |
| PCM P0546:00 | Exhaust Gas Temperature Sensor Circuit High - Bank 1 Sensor 1: No Sub Type Information | Sets when the PCM detects the exhaust gas temperature bank 1, sensor 1 voltage is greater than 4.90 volts for greater than 15 seconds.
