P0547 Exhaust Gas Temperature Sensor Circuit Bank 2 Sensor 1

Definition: This code indicates a malfunction in the exhaust gas temperature sensor circuit for bank 2, sensor 1. The sensor is responsible for monitoring the temperature of the exhaust gases and ensuring they are within optimal range.

P0548 Exhaust Gas Temperature Sensor Circuit Low Bank 2 Sensor 1

Definition: This code signifies that the exhaust gas temperature sensor circuit for bank 2, sensor 1 has detected a lower than expected voltage signal, indicating a possible short or open circuit.

P0549 Exhaust Gas Temperature Sensor Circuit High Bank 2 Sensor 1

Definition: This code means that the exhaust gas temperature sensor circuit for bank 2, sensor 1 has detected a higher than expected voltage signal, which may suggest an issue with the wiring or connector.

P0550 Power Steering Pressure Sensor Circuit Malfunction

Definition: Although not directly related to P0547, this code refers to a problem with the power steering pressure sensor circuit. It indicates that there is an issue with how the vehicle’s computer interprets signals from this particular sensor.

P0556 Brake Booster Pressure Sensor Circuit Range/Performance

Definition: Again unrelated to P0547, this code points to a performance issue within the brake booster pressure sensor circuit. It suggests that there might be inconsistencies in how pressure readings are being relayed to the vehicle’s control module.

p0547 – Exhaust Gas Temperature Sensor Circuit Bank 2 Sensor 1

Severity: Moderate

Common Causes

P0547 – Exhaust Gas Temperature Sensor Circuit Bank 2 Sensor 1/2

Description: The Powertrain Control Module (PCM) detects a voltage signal from the exhaust gas temperature sensor circuit in bank 2, sensor 1 that is higher than normal.

Common Causes:

• Faulty exhaust gas temperature sensor
• Wiring or connector issues in the exhaust gas temperature sensor circuit
• Exhaust leaks near the sensor
• Engine running too rich or lean

 

Common Misdiagnosis

OBD2 Code: P0547

Description: Exhaust Gas Temperature Sensor Circuit Bank 2 Sensor 1

Common Misdiagnosis: Replacing the exhaust gas temperature sensor without checking for wiring issues or connector problems.

 

Common Diagnostic Steps

OBD2 Code: P0547

Description: Exhaust Gas Temperature Sensor Circuit Bank 2 Sensor 1

Common Diagnostic Steps:

• Verify the code using an OBD2 scanner and clear it to see if it returns.
• Inspect the exhaust gas temperature sensor wiring for damage, disconnection, or corrosion.
• Check the sensor connector for secure connection and any signs of wear or damage.
• Test the exhaust gas temperature sensor resistance with a multimeter to ensure it is within manufacturer specifications.
• Examine the exhaust system for leaks or blockages that could affect sensor readings.
• If available, use a scan tool to monitor live data from the exhaust gas temperature sensor to check for abnormal readings.
• If necessary, replace the faulty exhaust gas temperature sensor with a new one and retest.
