6E-120 ENGINE CONTROL SYSTEM (4JK1/4JJ1)
DTC P0182 or P0183 (Flash Code 211)
Circuit Description
The fuel temperature (FT) sensor is installed to the fuel
supply pump. The FT sensor is a variable resistor and it
measures the temperature of the fuel entering the fuel
supply pump. The sensor has a signal circuit and a low
reference circuit. The ECM supplies 5 volts to the
signal circuit and a ground for the low reference circuit.
When the FT sensor is cold, the sensor resistance is
high. When the fuel temperature increases, the sensor
resistance decreases. With high sensor resistance, the
ECM detects a high voltage on the signal circuit. With
lower sensor resistance, the ECM detects a lower
voltage on the signal circuit. If the ECM detects an
excessively low or high signal voltage, DTC P0182 or
P0183 will set.
Condition for Running the DTC • The battery voltage is more than 9 volts.
• The ignition switch is ON.
• The engine run time is longer than 3 minutes. (DTC P0183)
Condition for Setting the DTC • The ECM detects that the FT sensor signal voltage is less than 0.1 volts for 3 seconds. (DTC P0182)
• The ECM detects that the FT sensor signal voltage is more than 4.75 volts for 3 seconds. (DTC
P0183) Action Taken When the DTC Sets
• The ECM illuminates the MIL when the diagnostic runs and fails. Refer to DTC Type Definitions for
Action Taken When the DTC Sets - Type A.
• The ECM uses a FT substitution of default value.
• The ECM limits fuel injection quantity.
• The ECM inhibits pilot injection.
• The ECM inhibits cruise control.
Condition for Clearing the DTC • Refer to DTC Type Definitions for Condition for Clearing the MIL/ DTC - Type A.
Diagnostic Aids • Before starting a cold engine, FT sensor and engine coolant temperature (ECT) sensor
temperature should be relatively close to each
other.
• If an intermittent condition is suspected, refer to Intermittent Conditions in this section.
• Use the Temperature vs. Resistance table to test the FT sensor at various temperature levels to
evaluate the possibility of a skewed sensor. A
skewed sensor could result in poor driveability
concerns.

6E-124 ENGINE CONTROL SYSTEM (4JK1/4JJ1)
DTC P0192 or P0193 (Flash Code 245)
Circuit Description
The fuel rail pressure (FRP) sensor is installed to the
fuel rail and it detects the fuel pressure in the fuel rail,
converts the pressure into a voltage signal, and sends
the signal to the ECM. The sensor has the following
circuits.
• 5 volts reference circuit
• Low reference circuit
• FRP sensor signal circuit
The ECM monitors the FRP sensor signal voltage.
Higher fuel rail pressure provides higher signal voltage
while lower pressure provides lower signal voltage. The
ECM calculates actual fuel rail pressure (fuel pressure)
from the voltage signal and uses the result in fuel
injection control and other control tasks. If the ECM
detects an excessively low or high signal voltage, DTC
P0192 or P0193 will set.
Condition for Running the DTC • DTCs P0652 and P0653 are not set.
• The battery voltage is more than 9 volts.
• The ignition switch is ON.
Condition for Setting the DTC • The ECM detects that the FRP sensor signal voltage is less than 0.4 volts. (DTC P0192) • The ECM detects that the FRP sensor signal
voltage is more than 4.75 volts. (DTC P0193)
Action Taken When the DTC Sets • The ECM illuminates the MIL when the diagnostic runs and fails. Refer to DTC Type Definitions for
Action Taken When the DTC Sets - Type A.
• The ECM uses a FRP substitution of default value.
• The ECM limits fuel injection quantity.
• The ECM inhibits pilot injection.
• The ECM inhibits cruise control.
Condition for Clearing the DTC • Refer to DTC Type Definitions for Condition for Clearing the MIL/ DTC - Type A.
Diagnostic Aids • If an intermittent condition is suspected, refer to Intermittent Conditions in this section.
• Electromagnetic interference may affect intermittent condition.

ENGINE CONTROL SYSTEM (4JK1/4JJ1) 6E-135
DTC P0217 (Flash Code 542)
Circuit Description
The engine coolant temperature (ECT) sensor is
installed to the thermostat housing. The ECT sensor is
a variable resistor and it measures the temperature of
the engine coolant. If the ECM detects an excessive
high coolant temperature, this DTC will set.
Condition for Running the DTC • DTCs P0116, P0117 and P0118 are not set.
• The battery voltage is more than 9 volts.
• The ignition switch is ON.
• The engine is running.
Condition for Setting the DTC • The ECM detects that the engine coolant temperature is more than 110 °C (230 °F) for 5
seconds.
Action Taken When the DTC Sets • The ECM will not illuminate the MIL or SVS lamp. Refer to DTC Type Definitions for Action Taken
When the DTC Sets - Type D. Condition for Clearing the DTC
• Refer to DTC Type Definitions for Condition for Clearing the DTC - Type D.
Diagnostic Aids • After starting the engine, the ECT should rise steadily to about 80 to 85 °C (176 to 185 °F) then
stabilize when the thermostat opens.
• Use the Temperature vs. Resistance table to test the ECT sensor at various temperature levels to
evaluate the possibility of a skewed sensor. A
skewed sensor could result in poor driveability
concerns.
• The Total Engine Coolant Overtemperature Events parameter on scan tool indicates number of
overheat events.
Notice: • This DTC is caused by an engine overheat condition (e.g. low engine coolant level). Since this
DTC does not illuminate any lamps, clear the DTC
and ensure there are no signs of engine damage.
Excessive engine overheat may damage internal
engine components.

ENGINE CONTROL SYSTEM (4JK1/4JJ1) 6E-137
DTC P0219 (Flash Code 543)
Circuit Description
The crankshaft position (CKP) sensor is located on the
left-hand of the cylinder block rear and it is behind the
starter motor. The ECM calculates the engine speed
and exact position of the crankshaft based on the
signal pulse from the CKP sensor. If the ECM detects
an engine overrun condition, this DTC will set.
Condition for Setting the DTC • The ECM detects that the engine speed is more than 4900 RPM (4JK1 standard output) or 4700
RPM (4JK1 high output and 4JJ1).
Action Taken When the DTC Sets • The ECM illuminates the SVS lamp when the diagnostic runs and fails. Refer to DTC Type
Definitions for Action Taken When the DTC Sets -
Type C. (Euro 4 Specification)
• The ECM illuminates the MIL when the diagnostic runs and fails. Refer to DTC Type Definitions for
Action Taken When the DTC Sets - Type A.
(Except Euro 4 Specification)
• The ECM limits fuel injection quantity.
• The ECM inhibits pilot injection.
• The ECM inhibits cruise control. • The ECM stops engine running when the vehicle
speed is lower than 5 km/h (3 MPH) for 5 seconds.
The engine will run after the key is cycled when the
ignition has been tuned OFF for longer than 10
seconds.
Condition for Clearing the DTC • Refer to DTC Type Definitions for Condition for Clearing the SVS Lamp/ DTC - Type C. (Euro 4
Specification)
• Refer to DTC Type Definitions for Condition for Clearing the MIL/ DTC - Type A. (Except Euro 4
Specification)
Diagnostic Aids • Make sure the CKP sensor is tight and the teeth are not damaged.
• Electromagnetic interference in the CKP sensor circuits may set this DTC.
• The Total Engine Overspeed Events parameter on scan tool indicates number of overrun events.
Notice: • This DTC is caused by an engine overspeed condition, which was most likely caused by driver
error (i.e. downshifting a manual transmission on a
steep grade). Excessive engine overspeed may
damage internal engine components.
