there is no injection confirmation signal (IJF) from EDU to
ECM, despite the ECM sending injection command signal
(IJT) to the EDU.

MONITOR DESCRIPTION
P0200 (Open or short in EDU or injector circuit):
The ECM always monitors both the injection command signal (IJT) and injection confirmation signal (IJF).
This DTC will be set if the ECM judged that the number of IJT signals and IJF signals are inconsistent.
The EDU monitors a drive current supplied to the injector and interprets the IJF signal as low if the current
exceeds the specified level, and then it indicates that there is the current in the injector.
P0200 refers to malfunction of injector drive circuit or injector circuit.
If this DTC is present, the ECM enters fail±safe mode and limits the engine power. The fail±safe mode will
continue until the ignition switch is turned OFF.

CIRCUIT DESCRIPTION
Refer to DTCs P0087 on page 05±557.
INSPECTION PROCEDURE
HINT:

If DTCs ºP0087, P0190, P0192,and P0193º are output simultaneously, manifold absolute pressure
sensor circuit may be open or short. Perform the troubleshooting of DTC ºP0087, P0190, P019\
2,and
P0193º first.

Read freeze frame data using the hand±held tester. Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, it is useful for deter\
mining whether the vehicle
was running or stopped, the engine was warmed up or not, etc. at the time o\
f the malfunction.

CIRCUIT
DTC P0182 FUEL TEMPERATURE SENSOR ºAº
CIRCUIT LOW INPUT
DTC P0183 FUEL TEMPERATURE SENSOR ºAº
CIRCUIT HIGH INPUT
CIRCUIT DESCRIPTION
The fuel temperature sensor senses the fuel temperature. A
thermistor built into the sensor changes the resistance value
according to the fuel temperature. The lower the fuel tempera-
ture is, the greater the thermistor resistance becames, and the
higher the fuel temperature is, the lower the thermistor resis-
tance becomes (See Fig. 1).
The fuel temperature sensor is connected to the ECM (See be-
low). The 5 V power source voltage in the ECM is applied to the
fuel temperature sensor from terminal THF via a resistor R. The
resistor R and the fuel temperature sensor are connected in se-
ries. When the resistance value of the fuel temperature sensor
changes in accordance with changes in the fuel temperature,
the potential at terminal THF also changes. Based on this sig-
nal, the ECM performs the pressure control compensation of
the supply pump and error detection compensation of the highly
pressurized fuel system.
