P0547 — Exhaust gas temperature sensor signal error - Bank 1, Sensor 2

System: Powertrain  |  Type: Generic (OBD-II Standard)  |  Make: Generic

About P0547

P0547 is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P0547 is stored, the module has detected a bank-specific fault, meaning it applies only to one cylinder bank of a multi-bank engine; and a sensor-related fault — the reported value from the named sensor is out of spec.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P0547 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

Fault code P0547 is set when the vehicle's powertrain control module (PCM) detects an error in the signal from the exhaust gas temperature sensor located in Bank 1, Sensor 2. This sensor is responsible for measuring the temperature of the exhaust gases in the exhaust system and is crucial for effective emission control and engine performance management. The error could be due to a range of issues, including a faulty sensor, incorrect readings, or problems in the sensor circuit. Bank 1 typically refers to the side of the engine with the first cylinder, and Sensor 2 is usually located downstream...
