MONITOR DESCRIPTION
When starting a cold engine, the ECM supplies the current to the glow plug for a certain period of time. As
the supplying current to the glow plug is terminated, the large current is suddenly cut off, therefore the battery
voltage then varies and also terminal M output (duty ratio) of the generator varies. If these variations are not
occurred when the glow plug is turned from ON to OFF, or vice±versa, the ECM realizes that the current has
not been supplied to the glow plug, and interprets this as open malfunction of the glow plug or glow plug
circuit.

DTCP0340CAMSHAFT POSITION SENSOR ºAº CIRCUIT (BANK 1 OR SINGLE SENSOR)
CIRCUIT DESCRIPTION
Camshaft position sensor (G signal) consists of a magnet, iron core and pickup\
coil.
The G signal plate has one tooth on its outer circumference and is installe\
d on the camshaft timing pulley.
When the camshafts rotate, the protrusion on the signal plate and the air ga\
p on the pickup coil change,
causing fluctuations in the magnetic field and generating an electromoti\
ve force in the pickup coil.
The NE signal plate has 34 teeth and is mounted on the crankshaft timing pu\
lley. The NE signal sensor gen-
erates 34 signals at every engine revolution. The ECM detects the standard crankshaft angl\
e based on the
G signal and the actual crankshaft angle and the engine speed by the NE s\
ignal.

2. DATA LIST
HINT:
According to the DATA LIST displayed on the Hand±held tester, you can read the value and status of the
switch, sensor, actuator and so on without parts removal. Reading the DATA LIST as a first step of trouble-
shooting is one of the methods to shorten the labor time.
(a) Connect the Hand±held tester to the DLC3.
(b) Turn the ignition switch ON.
(c) From the display on the tester, read the ºDATA LISTº.

DTC P0753 SHIFT SOLENOID ºAº ELECTRICAL (SHIFT
SOLENOID VALVE S1)
DTC P0758 SHIFT SOLENOID ºBº ELECTRICAL (SHIFT
SOLENOID VALVE S2)
CIRCUIT DESCRIPTION
Shifting from 1st to O/D is performed in combination with ON and OFF operation of the shift solenoid valves
S1 and S2 controlled by ECM. If an open or short circuit occurs in either of the solenoid valves, the ECM
controls the remaining normal solenoid valve to allow the vehicle to be operated smoothly (Fail safe func-
tion).
Fail safe function:
If either of the solenoid valve circuits develops an open or short, the ECM turns the other solenoid valve ON
and OFF to shift to the gear positions shown in the table below. The ECM also turns the shift solenoid valve
ST OFF at the same time. If both solenoids malfunction, hydraulic control cannot be performed electronically
and must be done manually.
Manual shifting as shown in the above table must be done (In the case of a short circuit, the ECM stops send-
ing current to the short circuited solenoid).

3.DTC CHECK (SENSOR CHECK)
(a)After the indicator check is completed, the system enters the DTC check mode automatically.
(b)Read the codes displayed on the panel. Refer to the list of codes on page 05±1094 when reading the codes.
(Trouble codes are outputed at the temperature display.)
(c) If the slower display is desired, press the DEF switch and
change it to the stop operation. Each time the DEF switch
is pressed, the display changes by 1 step.
4. CLEARING DTC
(a) To clear diagnostic trouble code, there are 2 ways. (1) During sensor check, press the ºDEFº switch andºDUALº switch at the same time.
(2) Pull the ECU±B2 fuse in fuse block for 20 seconds or longer to clear the DTC memory.
5. CHECK DLC3
(a) The vehicle engine and ECT ECU uses the ISO 9141±2 (Euro±OBD)/ISO 14230 (M±OBD) communication proto-
col. The terminal arrangement of the DLC3 complies with
ISO 15031±3 and matches the ISO 9141±2/ISO 14230
format.
