Fault symptom
Flameout, poor idle speedChapter 9 Engine EFI SystemI. Outline This system includes sensor that detects engine functioning. Engine ECU utilizes sensors installed at differ-
ent parts of engine to measure various working parameters of engine, accurately control oil injection quantity
according to control procedure set in engine electronic control unit, so engine could work in optimum mode
under various operating conditions, i. e. optimal power output, the most economical oil consumption, optimal
exhaust emissions. Engine ECU is capable of start up control, idle speed closed-loop control, air fuel ratio
closed-loop control, canister control, transient operation control, angle of ignition control, knocking control, air
conditioning control, coasting fuel cutoff and overspeed fuel cutoff control, ternary catalyst heating and protec-
tion control, system self-diagnosis etc.II. Inspection of control element1. Manifold intake pressure temperature sensor
(1) The part to measure intake pressure is piezo type sensor, could provide controller with "load signal "
according to the difference between atmospheric pressure and manifold pressure; controller will supply 5V
voltage, and feed back 0-5V voltage to controller according to different intake pressures. The part to measure
intake temperature is NTC type (negative temperature coefficient) sensor, resistance changes with intake
temperature, this sensor conveys a voltage representing intake temperature change to the controller.
(2) Simple measuring method:
Temperature sensor part: (remove joint) turn digital multimeter
to Ohm position, two meter pens connect sensor 1 #, 2 # pinrespectively, rated resistance is 2. 5k ohm±5% at 20°C, correspond-ing resistance value may be measured from the above characteristic
curve. Simulation method may also be used for measurement, spe-
cific procedure is to use electric drier to blast sensor (pay attention not
to be too close), observe change of sensor resistance, here resistanceEngine EFI System-Engine EFI System5-120Possible cause
There is abnormal high voltage or reverse heavy current during useVacuum
unit is damaged during repair
Repair precautions: it is prohibit to use high pressure gas to impact vacuum unit during repair; when replace
sensor case of trouble, check whether generator output voltage and current is normal or not.1 2 3 4Manifold intake pressure temperature

Engine ECU5-126as to avoid damaging electronic control unit.
(1) Simple measuring method:
(Remove joint) turn digital multimeter to ohm position, connect two meter pens with primary winding pinsrespectively, rated resistance at 2 0°C is 0. 4-0. 6 ohm for 2X2 type; on secondary winding, 11-15k ohm for 2x2 type.13. Electronic control unit ECU
Possible cause
Electric overload of externally connected
device leads to burnout of components inside
ECU and results in malfunction Symptom
Unsteady idle speed, poor speedup, failure to start, too high
idle, tail gas overproof, difficult to start, malfunction of air
conditioner, malfunction of fuel injector control, flameout
Repair precautions:
1. Don't remove ECU at discretion during repair;
2. ECU may be removed more than 1 minute after removing storage battery head;
3. Store removed ECU properly;
4. It is prohibited to attach any circuit onto connecting wire of ECU.
Simple measuring method:
1. (Connect joint) use engine data K-line to read engine trouble record;
2. (Remove joint) check whether ECU connecting wire is in good condition or not, mainly check whether ECU
power supply grounded circuit is normal or not;
3. Check whether external sensor works normally, whether output signal is credible, whether circuit is in good
condition;
4. Check whether actuator works normally, whether its circuit is in good condition;
5. Finally replace ECU to conduct test.
Judgment principle: "two interchange principle" ---interchange ECU, interchange fault symptom.III. Diagnostic system Description:
When engine ECU detects a trouble, engine trouble warning lamp on instrument will illuminate. In addition,
relevant diagnostic code will be recorded in ECU memory. Connect handheld tester with diagnostic interface on
automobile, read various data from automobile ECU. Connect handheld tester with diagnostic interface. Technical
personnel may also read fault code via blinking of instrument fault warning lamp.Engine EFI System-

procedure: use engine data K-line (namely 9 # terminal of diagnostic interface) earth twice, earthing time is more
than 2. 5 s at each time.
