Changed egt sensor but now saying po545 fault

If it ws mine, I would check the error code first with my OBD reader.

locate the exhaust pipe, you are probably referring to the EGT located just behind the catalytic converter

code p 2032 refers to exhaust gas temperature (EGT)sensor 2 bank 1---circuit low===causes --wiring short to ground---EGT sensor

code p2032 refers to exhaust gas temperature (EGT) sensor 2 bank 1 --circuit low===causes --wiring short to ground--EGT sensor

replace the sensor ensuring that you use the correct tool so as not to damage the wires of the new sensor.

code p2033 refers to exhaust gas temperature (EGT) sensor 2 bank 1 circuit high === causes wiring short to ground --EGT sensor . check the wiring for shorted / broken wires and replace the sensor . If there is no problem with the sensor or the new sensor fails early I would be checking the fuel settings on the pump ( pump timing and cc ratings ) as a hot diesel exhaust indicates over fuelling or pump timing too far advanced.

THERE ARE SEVERAL SENSORS:

EXHAUST GAS TEMPERATURE (EGT) SENSOR
EXHAUST PRESSURE (EP) SENSOR
DIESEL PARTICULATE FILTER PRESSURE SENSOR

HOPE THIS INFORMATION HELPS

your EGT sensor might be shot...or you have a vacuum hose that came undone from your intake...

check for continuity with a meter
