Brief Description
This error is set when the change in IAT2 is 5ºC less
than specified over a predetermined period of time.
This error is set when the IAT2 sensor temperature
output provides a value higher than a maximum probable
temperature (lower voltage reading) for a predetermined
period of time, which indicates a short to ground.
This error is set when the IAT2 sensor temperature output
provides a value lower than a minimum probable temperature
(higher voltage reading) for a predetermined period of time,
which indicates an open circuit or a short to power.
This error occurs when the PCM detects a
MAF sensor that is sending no signal.
This error occurs when the value of the mean
period time per ms of the mass air flow sensor
is less than a calibrateable value.
This error occurs when the value of the mean
period time per ms of the mass air flow sensor
is greater than a calibrateable value.
This error occurs when the MAF senor change is
too great over a predetermined period of time.
This diagnostic compares MAP and BP pessures at idle
conditions, when they should be within a specified range.
This error is set if the MAP sensor reading is above or
below the thresholds for a predetermined period of time.
This diagnostic checks for a minimum intake manifold
pressure, indicating an open circuit or a short to ground.
This error occurs when the MAP signal voltage is lower
than a specified value for a predetermined period of time.
This diagnostic checks for a maximum possible intake
manifold pressure, indicating a short to power. This
error sets when the MAP signal voltage is higher than a
specified value for a predetermined amount of time.
This error occurs if the input signal from the intake air
temperature sensor falls below a minimum calibrateable
threshold for a predetermined period of time.
This error occurs if the input signal from the intake air
temperature sensor rises above a maximum calibrateable
threshold for a predetermined period of time.
This error sets if the gradient of measured intake air
temperature sensor outputs is outside of a threshold.
This error is set when the ECT sensor signal is lower than
the minimum threshold for a predetermined period of time.
This error sets when the ECT sensor signal is higher than a
maximum threshold for a predetermined period of time.
This error occurs when the ECT sensor signal indicates a
coolant temperature lower than the operating temperature
of the thermostat for an extended period of time.
This error sets when injections are detected
although they are not commanded.
This error occurs when fuel temperature
exceeds a predetermined temperature.
This error occurs when the difference of the minimum
and maximum fuel temperature exceeds a threshold.
This error occurs when the FTS temperature output
is higher (lower voltage signal) than a maximum
probable temperature, indicating a short to ground.
