P0544
Exhaust Gas Temperature Sensor Circuit (Bank 1 Sensor 1)
DTC P0544, sometimes indicated as P054400 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the engine idling stability causing exhaust gas temperature sensor circuit (bank 1 sensor 1).
This code means that the powertrain control module (PCM) has detected a problem with the exhaust gas temperature (EGT) sensor circuit for bank 1 sensor 1.
There are a few things that could cause this code:
- A problem with the wiring or connector for the EGT sensor
- A problem with the EGT sensor itself
- A problem with the PCM
If you have this code, the best thing to do is to have a qualified technician inspect the system and determine what is causing the problem.

2016 NISSAN TITAN with 62500.0 miles
Coming off a highway at around 50 mph the yellow check engine light came on and the engine started making a "popping" sound and jerking as if misfiring. Connected a code reader to truck and 5 issues were found. Engine codes P0544, P244D, P242D & P242C were listed stating "exhaust gas temp sensor" and "exhaust temp high for dpf" along with code P0204 "number 4 fuel injector circuit open". Had vehicle towed to dealership and the diesel mechanic stated the "graved connector f131 on cylinder #4 was at fault and that the connector "spread terminals were causing poor contact with injector". Stated the engine control harness (wiring harness), needed replacing. Vehicle had only ~62500 miles on it at the time.
