What is the diagnostic code for exhaust gas temperature sensor?
P0546 OBD-II Trouble Code: Exhaust Gas Temperature Sensor Circuit High Bank 1 Sensor 1. Cost of diagnosing the P0546 code. P0546 is a diagnostic trouble code (DTC) for “Exhaust Gas Temperature Sensor Circuit High Bank 1 Sensor 1”.
How are diagnostic trouble codes set on an ECM?
The electronic control units (ECUs) that communicate on the SAE J1939 data link, communicate according to the SAE J1587 standard. The diagnostic trouble codes (DTCs) set by the ECUs contain information that is described by the following abbreviations.
What is the DTC code for exhaust gas?
P0546 is a diagnostic trouble code (DTC) for “Exhaust Gas Temperature Sensor Circuit High Bank 1 Sensor 1”.
How does the engine control module ( ECM ) work?
The ECM takes the information from the engine’s various sensors, and uses that information to calculate and tune engine spark and fuel for maximum power and efficiency. The ECM plays a crucial role in newer vehicles, where many (if not all) of the essential functions of the car are controlled by the ECM.
What is the diagnostic code for exhaust gas temperature?
P2031 is a diagnostic trouble code (DTC) for “Exhaust Gas Temperature (EGT) Sensor Circuit Bank 1 Sensor 2”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
The electronic control units (ECUs) that communicate on the SAE J1939 data link, communicate according to the SAE J1587 standard. The diagnostic trouble codes (DTCs) set by the ECUs contain information that is described by the following abbreviations.
What is the code for an EGT sensor fault?
The Check Engine Light will be illuminated and the code for a fault in the EGT sensor circuit will be set in the ECM. The engine may run too rich or lean, depending on manufacturer’s failure strategy. The failure mode will depend on other symptoms encountered. The exhaust may be leaking before the sensor.
Where is the exhaust gas temperature sensor located?
This is a generic powertrain code, which means it covers all makes/models, 1996-newer. However, specific troubleshooting steps will vary depending on the vehicle. This diagnostic trouble code (DTC) P0546 refers to the condition of the EGT (exhaust gas temperature) sensor located in the “up” pipe forward of the catalytic converter.
