Frequently Asked Questions

What does error code P0547 mean?
P0547 indicates a circuit malfunction in the Exhaust Gas Temperature (EGT) sensor for bank 2, sensor 1. This sensor monitors exhaust temperature to protect emissions components.
Can I drive with a P0547 code?
Yes, but it may reduce fuel efficiency and increase emissions. Continued driving with a faulty sensor can cause damage to the catalytic converter or turbocharger over time.
Where is the exhaust gas temperature sensor located?
Bank 2 sensor 1 is typically located on the exhaust manifold or downpipe near the engine, on the cylinder bank opposite of bank 1. Refer to your vehicle's service manual for exact location.
How much does it cost to fix code P0547?
DIY cost is about $50-$150 for the sensor and anti-seize compound. Professional repair ranges from $150 to $400 including labor and parts.
Can a bad EGT sensor cause other codes?
Yes, a faulty EGT sensor may trigger related codes such as P0546 (sensor high input) or P0548 (sensor low input).
