Murano 2.5 dci Error code P0546

[batamurano 0]

Please help, I have a Murano 2010. 2.5 dci (205,000 km) ... A month ago the check engine light came on and the error code is P0546 - Exhaust Gas Temperature Sensor, Sensor 1 Bank 1. After turning off the engine, the fan remains on for some 20-30 seconds, and only after a long drive. The exhaust temperature sensor has been replaced with a new one, but the computer shows the same error again. What could be the problem?

What kind of repair can fix the P0546 error?

Clear all error codes and perform a test drive of the car to find out if the error code appears again

Visual inspection and, if necessary, replacement of damaged exhaust gas temperature sensor wires and connectors

Check the resistance of the sensor and, if necessary, replace the sensor (the resistance must be at least 50 ohms)

In rare cases, replacement of the PCM (automatic transmission control module) or ECM (engine control module)

Additional comments to resolve the error P0546

It should be noted that one of the possible reasons for the appearance of this error code is the after-sales installation of a non-standard exhaust system instead of a catalytic converter, which leads to an increase in emissions. Before performing such a modification, you should read the local laws and find out if there are any restrictions regarding this procedure.

 

If this error occurs, carefully check all the wires and connectors of the sensor for loosening and corrosion.
