Fault symptom Possible cause
Poor speedup etc Man made fault1 2 3Throttle position sensorFault symptom Possible cause
Difficult to start Man made fault Repair precautions: pay attention to mounting position.
(2) Simple measuring method:
(Remove joint) turn digital multimeter to ohm position, connect
two meter pens with sensor 1 #, 2 # pin respectively, its resistance
value at room temperature is 2k ohm±20 %. Connect two meter pens
with 1 #, 3# pin respectively, rotate throttle, its resistance value shows
linear change with opening of throttle, while situation is reverse for
2 #, 3# pin.
Note: when observe change of resistance value, pay attention to observe whether has large leap.
3. Coolant temperature sensor
(1) This sensor is a negative temperature coefficient (NTC) thermistor, its resistance value decreases with
increase of temperature, but not a linear relationship. This thermistor is installed in a copper heat conducting sleeve.Engine EFI System-Engine EFI System5-121should drop.
Pressure sensor part: (connect joint), turn digital multimeter to DC voltage position, black meter pen is earthed,
red meter pen is connected with 3#, 4# pin respectively. In condition of idle speed, 3# pin should have reference
voltage of 5 V, 4 # pin voltage should be about 1. 3 V (specific value is related with vehicle type); in no-load
condition, open the throttle slowly, change of voltage of 4 # pin is not large; open the throttle quickly, voltage of
4 # pin may reach about 4V in no time (specific value is related with vehicle type), then it drops down to about
1. 5 V.
2. Throttle position sensor
(1) This sensor is actually corner potentiometer with linear output characteristic. Potentiometer tumbler is
mounted coaxially with throttle, when throttle rotates, it drives potentiometer tumbler to slide to certain position,
potentiometer outputs voltage signal proportional to throttle position. Mounting torque: 20 N.m(Max)
(2) Simple measuring method:
(Remove joint) turn digital multimeter to ohm position, connect two meter pens with sensor pins respectively,rated resistance at 20°C is 2.5 k ohm± 5%. Simulation method may also be used for measurement, specificprocedure is to put sensor work area into boiled water (pay attention to soak for sufficient time), observe changeof sensor resistance, now resistance should drop down to 300 ohm-400 ohm (specific value subjects to temperatureof boiled water).

4. Knocking sensor
(1) Knocking sensor is a vibration acceleration sensor. Mounted on engine cylinder body. Sensing element of
the sensor is a piezocrystal. Vibration of engine cylinder body is transferred to piezocrystal via mass block in the
sensor. Since pressure generated by vibration of mass block is applied to piezocrystal, it generates voltage on two
polar planes and turns vibration signal into voltage signal for output.5-122Symptom
Poor accelerationPossible cause
Various liquids, such as engine oil, cooling fluid, brake fluid, water etc
contact the sensor for a long time, which cause corrosion to the sensor. Mounting torque: 20 ± 5 N.M
Repair precautions: sensor must be fitted closely to cylinder body with its metal surface, any type of washer
is not permitted for installation. For wiring of sensor signal cables, note that do not let resonance occur to signal
cables, otherwise they might be broken. Energizing of high voltage between sensor 1 # and 2 # pins must be
avoided, otherwise piezoelectric element might be damaged.
(2) Simple measuring method:
(Remove joint) turn digital multimeter to ohm position, connect two meter pens with sensor 1 #, 2 # pin
respectively, its resistance value at room temperature should exceed 1M ohm. Turn digital multimeter to millivolt
position, use a hand hammer to tap near knocking sensor, now voltage signal output should be available.
5. Oxygen sensor
(1) Its sensing element is a ceramic tube, outside is open to exhaust, inside is open to atmosphere. When
temperature of sensing ceramic tube reaches 350°C, it will have the characteristic of solid state electrolyte. Just
utilizing this characteristic, it converts concentration difference of oxygen into electric potential difference, thus
forms electrical signal output. If mixed gas is a bit concentrated, inside and outside oxyanion concentration
difference of ceramic tube is high, electric potential difference is a bit high.
