O R C
P242C X
Exhaust Gas Temperature
Sensor Circuit Low
Bank 1 Sensor 3
This error occurs when the EGT3 sensor temperature
signal is higher (lower voltage signal) than a maximum
probable temperature, indicating a short to ground.
P242D X
Exhaust Gas Temperature
Sensor Circuit High
Bank 1 Sensor 3
This error occurs when the EGT3 sensor temperature signal
is lower (higher voltage signal) than a minimum probable
temperature, indicating an open circuit or a short to power.
P242E X
Exhaust Gas Temperature
Sensor Circuit Intermittent
Bank 1 Sensor 3
This error occurs if an intermittent signal from the
exhaust gas temperature sensor is detected.
P242F REGEN
Diesel Particulate Filter
Restriction - Ash Accumulation
This error occurs if excessively high exhaust
pressures are detected after a regen cycle.
P244A REGEN
Diesel Particulate Filter
Differential Pressure Too Low
This error occurs if an expected pressure drop through the
DPF is lower than the specified value following a regeneration
cycle (based on the concept of observed pressure differential).
P244C X X X
Exhaust Temperature
too low for Particulate
Filter Regeneration
This error occurs if the exhaust temperature is too low to
perform a regen cycle of the diesel particulate filter.
P244D REGEN
Exhaust Temperature
too high for Particulate
Filter Regeneration
This error occurs if exhaust temperatures are too high to
perform a regen cycle of the diesel particulate filter.
P2453 X
X
KO
Diesel Particulate Filter
Differential Pressure Sensor
Circuit Range/Performance
This error occurs if the differential pressure of
the diesel particulate filter reads a constant
value while the engine is running.
P2454 X
Diesel Particulate Filter
Differential Pressure
Sensor Circuit Low
This error occurs if a short to ground is detected in the
diesel particulate filter differential pressure sensor circuit.
P2455 X
Diesel Particulate Filter
Differential Pressure
Sensor Circuit High
This error occurs if a short to power occurs in the diesel
particulate filter differential pressure sensor circuit.
P2456 X
Diesel Particulate Filter
Differential Pressure Sensor
Circuit Intermittent/Erratic
This error occurs if the signal from the diesel particulate
filter differential pressure sensor to the PCM is unreadable.
P2457 X X
Exhaust Gas Recirculation
Cooler System Performance
This error occurs if the EGR cooler temperature
sensor reading is above a maximum threshold
for a predetermined period of time.

Turbocharger Boost Control
Position Sensor A Circuit
Range/Performance
This error occurs when the difference between the
turbocharger actuator commanded duty cycle and
the feed forward commanded duty cycle is less than
the threshold value for the given engine speed and
engine load for a predetermined period of time.

System error
P2610 X
ECM/PCM Internal Engine
Off Timer Performance
This error occurs when the engine off timer does not
correlate to the PCM’s internal timer (compared while
the engine is running), if the engine off time does not
correspond with the measured ECT temperature variation
between the last engine stop and the next engine
start, or when the engine off timer is defective.
U0073 X X X
Control Module
Communication Bus A Off
This error occurs if a fault in the CAN
communication is detected.
U0101 X X X Lost Communication with TCM
This error occurs is the CAN data communication
is interrupted between the PCM and the TCM.
