P0676 X X X Cylinder 6 Glow Plug Circuit
This error occurs if the current for an individual glowplug
is either lower than the minimum current threshold
or higher than the maximum current threshold.
An open is a current level less
than 4 amps and a shorted
current level is above 60 amps.
Glow Plug on time > 8.5 sec
Wiring, Glow Plug, GPCM
P0677 X X X Cylinder 7 Glow Plug Circuit
This error occurs if the current for an individual glowplug
is either lower than the minimum current threshold
or higher than the maximum current threshold.
An open is a current level less
than 4 amps and a shorted
current level is above 60 amps.
Glow Plug on time > 8.5 sec
Wiring, Glow Plug, GPCM
P0678 X X X Cylinder 8 Glow Plug Circuit
This error occurs if the current for an individual glowplug
is either lower than the minimum current threshold
or higher than the maximum current threshold.
An open is a current level less
than 4 amps and a shorted
current level is above 60 amps.
Glow Plug on time > 8.5 sec
Wiring, Glow Plug, GPCM
P0684 X X X
Glow Plug Control Module
to PCM Communication
Circuit Range/Performance
This error occurs when the pass/fail status information
signal, sent by the GPCM to the PCM, is consistantly high,
consistantly low, or the period of the signal is out of range.
GP active >5 sec Wiring, GPCM, PCM
P0691 X Fan 1 Control Circuit Low
P0692 X Fan 1 Control Circuit High
P0703 X Brake Switch B Input Circuit
This error occurs when the brake switch is
not activated during the KOER self test.
P1000 RESET
OBD Systems Readiness
Test Not Complete
This error occurs when all other DTC’s have been
erased from the system. This error will subside
when all OBD monitors have been completed.
P1102 X
Mass Air Flow Sensor In Range
But Lower Than Expected
This error occurs when the measured value of
mass air flow is lower than a threshold value
for a predetermined period of time.
0%< EGR Position < 50%
Engine speed >700 rpm < 2400 rpm
based on a table > 30sec
Wiring, MAF assembly, PCM
P1103 X
Mass Air Flow Sensor In Range
But Higher Than Expected
This error occurs when the measured value of
mass air flow is higher than a threshold value
for a predetermined period of time.
0%< EGR Position < 50%
Engine speed >700 rpm < 2400 rpm
based on a table > 30sec
Wiring, MAF assembly, PCM
P115A X
Low Fuel Level - Forced
Limited Power
This error occurs when the PCM recieves a signal
indicating that the vehicle is critically low on fuel.
P117B X
Exhaust Gas Temperature
Sensor Correlation
This error occurs when the three exhaust temperature
sensor readings are not within a specified temperature
range when compared to one another.
P117F X X
Fuel Pressure Regulator
Excessive Variation
This error occurs when any of the fuel pressure
corrections either become less than a minimum
threshold or more than a maximum threshold.
Low pressure fuel system,
injector leakage
P1184 X
Engine Oil Temperature Sensor
Out Of Self Test Range
This error occurs when the KOER self test is attempted but the
engine has not reached an operating temperature of 60º C.
EOT < 60 >205deg C NA
P120F X
Fuel Pressure Regulator
Excessive Variation
This error occurs when the difference between actual rail
pressure and the PCM’s calculated setpoint is large, and the
actual fuel pressure crosses the setpoint too frequently.
Wiring to FUP sensor,
FUP sensor, low pressure
fuel system
P127A X X X
Aborted KOER - Fuel
Pressure Failure
This error occurs when fuel pressure does not
rise sufficiently during the KOER self test.
Cannot achieve or return to 53
FUP_SP. Cannot achieve 139MPa
NA
P132A X X X
Turbocharger Boost
Control A Electrical
This error occurs if the turbocharger cannot perform
a sweep/learn of the min/max position.
P132B X X X
Turbocharger/Supercharger
Boost Control A Performance
This error occurs if a fault is detected
within the turbocharger actuator.
Internal to the turbocharger
control module
Wiring, SRA module,PCM
P132C X X X
Turbocharger/Supercharger
Boost Control A Voltage
This error occurs when the voltage to the
turbocharger actuator is below the threshold
for a predetermined period of time.
