P0545 Dodge Code - Exhaust Gas Temperature Sensor Circuit Low Bank 1 Sensor 1

Quick Answer

The Powertrain Control Module (PCM) continuously monitors the Exhaust Gas Temperature Sensor (EGTS) for proper circuit continuity and out of range high values. Common causes include Faulty Exhaust Gas Temperature Sensor (EGTS) Bank 1 Sensor 1, Exhaust Gas Temperature Sensor Bank 1 Sensor 1 harness is open or shorted, Exhaust Gas Temperature Sensor Bank 1 Sensor 1 circuit poor electrical connection. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P0545 Dodge Description

The Powertrain Control Module (PCM) continuously monitors the Exhaust Gas Temperature Sensor (EGTS) for proper circuit continuity and out of range high values. The EGTS is located in front of the Diesel Oxidation Catalyst (DOC) and/or in front of the Diesel Particulate Filter (DPF). The EGTS detects exhaust gas temperature and converts it into a voltage and feeds back to the PCM with the voltage signal in order to control engine conditions to effectively reduce emissions. The PCM sets the P0545 OBDII code when the Exhaust Gas Temperature Sensor is out of factory specifications.

Discuss the causes and fixes for P0545 Dodge OBDII Code

  • My GASOLINE 98 Didge B2500 with 318 "Y" engine is throwing a P0545 code. My vehicle is NOT a diesel engine, yet the article only references diesel engines.

  • Unfortunately I haven't had that problem before, but I check the factory service manual and the manual have the P0545 code description as Exhaust Gas Temperature Sensor Circuit Low Bank 1 Sensor 1, but it recommends to inspect the A/C Clutch Relay. According to a national database of repairs for your model year, there are mixed results, some say the problem is the sensor and some the A/C Clutch Relay.
    I recommend start by replacing the relay. The relay is cheap and easy to replace.

  • I already replaced the EGT (oxygen sensor, as Dodge refers to it) with no positive result, so I will check out the A/C clutch replay for a potential problem.

    Thank you for your rapid response.

  • Please let us know if that takes care of the problem.
