66f. The idle control valve is faulty;
g. The water temperature sensor is damaged;
h. The vacuum pressure sensor is damaged;
i. The air filter is blocked;
j. The injector leaks;
k. The compression pressure in the cylinder is too low;
l. The intake temperature sensor is damaged.
(3) Diagnosis and Troubleshooting
a. Check high pressure spark, check whether the high pressure spark on the ignition coil high pressure
bus and extension are OK, if the bus spark is week, replace the ignition coil, if the bus spark is OK
while the extension spark is too week, replace the ignition coil also; In addition, excessive spark
plug clearance will influence the starting feature, the clearance of the spark plug shall be adjusted
to normal value (0.8±0.1mm);
b. If there is low fuel pressure, check whether the battery voltage is OK, otherwise it shall be
troubleshot or replaced; check fuel pump check valve for leakage, check fuel filter and fuel pipe for
block, if there are leakage or block, replace or troubleshoot them;
c. If there is leakage for fuel pressure regulator, intake manifold is likely to be mixed with gasoline and
it is hard to start, troubleshoot or replace them;
d. Idle control valve can not be opened to maximum position due to mechanical wear, aging or control
circuit failure, the idle control valve shall be replaced and the control circuit failure shall be troubleshot;
e. If the water temperature sensor data is not accurate, it may cause small injection, check the water
temperature sensor based on the standard data and calibrate the data;
f. There is big time lag for intake pressure temperature sensor that makes it somewhat insensitive at
low speed and result in inaccurate injection, adjustment or replacement shall be made;
g. If the air cleaner filter is too dirty, the air flow resistance is excessively big, resulting in hard start,
as a result of it, the filter shall be replaced.
In a word, there are many factors causing the starting failure of the engine, analysis shall be made based on
the severe conditions of the faults. Generally speaking, check the ignition system first, then check intake
system, fuel system, control system, at last check the cylinder pressure, check the DTC before checking the
trouble. The diagnosis and troubleshooting procedures for starting failure of the engine are shown in (Figure
148).

724. Big fuel consumption

5. Unstable idle, liable to be turned off
(1) Symptom:
Engine starts normally, but the idle is unstable regardless of cold or hot status, idle speed is too low and
the engine is liable to be turned off.
(2) Causes and Troubleshooting
a. Poor idle control valve operation, repair or replace it;
b. Low idle speed and faulty or improperly adjusted idle control valve, troubleshoot it;
c. Water temperature sensor fault, repair or replace it;
d. Poor intake system seal, need to be repaired;
e. High voltage spark is too weak, spark plug carbon deposit or electrode clearance is too small, need
to be repaired, cleared and adjusted;
f. Pressure sensor fault, repair or replace it;
g. The compression pressure in the cylinder is too low, need to be serviced;
h. Fuel line pressure is too low, needed to be serviced;
i. Air cleaner is clogged, clean or replace it;
j. Poor injector atomization, fuel leakage, block or big injection variation, need to be repaired;
(3) Diagnosis procedure (Figure 152)
6. Unstable idle at cold status, liable to be turned off
(1) Symptom
During the cold start, idle is unstable and engine is liable to be turned off, the normal idle is recovered
after warming of the engine.
(2) Causes and Troubleshooting
a. Water temperature sensor fault, repair or replace it;
b. idle control valve fault, repair or replace it.

83ECU microcomputer consists of microprocessor, memory, clock generator, timer, I/O interface and input
level A/D converter that are integrated in a large scale integrated circuit chip, that is SCM (Single Chip
Microcomputer).
1. Input level
The input signals from the sensor are pre-processed by the input level. The input signals are sent to protected
circuit first, sometimes through the signal converter and amplifier, and then sent to microcomputer.
The sensor signal is separated into switch type and analog type. Ignition on/off signal, camshaft position
signal, vehicle speed signal and A/C signal are switch type; Signals such as battery voltage, engine temperature,
intake temperature, airflow, intake manifold absolute pressure, throttle opening, excessive air coefficient,
knock, A/C refrigerant pressure are analog type. Analogy signal can only be processed by the digital micro-
computer after being converted into digital signal by A/D converter. Hence, data collection shall be made
first for analog signal, and the sampling shall be maintained also.
Speed and crankshaft position reference signal from the sensor is processed in a dedicated circuit to restrain
the interference pulse.
2. Microcomputer
The microcomputer of the engine electronic control unit is integrated in a single chip microcomputer, consist-
ing of the following:
(1) Microprocessor, microprocessor is also called as central processing unit (CPU), consisting of the following
three parts:
Arithmetic logic unit.
Register group.
Controller.
(2) System assembly, The data transferred among the internal sections of the single chip microcomputer
(SCM) is performed on the internal bus, while that between the SCM and other components is performed
on the external bus. The external bus is also called system bus. It is separated into data bus, address bus
and control bus.
(3) Memory, the memory is designed to store the binary data. The primary components of the memory are:
Memory.
Data register.
Address register, address decoder.
a. Memory controller
(4) A/D converter
(5) I/O interface.
(6) Clock generator.
(7) Timer
(8) CAPCOM unit.
(9) Watchdog timer.
(10) Interrupt system.