A large number of oxyanions move from inside to outside, output voltage is high (approximate 900mV); if
mixed gas is a bit thin, inside and outside oxyanion concentration difference of ceramic tube is low, electric
potential difference is low, only a small quantity of oxyanions move from inside to outside, output voltage is low
(approximate 100mV).
Possible cause
1. humid water vapor ingresses inside of sensor, temperature
changes rapidly, probe is broken.
2. oxygen sensor "is poisoned". (Pb, S, Br, Si) Symptom
Poor idle speed, poor speedup, tail gas
overproof, too high oil consumption1 2 3 4Oxygen sensor Mounting torque: 40-60 N.m
Repair precautions: it is prohibited to use cleaning fluid, oily liquid or volatile solid on oxygen sensor during
repair.
(2) Simple measuring method:
(Remove joint) turn digital multimeter to ohm position, connect
two meter pens with sensor 1# (white), 2# (white) pin respectively, its
resistance value at room temperature is 1- 6 ohm.
(Connect joint) in idle speed condition, when oxygen sensor
reaches its working temperature of 350°C, turn digital multimeter to
DC voltage position, connect two meter pens with sensor 3# (grey),Engine EFI System-Engine EFI System

Symptom Possible cause
Fail to start Man made faultSpeed sensor1 2 3Fault symptom Common cause
Dischrge overproof, increased oil consumption Man made fault5-1234#(black) pin respectively, now voltage should fluctuate quickly between 0. 1-0. 9V.
6. Speed sensor
(1) Use with oscillator. Oscillator is a fluted disc, originally has 60 teeth, but two teeth are absent. Oscillator
is mounted on crankshaft, and rotates with the crankshaft. When tooth tip passes by sensor end closely, the
oscillator which is made of ferromagnetic material cuts magnetic line of permanent magnet in the sensor, and
generates induced voltage in coil, which is output as rotating speed signal. Mounting torque: 8 ± 2 N.m
Repair precautions: use pressing in instead of hammering method for installation during repair.
(2) Simple measuring method:
(Remove joint) turn digital multimeter to ohm position, connect
two meter pens with sensor 2#, 3# pins respectively, rated resistance
at 20°C is 770-950 ohm.
(Connect joint) turn digital multimeter to AC voltage position,
connect two meter pens with sensor 2 #, 3# pins respectively, start up
engine, now voltage output should be available.
Suggestion: use oscillograph for vehicle use to check.
7. Phase sensor
(1) This sensor consists of a hall sensor and a rotor made of steel plate. Fix hall sensor, mount rotor on camshaft.
Rotor is a 180( range cylindrical face steel blade. When the blade covers hall sensor, high Level signal is output;
otherwise low level signal is output. This differentiates two different upper dead points. Repair precautions: avoid removing end cover as far as possible during repair, so as to avoid ingress of foreign
matter, which might result in abnormal damage of magnetic gate.
(2) Simple measuring method:
(Connect joint) turn on ignition switch but not start up engine, turn digital multimeter to DC voltage position,
connect two meter pens with sensor red, black conductors respectively, ensure reference voltage of 5V is available.
Start up engine, voltage output between green and black conductors should be available.
Suggestion: use oscillograph for vehicle use to check.
8. Idle speed regulator
(1) Idle speed regulator consists of a step motor and a sealing plug on its shaft, sealing plug may generate radial
displacement driven by step motor shaft, position of sealing plug determines extent of opening of by-pass airway,
so as to adjust the size of by-pass air quantity. Position of sealing plug is controlled by ECU output.Fault symptom
Too high idle speed, flameout at idle speedPossible cause
Since interior contamination is severe, regulating element
is blocked and leads to malfunction.
Repair precautions: dust and sand grain will result in damage of idle speed regulator. Intake air should be
filtered by dry air cleaner before entering idle speed regulator, filtration efficiency should exceed 99 %. ToEngine EFI System-Engine EFI System
